Ben and Van 10!

by Vgn Golley

Vanessa Cunningham was expecting to go on a normal summer vacation with her childhood best friend and his family, but that all changed when an alien space pod crashes down on their campsite while carrying a pair of strange devices called 'The Biomnitrix'. Now Ben and Vanessa go on epic adventures of fighting supervillains, monsters, sorcerers, aliens, and all sorts of other things.

15. Need for Speed!

Hey, guys. Welcome to the new chapter of Ben and Van 10. I hope that you guys like the chapter...anyway, I don't own anything except for my OCs, as the OC Rook Shadow belongs entirely to 9655. Also, I want to mention that Crow Reaper and Fastodactyl are RZGmon200's creations as he let me borrow his Ben 10 OC Fusion and Predator Aliens after asking for permission.

NOW LET'S GET ON WITH THE STORY!

{Season 1, Episode 15: Need for Speed!}

"Ah, just as beautiful as I remember it, kids." A smiling Max says as it is a normal day for the Bio-Team, and we see them driving through the streets in the Rust Bucket as they arrive at Yellowstone National Park, and Grandpa Max was driving the vehicle around while the kids sat behind him as Gwen and Rook Shadow sat in one side of the booth as they were researching stuff on Gwen's Computer and Ben and Vanessa sat in front of them as they were doing their own research on Van's Tablet and Katmeleon sat in their laps as the Aliens and Mutants weren't wearing their ID Masks. "Now, I know you guys aren't usually excited about the places we visit, but-,"

"No way. We've been researching Yellowstone all morning." Rook Shadow says as Ben nods excitedly.

"Yeah, some people on the Internet think there's treasure buried here."

"And if there's one thing that makes a trip exciting, it's a good old treasure hunt," Van says with a giggle as she and Ben share a high five as Max laughs awkwardly.

"Well, uh, kids, that's probably just a metaphor. There's no literal treasure."

"That's what they want you to think," Katmeleon added as Gwen rolled her eyes playfully.

"Sure, whatever. Look at all these geysers." Gwen says with a beaming smile as she shows the others her laptop. "They're fueled by super-heated pressurized water chambers, and under all that, there's a super volcano. One well-placed earthquake and this place is history." Gwen says as the others look impressed by this piece of news.

{Intro}

A green glowing steel pod was flying across the Milky Way Galaxy as it reached Earth and crashed down as a huge green flash occurred. Once the flash dies down, we see the glowing symbols of the Biomnitrix as the camera zooms out, and we see Ben and Vanessa looking at their new devices in wonder as the kids then glance at each other before smirking as they activate their gauntlets and two cores popped out as Ben and Vanessa raised their hands in the sky dramatically before slamming them down on their individual Biomnitrix's.

The area around them turned green as Ben slowly morphed into Four Arms and pumped his fists into the air in victory while Vanessa transformed into Coldphase as she opened up her wings and flew in the air as she generated an ice mace in her hand, and white number 1 appeared beside them.

Ben and Van 10!

Ben then quick-changed into Heatblast as he manifested a fiery cyclone around him, but the transformed boy lost control of it as the tornado began to grow. Vanessa reacted quickly and transformed into Blitz as she ran around the fire tornado and snuffed out the infernal hurricane, but accidentally canceled out Heatblast's fire in the process as well. The magma-being gave his friend a deadpanned look as Vanessa gave him a sheepish grin and a white number 2 appeared beside them.

Ben and Van 10!

Huffing in annoyance, Heatblast glared at the Citrakayah until an idea popped into his head as Ben grinned mischievously. Quick-changing into XLR8, the Kineceleran puts on his visor as he begins running circles around Blitz. Vanessa yelped as the fast winds from XLR8 forced her to fall to the ground, and XLR8 stopped running as he laughed at her immaturely. Vanessa growls at him in anger as she quick-changed into Split and duplicates herself up to 30. XLR8 yelped in surprise as Split and her clones dogpiled on the surprised Kineceleran, and a white number of a 3 appeared beside them.

Ben and Van 10!

Split and her clones smirked at each other in victory until they felt something rumbling below them as a flash of green light appeared, and they were all thrown into the air by large crystal spikes. Diamondhead rose up from the ground as he raised his hands, and encased each clone in small crystal cages as they struggled to free themselves. Diamondhead crossed his arms smugly before blinking in shock as all the Splits merged with each other and transformed into Vortex. The cloud-like alien turned herself into the air as she easily escaped from Diamondhead's crystal trap, and a white number 4 appeared beside them.

Ben and Van 10!

Not giving up the fight just yet, Ben quick-changed into Cannonbolt as he curled up into a ball and rolled over to Vortex, who stood perfectly still as she transformed into Fairytail and used her magic to conjure a slide in front of Cannonbolt. Ben's eyes widened from inside his shell as he went up the slide, and flew in the air as he crashed against the green background, and groaned as a white number of a 5 appeared beside them.

Ben and Van 10!

Fairytail giggled amusedly under her breath as Cannonbolt glared at her in annoyance and transformed into Upgrade as he turned into a puddle and slithered his way toward an unsuspecting Fairytail. Without giving her time to react, the Galvanic Mechamorph used his elasticity to wrap around her body as Fairytail struggled to escape from his grasp. Vanessa grunted before quick-changing into Tricetaurus as she burst out of Upgrade's hold and roared as a white number of a 6 appeared beside them.

