Chapter 2:Ivysaur's Mysterious Tower!

The next morning in the Cerise Laboratory, Ash, Goh, Ben, Gwen, Kevin, Rook, and Julie now greeted their first morning here. As the alarm clock rings, none of them are wanting to wake up. ''Guys, it's morning.'' muttered Goh.

''Yeah...we have to wake up.'' agreed Ash.

''5 more minutes.'' said Ben in his sleep.

''Agreed.'' replied Rook.

''I'm still tried.'' moaned Kevin.

''Girls, more of their beauty.'' groaned Gwen.

''Yeah.'' agreed Julie.

And just then Mimey walks into the room as he use the mime vacuum, which suddenly takes away their blankets, and Ash also falls to the floor with shock.

''Ash? Are you are okay?'' asked Goh while he, Ben and the others are fully awake.

''Oh, it's just Mimey.'' answered Ash.

Once they clean themselves up, they are now in the dining room as they are in awe at the sight of food.

''Can we really eat as much as we like?'' inquired Ash.

''Of course, after all, we're research fellows here.'' answered Goh.

''Yeah, being a research fellow is amazing.'' responded Ash. ''And they also got Pokemon food as well!'' he added.

''Pikachu, Ship, Zed and Charmander are happy as they also take a bowl of the food, and then they all sit at the table as they have their breakfast. Ash, Goh, Ben and the others together.

''Man, the food here is good.'' said Ben.

''Right you man.'' agreed Kevin.

''Indeed.'' nodded Rook.

''I can't wait today.'' stated Julie.

''Yeah, today we are research fellows.'' reported Gwen.

''I can't wait to checked the Pokemon here.'' smiled Ben while the others nodded in agreement.

''Oh, you guys are love the Pokemon.'' remarked Ash.

Then they saw Professor Cerise and Chloe also coming in.

''Good morning.'' greeted Professor Cerise.

''Good morning, and you too, Chloe.'' greeted back Ash.

Yamper goes with Pikachu.

''Did you guys sleep well?'' questioned Professor Cerise.

''Perfectly.'' answered Goh. '

'You even have a buffet in the lab, that is the best!'' added Ash.

Chloe turns to Yamper. ''Yamper, I'll put your food and water here.'' she said.

After putting the bowls for Yamper down, she takes only a bag of candies before leaving.

''Chloe, you should eat with us as well.'' replied Ash.

''I already ate. And I don't want to be for school.'' responded Chloe as she closes the door.

''Well, I'll see you later.'' said Professor Cerise. then he also leaves.

Ash and Goh looked at each other.

''So what do you think we should do today?'' asked Goh.

Ash thinks for a while. ''How about we got Pokemon capturing?'' he suggested.

''That will be nice I'm can my first Pokemon.'' smiled Goh.

''But first, let's finish our breakfast before we can to the lab.'' said Ben.

Everyone else nodded in agreement as they quickly ate their breakfast, with Mimey Pikachu, Ship and Zed doing the same.


In the lab, Ash, Goh, Ben, Gwen, Kevin, Rook, and Julie are waiting as Ren rushes inside. ''Sorry that I'm late! The bus got stuck in traffic...'' he breathed.

''Oh, that's right. I haven't introduced you yet.'' admitted Professor Cerise.

''I am Ren, I am an assistant here.'' introduced Ren.

''And my other assistant.'' Professor Cerise looks at the female worker.

''I'm Chrysta.'' she turned and introduced. ''That cause of the traffic jam is up on the news sities.

Ben and the others are looking at the screen and they see a group of Ivysaur. ''A city-wide outbreak of Ivysaur?'' asked Goh.

''Let's guess they evolved from Bulbasaur?'' guessed Ben.

''Yeah.'' answered Ash. ''First Bulbsaur to Ivysaur and finally to Venusaur.''

''Bulbasaur, Ivysaur, Venusaur. Tured to the ''saur' in the names, they're full of mysteries.'' said Professor Cerise.

''How about we go investigate?'' Ash asked the others who nodded.

''This'll be our first job as research fellows at the Cerise Laboratory!'' proclaimed Goh.

''We'll learn about Pokemon.'' said Ben.

''Indeed.'' nodded Rook.

''Right with you, Ben.'' agreed Kevin.

''Researching is the best way.'' smiled Gwen.

''You right.'' agreed Julie.

''By the way, do you Ash do have a smartphone?'' asked Professor Cerise. Ash was confused. The Professor take out one for him and it was orange and Goh already have his out.

''Thank you.'' greeted Ash.

Just then Professor Cerise sends out two Rotom.

''Rotom? Don't tell me it is another one of those Rotom Pokdex like things?'' wondered Ash.

''It seems like you have experience with it.'' realized Professor Cerise.

''Of course, I had one while I was with Professor Kukui back in Alola.'' explained Ash.

Then two Rotoms go into their smartphones. ''They are called Rotom Phones, they have Pokedox functions as well.'' explained Professor Cerise.

''Thank you, Professor.'' reported Ash.

''So Pokedox have information about Pokemon in every Region?'' asked Ben.

