Ben 10 Ultimate Summer EP 13: The Beast Inside

I don't own anything except my OCs.


Intro:

A green glowing, steel pod was flying through space, hurtling towards earth as it crashes, making a huge green flash.

The camera zooms out from the glowing symbol on the Ultimatrix as Ben looks up close at it.

He then activates it while smirking at the camera, raising his hand high and slapping it down on the core.

The background turns all green as Ben morphs into Four Arms, who pumps his upper fists while cracking his lower ones with a smirk.

A white number appears on the left side, starting at 1.

"Ben 10!"

2: Heatblast ignites 2 fire balls in his hands.

"Ben 10!"

3: XLR8 zooms into the right.

4: Diamondhead swaps his right arm across as it turns into a blade.

"Ben 10!"

5: Cannonbolt uncurls and poses.

"Ben 10!"

"Ben 10!"

6: Upgrade stretches out of his puddle form.

7: Grey Matter hops off the 7 and lands into a crouch, giving a thumbs up and a smile.

"Ben 10!"

8: Water Hazard slides in on his water blasts and raises his fists up.

"Ben 10!"

9: Wildvine extends his legs and stretches out his right fingers while holding seeds in his left one, chucking them offscreen.

10: Big Chill phases through the number and floats briefly before zooming near the camera.

"Ben 10!"

Big Chill's head turns back into Ben's as it rotates.

The camera zooms out to reveal Max and Gwen by his side.

Ben gave a low-five as his grandfather as Gwen crosses her arm and shakes her head playfully with a smile.

The 2 then ran off-screen, making Ben run towards the camera with a determined look.

He then froze as his aliens appear in heroic poses on each of the kid's sides, 5 on each side. Just as the title appears in a black background with green rays appearing from the title.


"AAHHHOOOOOO! GO STATE RED WOLVES! Good to be back, isn't it, kids?" Max asks the 2 as they arrived back at Max's old college for a festival. "Yeah. More time at the library. Or more stuff you did in college." Ben answers in boredom as Gwen adds in. "Yeah, I mean, the thing with the goldfish? BLEAAGHH!" "You can skip the library this time! My buddy, Lester has invited us back to see the rare animals of the tour in the Quad." Max explains as he hands a poster to the kids. They both see an advertisement for the rare animals, getting their interest. "You mean, like a zoo?" Ben asks as Gwen adds in. "Maybe the rare animal professor can explain why you act like a beast all the time?" The boy frowns at the girl at the jab.

"AAH-HEM!" The kids turn to their grandfather. "It doesn't open for an hour. I'll go find Lester and get tickets. Meet me back here in an hour and have fun." The man said as he walks off while the kids went to the exhibit to check it out.


The kids walk towards a bunch of tents as some students were busy hanging out, practicing or studying. "Think this is it?" The boy's questions were answered when a bunch of people ran out screaming. A hairy, muscular fist bashes on the ground from the tent as a humanoid-like hyena beast with red eyes and ripped short roars out while pounding his chest.

"COOL! Now this is more like it! This zoo is more fun than I thought!" Ben exclaims as Gwen looks confused. "There's nothing on the flyer saying about rare animals attacking visitors." Gwen said as the beast corner a man hiding behind a trash can. The beast knocks the can away as it lands near the kids. "Okay, Bobo! Time for some obedience training!" Ben exclaims as he slaps on the watch, morphing into Upgrade.

"Oh, sure! Upgrade is totally what I want! I can make this work! It's not like I wanted Diamondhead or anything." Gwen was unsure but didn't have time to worry about it as the beast was chasing more people and was attacking a tent. "Okay! Make it work! Make it work!" The alien said as he tries to find some tech to use, only to come across a cart driven by a guard. "Not a laser blaster, but it will do!" He grabs the cart, making the guard scream out in shock. "Excuse me, need to borrow this!" He apologizes and merges with it and turns into a small bulldozer with rocket boosters. He shot forward at the monster, ramming it into a cage as it shook it's head from the impact. "Okay, Fuzzy! Back into the cage with you!"

But the beast punches the ground and stops, tossing Upgrade into a couple of cans as he then recovers and turns into a puddle, slipping under the beast and coiling around it as the monster struggles to break free. "Give it up, dude! The more you struggle, the more I-" The beast roars out as he burst out in a display of stretch as Upgrade was separated into parts, only to pull himself back together.

He then tried his eye beam, but the monster was faster and dodged them as it ran up and tackled Upgrade, sending him flying onto his back as he recovers and punches it off. He then melts into a puddle to avoid another claw swipe as the alien quickly counters with a surprising uppercut. Upgrade then times out as he notices. "Whoa! Not good!"

"Ben!" Gwen called as she ran up to him as the boy backed away. The beast approaches the kids as Gwen steps in front with her arms spread. "Don't hurt my cousin!" The beast was about to attack her when he stopped suddenly. It then looks at the girl in curiosity as the tween girl looks at him closely, notching something off as she gets a closer look. "Wait a minute… I think there's a person in there!" The beast continues staring at her, until he shakes his head and holds it, roaring as he bolted off as Gwen drags her cousin. "Ben! We got to follow it!" "Hey!"