Ben and Van 10!

Upgrade rubbed his head with a moan as a large shadow fell on top of him and gulped as he saw Tricetaurus glaring down at him as she raised her foot to smash him and dropped it down. Luckily, Ben transformed into Grey Matter just in time as he dodged her and jumped up to her leg as he begins crawling all across her body. Tricetaurus tried to smack him, but Ben easily avoided her attacks as he crawled to the top of her head and Vanessa glared at him as she tried to hit him, but he managed to jump out of the way in time as Vanessa accidentally smacked herself on the face, and fell down. Grey Matter laughed at her as Vanessa blushed embarrassedly and glared at him as she transformed into Snatcher and morphed into a more buffed version of Grey Matter. Before Ben could react, Snatcher leaps toward him, and the shapeshifter tackles him to the floor, and a white number of 7 appears beside them.

Ben and Van 10!

Grey Matter struggled to escape from the chokehold that Snatcher was giving him as he thought quickly and swiftly transformed into Overflow as Snatcher lost her grip on him, and she fell down to the floor. Overflow smirked down at the terrified Snatcher as he raised his hand and washed her away with a burst of water as Snatcher's physical form dissolved into a puddle of goo. Snatcher glared at the smirking Cascan before transforming into White Fang as she hissed at him and jumped onto his head. Ben struggled to push her off as White Fang used her sharp claws to scratch him but couldn't slice through his hard exoskeleton as a white number of an 8 appeared beside them.

Ben and Van 10!

Overflow grunted before transforming into Wildvine as he used his large plant tendrils to grab Vanessa's slim waist, and he threw her off. White Fang landed in a low crouch as she growled at him and transformed into Kralastico as she extended her hands and fists blew up to ridiculous proportions. Wildvine and Kralastico glared daggers at each other as they took off into a sprint and raised their fists just as a white number of a 9 appeared above them.

Ben and Van 10!

Wildvine and Kralastico struggled to free themselves as they accidentally tied themselves up with their stretched-out limbs during the fight. Kralastico whimpers and Wildvine stared at her worriedly before grinning as an idea popped into his head. Whispering his plan into Vanessa's ear, Kralastico nodded with a smile as Ben transformed into Stinkfly, and Vanessa morphed into Freakazette as they escaped from their bonds. Stinkfly flew in the air happily as Freakazette popped up behind him and pulled out a sign with a white number 10 on it from her hammerspace.

Ben and Van 10!

Happy to not be fighting anymore, Stinkfly and Freakazette smiled at each other warmly as the young cartoony devil-like alien reached out, and she literally flipped the scene around as we see Ben and Vanessa standing in a large white room while back in their human forms as Max, Gwen, Katmeleon, and Rook Shadow stood beside them.

Ben shared a low five with his grandfather and male best friend while Vanessa shared a hug with the red-head girl and mutant pet as Ben and Vanessa then stared at each other for a few seconds before blushing as they shyly held hands, and the others laughed at this amusedly before everyone goes serious as Ben, Van, and Rook Shadow smirked cockily while holding out their Biomnitrixes, Omnitrix, and Nemetrix as a determined Gwen transformed into her Titan Girl Form and flew up into the air as her fists lightning up with yellow godly electricity as a smirking Max Tennyson puts on his Plumbers Uniform and pulled out an alien blaster as Katmeleon laid on his shoulder and roared cutely as all of the Alien Shapeshifter's Fusion Aliens appeared beside them.

{Intro Over}

"You know, I'm feeling good about camping today." A smiling Ben says as we fast forward in time and we see the Rust Bucket parked in a meadow placed in Yellowstone National Park as everyone got out of the vehicle and Max and Gwen were setting up the tents as Rook Shadow helped set up the grill and their food for later at night as Ben and Van returned from the woods after getting tons of firewood as Katmeleon slept on the ground, enjoying some sunrays.

"Sure you are." A bemused Van says before she, Ben, and Rook Shadow spotted what seems to be a pair of familiar evil sisters walking past them as they grew suspicious.

Standing before them is a 5'8-feet-tall, 45-year-old Woman with her right eye being black as her left eye was pure white, long brown hair that reaches down to her back as it was tied up into a bun, thin black eyebrows, a small nose, a sharp shin, E-Cup Breasts, Caucasian Skin, a tall muscularly slender build, a perky ass, and her outfit consists of a black eyepatch over her left blind eye, a plain short-sleeved white t-shirt, a brown belt with a golden belt buckle, long blue jeans and a pair of black sneakers. Her name is Marge Malachi, a member of the Malachi Sisters, Mel's Older Sister, and an illegal racer as she and her sister ride around in a Monster Truck.

Standing before them is a 5'6-feet-tall, 43-year-old Woman with a pair of black eyes, long black hair that reaches down to her neck and was parted to the right side of her face, thin black eyebrows, a small nose, a sharp shin, C-Cup Breasts, Caucasian Skin, a tall muscularly slender build, a bubble butt, and her outfit consists of a sleeveless denim jacket with a ripped white shirt that had torn sleeves, a pair of black wristbands, a black belt with a silver belt buckle, long green jeans, and a pair of black boots. Her name is Mel Malachi, a member of the Malachi Sisters, Marge's Younger Sister, and an illegal racer as she and her sister ride around in a Monster Truck.

"What are we doing here again?" Marge says as Mel turns to her curiously.

"I don't know, something about treasure!" Mel yelled as Ben and the others shared a surprised look.

"Don't be so loud, dummy. Use your inside voice."

"But we're outside!" Mel screamed as she and Marge walked off as the trio shared a look and nodded as they turned back to the others.

"Hey, Grandpa, Van, Shadow, and I are gonna go check out nature or whatever."

"Okay, kids, don't go too far." A distracted Max says as the kids then off as, once they are far away from the others, Ben and Van press a button on their Biomnitrixes to have their devices suit them up into their Omni-Naught Armor as the trio follows after the Malachi Sisters as they arrived at the Ranger Station, which had a bunch of vehicles parked in front of it as Bio-Man, Bio-Girl, and Rook Shadow hid behind a car as they spotted the Malachi Sisters walking up to the door and knocked on it as the door opened up and a familiar villain popped out as he allowed them to get inside.

Standing before them is a 6'3-feet-tall, 42-year-old man with light blue eyes, short shaved slick back white hair, a pointy nose, a sharp chin, tan Caucasian Skin, a slim muscular build, and his outfit consists of a full-body skintight black racing suit with a hood that acts as a mask as it covers his whole face except for his mouth as the hood has a pair of red lenses, red shoulder pads, an armored red chest with a white lightning bolt symbol planted in the middle, white gloves, a white belt with a red center, red kneepads, and white boots. His name is Lucien LaGrange, an Illegal Racer and occasional Bank Robber.

"Oh, no! LaGrange!" Bio-Man, Bio-Girl, and Rook Shadow exclaimed in unison with the camera zooming in on their eyes briefly before zooming out as Ben and Van told Shadow about LaGrange being one of the first villains that they had fought in their first week of summer.

"Huh? Who is there?" LaGrange asked suspiciously while walking over to the source of the strange noise as the trio flinched worriedly and reacted quickly as Bio-Man, Bio-Girl, and Rook Shadow swiftly activated their Biomnitrixes and Omnitrix before slamming their hands down on their alien devices as triple flashes of green and purple lights rang out, startling the Illegal Race Car Driver as he rushed over to peek behind the car, but didn't see anything as LaGrange hummed and shrugged while turning around to leave, not noticing Grey Matter peeking out from behind a rock, which is really Snatcher shapeshifted herself into a rock as an invisible Ghostfreak floated above them, and the trio shared a look as they nodded and Van morphed herself into a bird as she allowed Ben to climb up her back and flew off with Ghostfreak following after them as they made their way over to either land on the windowsill or hover in front of it as they spotted LaGrange, the Malachi Siters, and a couple of people standing inside of the Ranger Station as they spotted a couple of rangers tied up inside.

Standing before them is a 5-feet-tall, 37-year-old Man with black eyes, a bald head with black sideburns, thick black eyebrows, a big stumpy nose, a sharp chin with a shaved beard, Caucasian Dirty Skin, a short fat build, and his outfit consists of blue overalls with a long-sleeved white shirt underneath, a pair brown fingerless gloves, and a pair of brown boots. His name is Dirty Dobbs, an Illegal Racer who has horrible hygiene and has flies floating above him.

Standing before them is a 6'6-feet-tall, 60-year-old Man with brown eyes, a bald head, no eyebrows, a big pointy nose, a cleft chin, caucasian skin with tattoos placed all over his body as his right arm has a skull with bones and a scorpion and his left arm has a flower tattoo, a tall very muscular top-heavy build, and his outfit consists a silver necklace with a skull around his neck, a black tank top, a black belt with a white skull in the middle, long blue jeans, and a pair of white/black shoes. His name is Vincent 'Vin' Ethanol, an illegal racer.

"I am glad to see you all made it; the Malachi Sisters, Dirty Dobbs, and Vin Ethanol."

"LaGrange, it's been a while since we have seen you." Marge says as Mel nodded in agreement.

"Yeah, where have you been?"

"Oh, you know about the Bio-Team, right? Well, the last time I fought them, I was accidentally sent to another dimension from this machine that I tried to steal to improve the speed of my car and I got sent to a dimension where there was a planet filled with heroes and I raced this blonde-haired teenage girl who has some serious road rage and-You know what? It doesn't matter where I was and how I came back. Everyone, take a map." LaGrange says as he then handed everyone several maps of Yellowstone National Park. "It outlines the details of today's race course."

"Yo, but this goes through miles of protected environmental habitats." Vin pointed out with a serious frown on his face after taking a look at his map as he crossed his arms.

"Of course it does. We will race through the Grand Prismatic Springs, through the geysers, across the mud pots, and, finally, into an abandoned cavern...which happens to be the location of the legendary lost treasure of Yellowstone."

"Whoa, real life treasure. I knew that it exists." An excited Snatcher says as Grey Matter and Ghostfreak nod in agreement as they are then surprised when Gwen appears out of nowhere while having Katmeleon ride around on the top of her head as she eyes them curiously.

"Guys, what are you doing? Why are you sneaking near the ranger station?" Gwen asked just as Ghostfreak turned himself visible as she screamed in surprise, and Snatcher quickly allowed Grey Matter to get off her back as she swiftly morphed back into her normal form and placed her hand over Gwen's mouth to shut her up.