Both kept looking until the girl saw an open door. "THERE!" They ran up, only to gaze at the claw marks around the door. "Are you sure that thing is human? Because it needs some nail clippers!" Ben comments at the marks as Gwen quickly shushes him. "SHHHH!" She points at a laundry basket with something shuffling around it. They pull the sheet off to see Max's buddy, Lester with torn clothes. "LESTER?! JINX! YOU OWE ME A ROOT BEER!"

"What are you doing in there?" Gwen askew as the elder answers. "I'm sorry about before. I don't know what happened! I was setting up the exhibit when a strange man was taking samples from the animals and putting them in some sort of science device. I tried to stop him, but he turned and fired a beam at me! It turned me into an animal! It was like I forgot who I was." Lester explains as the 2 cousins look at each other in thought.

"Until you saved me." Ben grins as he brags. "It's no biggey. Just some alien help and—" "No, not you! You." Gwen realizes he was talking about her. "Really?" "Oh, man!" Ben groans out. "You remind me of my sister when she was young. You snapped me out of it." Gwen helps the elder out as Ben points out. "Anyway, you know who that strange man sounds like?" "ANIMO! JINX! YOU OWE ME ANOTHER ROOT BEER!"

They left the room as Lester went somewhere to rest as Ben mockingly said. "It's really awesome that you fought that animal. Oh, wait, you didn't. Because I was the one who did!" "Put a sock in it, Ben! We have bigger things to worry about! Such as Dr. Animo being here and planning to do something with the rare animals." "Guess you're right." Ben ponders out

She then saw a vet hospital van in an alley. "Speaking of the problem." They both went up to it and in it, amazed by the lab inside. Ben saw a blueprint and read it. "'DNA converse module?' 'Rabid cell growth stimulation unit?' 'Genetic fusion stabilizer?'" The boy puts his head in confusion from the unknown words, having no idea what they mean or do. "Remind me to pay attention in science class, when we get back to school!" "Pay attention to this." Gwen holds a picture up as they both look at it, seeing an old man with picture of a dog and girl as a kid next to him looks in awe. They both look at the boy, finding him familiar.

"Is that Dr. Animo?" "I think he was just Aloysius Animo when this photo is taken. That man next to him must be his father." Gwen answers as Ben made a mocking face at the photo. "Looks like he takes after his dad, science-wise. And ugly wise too! BLEAAAGGGHH!" Gwen chuckles as she snaps her finger in amusement. "This is Animo's mobile lab. But where's Animo?" They both realized where the madman could be. "THE RARE ANIMAL EXHIBIT! JINX! YOU OWE ME YET ANOTHER ROOT BEER!" "Quit doing that!" "I will when you stop it!" Ben argues back with a frown.


They both ran towards the tent, only to be stopped by a guard. "Sorry. The exhibit is closed! Some sort of animal on the loose." "Uhh… It went that!" The boy points as the man ran off. "That actually work?" Ben shrugs in response at Gwen as they venture in, amazed by all the exotic animals on display. As they kept walking, the boy told Gwen. "Okay, if thing get hairy, just stay out of the way and let me do my alien hero thing." "WHAT?! You would be monster chow if it wasn't for me!" "Look! I'm the only with the powers, it should be me handling the mad scientist, okay?" As they turn a corner, they gasp to see Max, bound and gagged as he mumbles at them. "GRANDPA!"

"HAHA! Ben and Gwen Tennyson! I heard you encountered my new specimen. I think my version of Lester was quite the improvement, don't you?" Dr. Animo said as he steps out from behind a cage. "LET MY GRANDPA GO!" Ben demanded out loud as Animo replies. "Of course! After I used him to demonstrate my creation! For years, I worked on my Transmutatior ray. But after seeing your watch in action, I tried something new: The Animerger! It mixes the rare animal DNA With the DNA of my targets and brings out their wild side." "So... it's just a cheap knockoff of my gauntlet?" Ben ponders out. "It is not a knockoff!" Animo cries out.

"Wait! You're turning people into monsters!?" Gwen cries in shock as the madman corrects her "ANIMALS! Under my control! Perhaps you would like to see it on my new test subject." He said as he takes out his ray gun device as he looks at Max, making Ben slap on the watch and turns into Heatblast. "Take this!" He tosses a fire ball that knocks Animo away, making him return fire as the alien leaps out the way as Gwen hides behind a fish tank. "You're not adding more freaky animals to your Zoo, Animo!" He kicks him into a ape cage as he aims his gun. "My invention is the future!" He fires as Heatblast dodges.

"My genius will not be denied by some kid with a fancy alien device!" He cries out as he fires, making the alien dodge and attacks at close range. He knocks the gun out of his hand and pushes him aside, going to grab it when Animo pushes a tank filled with fish and water to douse the alien, but Heatblast was quicker and dodges out of the way.