"Disengage the communication orifice, Gwendoline."

"Excuse me?" Gwen asked confusedly as Grey Matter sighed heavily and jumped down to land on the ground as he and the others reached up to slam their hands against their Biomnitrixes and Omnitrix Symbols to Quick Change back into their Normal Forms with triple flashes of green and purple lights.

"I mean, be quiet, Gwen," Bio-Man shushed as Gwen frowned but nodded as the kids turned around to glance through the window into the Ranger Station again.

"How do we know there's even any treasure there?" Vin asked as Marge turned to him with a mocking smirk on her face.

"You afraid your car can't handle the dirt?"

"Yeah, you some kind of chicken or something?" Mel asked as Vin glared at them seriously.

"Yo, listen. Real racing is in the streets."

"Please, save your energy for the race. Treasure there is. Genius you must possess. You will need it to beat LaGrange, my friends." LaGrange says with a sly smirk as Vin scores and rolls his eyes.

"I don't have friends. I have family."

"You were right, guys, there really is treasure in Yellowstone National Park, and they're gonna race for it." A concerned Gwen says as Ben grinned excitedly.

"And if we can get there first, I will be able to build Cybearg."

"And I will be able to have enough money to build a totally awesome superhero lair for the Bio-Team to build when we are older back in Bellwood." A giggling Van says as Rook Shadow smirks.

"And I want the treasure to buy a romantic gift for a certain someone and to give some treasure to my little sister Knight-Oh, shit! Duck!" Rook Shadow ordered after spotting LaGrange and the others emerging out of the Ranger Station as the Bio-Team quickly hid in the bushes and watched on as everyone got into their respective vehicles and drove off.

"Alright, it's time to transform, guys." Rook Shadow says to the others, who nod as he and the Biomnitrix Wielders swiftly activate their Biomnitrixes and Omnitrix before slamming their hands down on their alien devices as triple flashes of green and purple lights rang out, and once they die down, we see the trio transforming themselves into-

"XLR8-Aw, man, Diamondhead..." A groaning Diamondhead says as he facepalmed.

"Blitz-Oh, uh, I mean, Fairytail!" Fairytail screamed as she flew up into the air.

Once the flash of purple light died down, we see Rook Shadow transforming himself into a 20-foot-tall Male Slammoid as he resembles a giant worm-like alien with six purple eyes, a wide gray beak-like mouth with a row of sharp teeth, a creamy orange/brown hide with a white-brown underbelly, four purple insectoid legs on each side near the front, grey spikes running down his back, a tail ending in a pincer-like a set of spikes, and has the Nemetrix Symbol planted on his stomach. His name is-

"Slamworm!" The Now-Named Slamworm yelled through the communication system placed inside of the Nemetrix Symbol as it beeped red every time he talked, and a bemused Gwen glanced up at her friends.

"Okay, how about you guys go and free those rangers while I go and get Grandpa Max?" Gwen suggested as the trio nodded, and Diamondhead and Fairytail turned around to go into the Ranger Station to free the tied-up Rangers while Slamworm stayed behind due to being too big to fit into the building.

"It's Titan Time!" Gwen exclaimed while glancing down at her hands and flexing them, causing her pair of fingerless blue leather gloves to be covered by small flashes of golden light as they transformed into her Titan Gauntlets, and a grunting Gwen proceeded to slam her fists together as her body was soon covered with a bright golden light, and once the flash of golden light died down, we see Gwen transforming into Titan Girl as she used her Super Speed to zoom off with Katmeleon, and after freeing the Rangers and getting Max, we see him driving through the ground with the help of the Rust Bucket with Katmeleon riding inside as Titan Girl rode on top of it and Slamworm could be seen slithering underneath them underground as Fairygirl flew above them and Diamondhead could be seen surfing through the air beside her while generating monstrous and large clusters of pale green diamond crystals from out of his hands and feet to fly through the air at high speeds.

"So, we have to chase down some illegal racers?" Plumber asked while wearing his supersuit as Diamondhead nodded stoically.

"Yeah."

"Oh, okay...guys, why did you pick Diamondhead and Fairytail, then? I mean, they can fly and all, but it seems like XLR8 and Blitz would have been more appropriate."

"Mistransformation is a bitch..." Fairytail says with a pout as we see them being able to catch up with the Illegal Car Racers as they arrive at Grand Prismatic Springs and zoom past the first marker of the race.

"First marker of the race!"

"Let's get rid of some of this dead weight!" Marge and Mel said while driving their monster truck over to collide against Dirty Dobbs's Drill Machine.

"Curse you, Malachi sisters!" Dirty Dobbs screamed as his Drill Machine was sent flying over to a large bridge containing tons of innocent people.

"Oh, no you don't!" Diamondhead screamed while surfing over to land on the ground and slid across the floor as he placed his hand on the ground and created a huge wall of pale green crystal diamonds that protected the civilians and the bridge from getting hit by the Drill Machine as it bounced off of it.

"Curse you, Malichi Sisters! It's time to really go off-road!" Dirty Dobbs says while pressing a button on the dashboard as the Drill Machine then drilled itself down into the ground and disappeared from sight as the gang arrived at the geysers and zoomed past the second marker of the race.

"Ha ha! The second marker!" LaGrange says with a mocking laugh as he and the others can be seen dodging and weaving through the active geysers.

"These busters think they can beat me?! Well, I've got something that nobody else does! I got family!" Vin says while pressing a button on the dashboard to have a bunch of metal arms pop out of his car and fly over to latch onto the monster truck of the Malichi Sisters.

"Beat it, Ethanol!" An angry Mel yelled as Vin began trying to slam their monster truck against the trees, only for Titan Girl to raise her arms and wave her glowing yellow electrified arms around to send out a wave of yellow electric wave that flew over to slash through the metallic arms, freeing the Malachi Sisters and preventing them from hitting the trees as, much to everyone's surprise, Dirty Dobbs drilled out of the ground and flew above them as he laughed maniacally.

"I'm not out of the race yet, you wash rags-Ugh!" Dirty Dobbs says with an evil grin as he is about to crash down on top of Vin and the Malichi Sisters to kill them, only for Slamworm to burst out of the ground and collide against him to slam him down onto the ground, thankfully not killing him, but the crashlanding left Dirty Dobbs heavily injured and unconscious as his Drill Machine was smashed into a billion pieces.

"Huh, what good luck. For a minute there, I thought I was going to-,"

"Mechanae Discombobulus!" Fairytail chanted while raising her glowing pink hands as she fired dual beams of magical pink energy that flew over to collide against Vin's car, instantly dismantling the vehicle into a billion pieces as the only thing that remained was the driver's seat as Vin slid across the ground before stopping as he unlocked his seatbelt and stood up from his seat and placed his hands on his hips with a small smile on his face.

"Good thing I was wearing my seatbelt."

"Appendage-A-Regoria!" Fairytail chanted while raising her glowing pink hands as she fired dual beams of magical pink energy that flew over to collide against Vin's body and instantly magically paralyzed him. "Stay here long enough until the Police arrive," Fairytail says to a magically paralyzed Vin as she then flew off.

"This is getting serious! We need to stop these idiots before they destroy Yellowstone National Park and kill everyone!" Plumber says with a serious glare as he and Titan Girl drive up to a flying Fairytail as Diamondhead flies onto the scene, and Slamworm appears after making sure that the authorities would be able to apprehend Dirty Dobbs while he was gone.

"Yeah, and if we don't beat them to the treasure-,"

"Treasure?" A suspicious Plumber asked while eyeing Diamondhead sternly as he sweated nervously.

"Oh, uh-,"

"Benji means that the park is a national treasure!" Fairytail interrupted as Slamworm nodded.

"And LaGrange and his goons need to be stopped!" Slamworm says as Max grows angry.

"Grrrrrr, LaGrange!" Plumber says with the camera zooming in on his eyes briefly before zooming out as Katmeleon cheers loudly and the Bio-Team continues chasing after the Malachi Sisters and LaGrange as they reach the mud pots and zoom by the third marker of the race.

"Looks like you're not so fast after all, Le Grunt!" Mel says as LaGrange grinned slyly.

"Ah, but I'm only toying with you two, Malichi Sisters!" LaGrange says while zooming forward as he laughs evilly. "And now, for the coup de grace!" LaGrange says while pressing a button on the dashboard to fire out multiple missiles from out of the back of his car as they all zoomed down at the Malichi Sisters, who drove around to avoid the missiles as Diamondhead, Fairytail, and Titan Girl raised their hands to fire out a bunch of pale green crystals, pink magical energy beams, and bolts of magical yellow lightning that collided against the missiles to blow them up in mid-air.

"Man the gun! Time to show him who's boss!" Marge ordered Mel, who nodded as she got out of the monster truck and climbed it to man the automated machine gun planted on top of their vehicle.

"Ew, Titan Girl, what did you eat today?" Diamondhead asked with a mischievous smirk on his face as an embarrassed and blushing Titan Girl turned to him.

"That's not me! That's the sulfur smell from the mud!"

"Whatever! It's okay, though, all your stinking has got me thinking about flying!" Diamondhead quipped as Fairytail and Slamworm realized what he was planning and nodded as they reached up to slam their hands into their Biomnitrix Symbols and Nemetrix Symbol as dual flashes of green lights and a flash of purple light occurred as Rook Shadow Quick Change back into his Normal Form and quickly activated his Omnitrix before slamming his hand down on it as a flash of purple light rang out, and we see the trio Quick Changing themselves into-

"Stinkfly!" Stinkfly screamed as he flew ahead. "One big order of goop, coming right up!" Stinkfly says while raising his pedunculated pretty small green eyes as he spits out four streams of green slime that flew over to attach themselves to the automated gun on the Malichi Sisters' Monster Truck and Mel as she got slimed up.

"What in the-You're getting in the way of our treasure!"

"Hey, that treasure is mine!" Stinkfly says while flying over to grab a slimed-up Mel and flew her away.

"Hey! Put me down!"

"Vortex!" Vortex shouted while flying forward as she raised her hands and created a large white tornado underneath the Malachi Sisters' Monster Truck as it was sent flying up into the air.