"Time to take your blaster away!" He picks it up and intense his fire, making it glow red as it melts. "Too bad! It was this year's hottest toy!" Heatblast smirks, but just then, red energy starts sparking from it Animo got worried. "My creation!' "Ben! That Animerger is—" "Melting? That's the idea!" "No! it's exploding!" Heatblast notices what Gwen is saying and quickly widens his eyes socket while throwing it away, making the mad scientist try to get it. "NO! Don't let it hit the—" BOOMMM The blaster exploded, engulfing Animo in its light as he mutates.


His arms became gorilla arms with claws as his bottom half turned into the body of a wolf as 2 tentacles burst from underneath his arms as his head became a lion's with the sides of its mane white while the rest of it it's a darker grey. His red became red and silted with a gorilla's torso.


The mutated Animo roars loudly as it beats his chest. "WHOA! Here's the walking zoo!" Heatblast comments as the beats roars and attacks him, knocking him away as he retaliates with a flamethrower. The beast blocks as it was pushed back. The stream dispelled as Heatblast attacks with fire fists while one of his tentacles grabs his arm. "Oh no you don't!" He flares his body and burns the limb, making it howl in pain before growling at him, only to get kicked by a flaming leg as Heatblast back flips from him.

"I think you're making the beast in him upset!" Gwen calls out. "Well, let me know if you have a better idea!" He was tackled by the monster, making him struggle with it as Gwen calls out. "Here, creature, creature!" She got the monster's attention as she ran out of the tent with it following her.


The 2 runs inside the football stadium, but Gwen trips and falls, making the beast tower over her and snarls until it got knocked away with a fireball. The girl sees Heatblast with 2 flaming orbs in his hands. "Hey! Ugly! Come and get a hot meal!" He chucks the orbs at the monster, who ducks. The monster charges and punches, only for the alien to flip and kick over him. The alien then made a fire cyclone and unleashes it on Animo, dealing some damage to it.

Heatblast charges and rocket tackles him, smacking Animo into a wall. Heatblast punches him while he's down, only for the tentacles to grab and toss him away as he slides on the ground, only for Animo to leap up and slams his arms down on him, punching him over and over and then grabbing him and tossing him into a wall as the alien slides down and groans. "And I thought Animo was a real pain when he was human!" He got blindsided and fell on his back, flipping up and attacking again. Gwen realizes something at the word 'human', flashing back with Lester earlier as she recalls how he was able to snap out of his beast state.

She gasps in realization. "Ben! We need to remind him that he's human with something he cares about!" "But what could he possibly care about?! This is Animo we're talking about!" Only for the alien's eyes widened as he realizes there is something Animo cares about! "THE PHOTO! JINX! STOP DOING THAT! AND YOU OWE ME A 4TH ROOT BEER!"

"Okay, you keep Animo distracted while I get the picture!" Gwen ran back to the van as Heatblast keeps fighting. The beast roars as it charges, making the alien hero propel himself over it and lands as the monster turns around. He then creates a circle of fire to box the creature in. "Anytime now, sis!" He quickly blocks with his arms as Animo leaps over the fire and punches him, knocking him on his back, again. "Come on, Gwen!" He groans out.

"I got it!" The girl runs back with the frame as Heatblast knocks the monster back and runs towards her and yells out. "NOW! NOW!" BEEP BEEP BEEP BEEP Gwen tosses it as Ben changes back, making him grab it and shows it to Animo as he charges. "LOOK AT THIS!" The boys scream out as the monster stops and stares at it.

"That kid. That's you, Dr. Animo! Doesn't that man mean something to you? Isn't he your father?" Ben questions as the beast got a sad expression, remembering something as he changes back into a human with shredded clothes. "He's human again!" "Well, mostly human." Ben adds to his cousin as the man looks at the older person in longing.

"You're right. Apotheoses Animo. He was my father. The finest Veterinarian who ever lived." The boy looks at the photo in response. "All my life, I tried to live up to my father's legacy. The Animerger was my best creation. AND YOU RUINED IT, TENNYSON!" The kids flinched as the mad man yells at them with rage while two guards show up and restrains him. "YOU RUINED IT!" "All right, buddy! That's enough!" They drag him off as Animo cries out. "I WILL HAVE MY REVENGE!"


Ben unties Grandpa as he stands up and cracks his back. "Ahhh... Nice work, kids!" "Yep! Nothing a couple of aliens can't handle." Gwen coughs at Ben as she looks at him with scorn. "'sigh' And a cousin with a good brain helps, too." Max rubs his hands together in excrement as he looks around. "Whelp! How about it? Ready to see those rare animals?" The kids got a fearful look as they said together. "NO THANKS! JINX! YOU OWE ME A 5TH ROOT BEER AND WILL YOU KNOCK IT OFF WITH THAT?!" Max groans out as he facepalms.