Once the flash of purple light died down, we see that Rook Shadow had now transformed into a 5'2-feet-tall Male Citrakayah as he resembles a feline-like alien with eyes that have purple scleras and black cat-like slit eyes, no hair/ears, a triangle-shaped nose, a small mouth with black lips and has an underbite as he also has a pair of white fangs, a sharp chin, a pair of four-fingered clawed arms with retractable black spike-like blades, Purple Fur, a tall slim build, a long purple cheetah-like tail with black stripes on it, a pair of three-toed legs with retractable black spike-like blades, and his outfit consists of a pair of large black spiky mask that covered his eyes, a short-sleeved black jumpsuit with purple cuffs and a big purple thunderbolt-like symbol planted on his chest, a pair of fingerless black gloves, a purple belt with the Omnitrix Symbol planted in the middle, and a pair of purple boots that exposes his toes. His name is-

"Fasttrack!" Fasttrack yelled while zooming forward as he used his afterimage trail to create a platform of purple/black energy that allowed him to run up into the air and zoom over to burst through the door of the airborne monster truck as Rook Shadow grabbed a frozen and screaming Marge as he then zoomed down to land back on the muddy ground and skid to a stop in front of the others as Stinkfly raised his pedunculated pretty small green eyes as he spits out four streams of green slime that flew over to wrap around the Malichi Sisters to tied them up with green slime together and Plumber and Titan Girl appeared as Vortex turned to them.

"Can you guys handle these two? We have to hurry and catch up with...LaGrange!" Vortex says with the camera zooming in on her eyes briefly before zooming out as Titan Girl nods.

"You can count on us, guys." Titan Girl says as the trio nods and turns around to either fly away or zoom ahead. "Wow, Bio-Man, Bio-Girl, and Rook are really on their game today."

"And so selfless too. Putting their love for Yellowstone first." Plumber says as we cue back to the others and we see them making their way through the mud pots with greedy looks on their faces.

"Looks like they're all out of sight, and I was looking forward to a good challenge!" LaGrange says with a sinister laugh until he notices a couple of familiar people and a new person flying/running after him as his jaw drops in shock and anger. "What?! No, it can't be! Is that-,"

"License and registration, please!" Stinkfly says while he and Vortex flew over to float by the left side of his car as they laughed amusedly.

"But, seriously, pull over, and if you wouldn't mind handing over that treasure map, we would gladly appreciate it!" Vortex says with a sly grin on her face as she floats in mid-air in a relaxed position.

"Buzz off, you alien freaks!" LaGrange yelled angrily as he then zoomed ahead.

"Fine! I guess we'll do this the hard way!" Fasttrack says with a smirk while popping out his retractable black spike-like blades as he zoomed forward in the form of a purple/black blur and ran around LaGrange's car to slash apart his tires as the vehicle began spiraling around, out of control.

"Surely you don't think that will stop...LaGrange!" LaGrange says with the camera zooming in on his eyes briefly before zooming out as he then pressed a button on the dashboard and his slashed-up tires were replaced with new ones as he zoomed ahead.

"Oh, wait till we catch up, you're gonna-," Stinkfly says with a glare just as his and Van's Biomnitrix Symbols began beeping negatively as they Timed Out back into their Human Forms with dual flashes of red light as, thankfully, Fasttrack zoomed over to raise his hands and catch Ben and Vanessa in his arms.

"Thanks for the catch, Shadow." A grateful Bio-Girl says with a smile as Rook Shadow nods.

"Now, it's time to get that treasure!" Bio-Man says as the others nod and Fasttrack rushes ahead as, after a few seconds of running, they are able to keep up with LaGrange, who arrived at the abandoned cavern as they zoomed over to stop in front of him and Rook Shadow places the lovebirds down onto the ground just as his Omnitrix Symbol beeped negatively as he Timed Out back into his Normal Form with a flash of red light. "Hey! The race isn't over...LaGrange!" Bio-Man says with the camera zooming in on his eyes briefly before zooming out as LaGrange scoffed and rolled his eyes.

"I assure you, this race is already won," LaGrange says while pressing a button on his car to open it up and the trio is shocked to see the Illegal Race Car Driver riding around in a Go-Kart as he proceeds to zoom into the abandoned cavern and a glaring Ben and Van glanced down at their Biomnitrixes and were happy to see that they got an instant recharge as they raised their arms and slammed their hands down on their alien devices as Rook Shadow did the same with his Nemetrix and triple flashes of green and purple lights rang out as, once they died down, we see them transforming themselves into-

"Overflow!" Overflow screamed while lowering his arms and firing dual streams of water that sent him flying up into the air as he made his way into the abandoned cavern.

"Mermaid!" Mermaid shouted while going over to dive into the water placed in the abandoned cavern and began swimming ahead as she now had her messy straight dark green hair that reached down to her shoulder blades tied up into two low-hanging pigtails, a single black shoulder pad with the Biomnitrix Symbol attached to it as it had a purple cloth that hangs down and connects with her purple loincloth as it stretches down to her feet and had two thin black lines that have a zig-zag pattern that points upwards, no shoes, and a pair two black/purple tubes that are filled with water as they are strapped onto her back and it connects to a small black/purple collar that is wrapped around her neck, supplying her with water.

Once the flash of purple light dies down, we see that Rook Shadow has now transformed into a 6-feet-tall Male Coleopterian Macrocorvus as he resembles a giant crow as he has a bone crow-like head with large pupilless purple eyes, two holes that act as a nose, a small mouth underneath a huge amount of puffy black feathers that also had a bone-like necklace, a trail of large spiky bones that runs from his head down to his back, a pair of huge black feathery wings with two long spiky bones protruding out of them, gray skin on his chest and legs, a long black feathery tail with a trail of spiky bones planted on it, and a pair of three black claws toes with a single black clawed toe planted on the back of his legs as he has the Nemetrix Symbol planted on his chest. His name is-

"Crow Reaper!" The Now-Named Crow Reaper exclaimed through the communication system placed inside of the Nemetrix Symbol as it beeped red every time he talked and flew ahead as Overflow briefly raised his hands to fire a bunch of streams of water that collided with the back of LaGrange's Go-Kart.

"Ugh! Good try, but not good enough to defeat LaGrange!"

"Give up! You're no match for us...LaGrange!" Crowreaper says with the camera zooming in on his eyes briefly before zooming out as LaGrange smirks evilly.

"Let's see how well you race when you're dodging these!" LaGrange says while reaching into his belt to pull out a bunch of explosives and tossing them over to the boys as Overflow merely tanked the explosions with ease as Crow Reaper shoots out several spikes that grow around his body like darts and collided against the explosives in mid-air to blow them up in mid-air as the boys flew/zoomed by a huge geyser filled with magma.

"Whoa! This isn't a cavern, this is a geyser!"

"Who would hide a treasure in a place like this?" A bewildered Crow Reaper asked before he and Overflow shook their heads and flew after LaGrange, who pressed a button on his dashboard to fire a bunch of missiles at them, as Ben quickly reacted by firing multiple streams of water that collided against the missiles and froze them up in mid-air as the Illegal Race Car Driver reared back his head and began laughing evilly.

"Ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha, ha!" LaGrange laughed maniacally as he then grinned greedily. "Just one more jump and the treasure will be mine! I am the ultimate racing champion!"

"Hey, you're Italian, right?" Overflow asked as he and Crow Reaper flew after him. "How do you say, 'You're slow!', in Italian?"

"He's actually French, Bio-Man!"

"Oh, shit, was that racist?" A worried Overflow asked just as Mermaid shot out of the water as she flew over to collide against LaGrange's Go-Kart and send it flying out of the cave to shoot into another large cave filled with magma as Bio-Girl laughed.

"Thanks for keeping him distracted, boys!" Mermaid says while landing on the ground as Overflow flies over to land beside her, and Crow Reaper floats above them as they glance over to see a panicking LaGrange hanging by a cliff and his Go-Kart crashing down into the ground as Van winces. "Okay, maybe I was a little too rough..."

"Curse you, Tennyson! Cunningham! And..."

"Rook Shadow."

"Thanks...curse you, Tennyson! Cunningham! And Rook Shadow!" An angry LaGrange yelled just as the area around them began shaking violently as large pieces of rubble fell down on top of them.

"This place is pretty unstable. We should-,"

"Guys, look! It's the treasure!" A beaming Mermaid says while pointing down at a cliff that held a treasure box that held tons of golden coins as the trio perked up, and Van went over to jump up to land on Overflow's back as he and Crow Reaper flew down to land in front of the treasure chest before reaching up to slam their hands against their Biomnitrixes Symbols and Nemetrix Symbol to Quick Change back into their Normal Forms with triple flashes of green and purple lights.

"I knew it! I knew that it was real!"

"It's so beautiful!" Rook Shadow says as he, Ben, and Vanessa reach behind them to pull out four backpacks that the Rangers had let them borrow a while back as the trio quickly began piling a bunch of golden coins into their backpacks until they were all filled up to the brim with golden coins just as the cave around them shook violently again as the magma underneath bubbled wildly.

"This place is gonna blow." Rook Shadow says as Ben nods and glances over at an endangered LaGrange.

"So, we either have to choose to get the treasure and leave or save LaGrange and leave?"

"Wait a minute, if LaGrange dies, we don't have to deal with him anymore. We could be done with him forever." An excited Bio-Girl says as LaGrange heard this and panicked.

"Tennyson!"

"Wait...can we really do it? Just...let him die?" Bio-Man asked as LaGrange gritted his teeth fearfully.

"Cunningham!"

"I mean, well, we are not the ones killing him. LaGrange is because it was his idea to go into the abandoned cavern in the first place. Not to mention that he DID try to kill us earlier." Rook Shadow pointed as LaGrange could feel his grip on the cliff slipping.

"Rook Shadow!"

"...Okay, guys, for real, are we really doing this? Because if we do, this secret will stay with us for the rest of our lives."

"AREN'T YOU THREE SUPPOSED TO HELP PEOPLE?!" An angry and concerned LaGrange asked as Ben groaned.

"Ugh, yes, we're supposed to help people..."

"Besides, Max and Gwen would kill us if they found out the truth." Bio-Girl pointed out as Rook Shadow nodded.

"Indeed. Okay, guys, here's the plan. I will steal the treasure while you guys save LaGrange." Rook Shadow says as the lovebirds nod and activates their Biomnitrixes as Ben dials up Cannonbolt while Van dials up Tricetaurus.

"It's Fusion Time!" Bio-Man and Bio-Girl exclaimed in unison as they smacked their Biomnitrixes together, and a flash of green light occurred as, once it died down, we see a Fusion of Cannonbolt and Tricetaurus standing in place heroically.

Standing before them are Ben 10 and Van 10 transformed into their New Fusion Form of an Arburian Pelarota and a Vaxasaurian as they resembled a hulking 15-feet-tall humanoid broad-shouldered triceratops-like alien with green eyes, three white horns on his head, sharp yellow teeth, a pair of huge muscular arms with three sharp black claws on each hand, his body is mostly white on his chest/abs/inner arms/lower jaw with black on his upper half as he also has natural yellow armor plating on his back/shoulders/the back of his arms/tail/arms/upper legs, a long tail with a war hammer that was attached at the end of her tail naturally, a pair elephant-sized feet, and wears no clothes as he has the Biomnitrix Symbol was located at his left breast. Ben 10 and Van 10 had now transformed into their combined Male Fusion Form of Cannonbolt and Tricetaurus named…

"Cannontaurus!" The Now-Named Cannontaurus screamed while jumping off from the cliff as he fell down to catch LaGrange just as he lost his grip on his cliff and nearly fell down to his death if he wasn't caught by the Biomnitrix Fusion Alien as Cannontaurus rolled himself into his Ball Form and crashed down into the magma below as Rook Shadow swiftly activated his Time In Omnitrix and slammed his hand down on it to transform into Fasttrack with a flash of purple light.

"Well, Maybe It's Time To Fuse Into..." Fasttrack says while reaching up to grab his Omnitrix Symbol as he presses the sides tightly for five seconds, and the core extends as it shows the silhouette of Astrodactyl. "...Fastodactyl!" Fasttrack screamed as he proceeded to slam his hand down into the core, and a flash of purple light covered his body as we see the Revonnahgander transforming into a New Fusion Alien Form and striking a heroic pose.

Standing before them is Rook Shadow transformed into his New Fusion Form of a Citrakayah and a Pterodorian as he was 4'5 feet tall and resembled a Pterodactyl, a Glider, and a feline with a sharp pointy dark purple head with a pair of small eyes that have purple scleras and black cat-like slit eyes, no hair/ears, a triangle-shaped nose, a pale purple beak-like mouth, a 'jetpack'-like structure on his back with two small black retractable wings attached to it as they resemble a glider in appearance, a pair of three-fingered clawed arms with retractable black spike-like blades, dark purple 'metallic'-like fur, a tall slim build, a long purple cheetah-like tail with black stripes on it, a pair of three-toed legs with retractable black spike-like blades, and his outfit consists of a large black spiky mask that covered his eyes, a short-sleeved black jumpsuit with purple cuffs and a big purple thunderbolt-like symbol planted on his chest, a pair of fingerless black gloves, a purple belt, and a pair of purple boots that exposes his toes as he has the Omnitrix symbol located on his chest. Rook Shadow had now transformed into his combined Male Fusion of Fasttrack and Astrodactyl named...Fastodactyl!

"I got it!" Fastodactyl says while flying over to grab the treasure chest and easily holding it up into the air before firing a big burst of internalized purple star power that enhanced his flight as he flew out of the cave through the huge hole on the top, and we cue back to Cannontaurus as we see him poking out his tail to slam it down on the ground to produce a big green shockwave that sends the Biomnitrix Fusion Alien flying up high into the air and shoots out of the cave before rolling down the huge geyser to land on the ground while unrolling himself out of his Ball Form as Fastodactyl flew down to land beside them and placed the treasure chest down on the ground as the duo reached up to slam their hands into their Biomnitrix Symbol and Omnitrix Symbol to Quick Change back into their Normal Forms with triple flashes of green and purple lights.

"Well, all righty, Sammy! That's the last of 'em." A Ranger says as she and her buddy go over to handcuff a shaken and scared LaGrange. "Lock this troublemaker up. Let's go, Mr. LayGraynge,"

"It is pronounced...LaGrange." LaGrange says with the camera zooming in on his eyes briefly before zooming out as he was then dragged over to be placed in a Police Van with the Malachi Sisters, Vin, and Dirty Dobbs as they then drove away.

"Way to go, guys. Did you get the treasure?" Titan Girl asked as Ben nodded with a big grin on his face.

"Oh, yeah, we did. Now the treasure is all ours."

"Actually, Bio-Man, since this treasure was found on Federal property, it belongs to the government."

"Uh, what?"

"Lame."

"But I wanted the treasure."

"That's dumb." Bio-Man, Bio-Girl, Rook Shadow, and Katmeleon said in unison as the Ranger nodded.

"Oh, yeah, Plumber's right, and since those guys did so much damage to the park, we can put that money towards the conservation fund." The Ranger says while she and her partner grabbed the treasure chest as they walked off.

"Isn't that lucky, kids? Everything worked out. We saved the day, captured the bad guys, and stopped them from wrecking a national monument. And along the way, you guys found the real treasure, the natural beauty of Yellowstone National Park." Plumber says as the kids give him flat looks.

"Yep, not doing it for me." Titan Girl says as Van leaned over to whisper into her ear.

"Don't worry, we were able to steal a lot of the treasure and packed it into our four backpacks," Bio-Girl says as Titan Girl perks up and shares a hug with her while Bio-Man and Rook Shadow share a high five as an oblivious Max eyes them confusedly.