''Yeah, when kids around our age become Pokemon Trainers they get their Pokeballs and Pokedox.'' answered Ash.

''It's a small computer.'' commented Gwen.

''Indeed.'' agreed Rook.

''Yep.'' smirked Kevin.

''Oh by you 10 there some new research fellows are joining today.'' inputted Professor Cerise.

''New research fellows?'' asked Julie.

The Pokemon researcher nodded. ''You may come in now.'' he called out.

Then the door of the lab opened and walked in are Brock, Misty, May, Max, Dawn, Iris, Cilan, Serena, Clemont, and Bonnie.

''Hey, I'm Brock full time Pokemon Doctor.'' introduced Brock.

''Good you to see you Ash.'' smiled Serena.

''Still, acting like a little kid, I see.'' teased Iris.

''It's good for us to be together again.'' commented Clemont.

''Hey, Pikachu.'' Bonnie was petting Pikachu. Pikachu was playing with Dedenne and the two Electric Types were happy to see each other again.

Alien Force and Goh walked over to them as well.

''These guys old friends of yours, Ash?'' asked Ben.

''They're sure are, I'm use to travel with them.'' answered Ash.

''That's cool.'' smiled Goh.

''So, are these your new friends?'' inquired Brock.

''Yep, I'm Goh actually me and Ash went to Professor Oak's summer camp together.''

''Oh, I'm went to summer camp with you guys, too.'' remarked Serena.

''Oh, yeah you're Serena the girl with the straw hat.'' grinned Goh. Both Ash and Serena laughed.

''By the way, who are they?'' questioned Misty pointing to Ben and his team.

''I'm Ben Tennyson.'' introduced Ben then the alien hero pointed to others. 'This is my cousin Gwen Tennyson, my girlfriend Julie, and our friends Kevin Levin, and Rook Blonko.'' he introduced his team. ''And this is Kevin's dog Zed and Julie's dog Ship.''

''Nice to meet you.'' greeted Gwen.

''Greeting.'' smirked Rook.

''Same here.'' waved Kevin.

''Hi.'' reported Julie.

''Ship Ship.'' chimed Ship.

Zed just glowed.

''Me and Goh met them yesterday.'' said Ash.

''Nice to meet you too.'' responded Dawn.

''Same here.'' waved Cilan.

''Anyway, let's go investigate the Inysaur.'' said Ben.

''Right.'' replied everyone else they are leaving to investigate.


The group is walking on the streets searching for the Ivysaurs. Ash and his old companions were catching up.

''So, what you guys been doing?'' asked Ash.

''Well, I'm finished with my training of becoming a Pokemon Doctor and now have I finally got my license.'' said Brock.

''My sisters became back from their trip, they're leading the gym for now and I'm can go and catch some Water-Type Pokemon.'' replied Misty.

''I contested Pokemon Contests in Sinnoh, and won my first ever Grand Festival.'' inputted May.

''I contested Pokemon Contests in Johto and won the Festival.'' responded Dawn.

''And I won in Hoenn.'' stated Serena.

''Whoa, good job you three. I'm finally my Pokemon League ever!'' exclaimed Ash.

''Wow, congratulations Ash.'' smiled Max.

''I'm managed to defeat Alder and Unova's new Champion.'' replied Iris.

''So what brings you guys here?'' asked Ben.

''Well, here a brand new search laboratory was opening up.'' explained Cilan.

''They also were looking for some research fellows.'' added Clemont.

''Then we all came together here and decided to research fellows.'' finished Bonnie.

''This gonna great traveling together again with yous!'' proclaimed Ash.

''It's sure is.'' agreed Brock.

''This gonna fun, here guys.'' Ben told his teammates.

''Right with you, Ben.'' grinned Kevin.

''I'm agreed.'' replied Rook.

''I can't wait.'' responded Gwen.

''Me too.'' agreed Julie.

Goh was looking at his Pokedex. ''This is weird. I know it should be around here somewhere.'' he moaned.

''Maybe I should have this guy to help us.'' said Ash as he throws a Pokeball, a Bulbasaur appeared.

''Bulbsaur.'' chirped Bulbasaur.

''Whoa, a Bulbasaur!'' cheered Bonnie.

''Hey, Bulbasaur.'' greeted Brock

''How, it been?'' asked Misty.

''Good thinking, Ash.'' compliance Clemont

''Bulabsaur, does evolved into Inysaur.'' nodded Cilan.

''Ash, I didn't know you have a Bulbasaur.'' responded Serena.

''Well, I've been having him since I first started my journey.'' he explained. ''Okay, Bulabsaur, please us find the Inysaur.'' he ordered.

Bulbasaur flinched at the name, but he nodded as Ash and the others followed him.

Just then, the group heard a voice and it belonged to Officer Jenny. ''Please stop!'' she yelled.

''Over there.'' spoke Ash as he and the others rushed towards Officer Jenny. ''Officer Jenny!'' he shouted.

''Is there a problem, Officer?'' inquired Rook.

''Right before your eyes.'' answered Officer Jenny.

Just then, a horde of Inysaur is walking along the street, and Bulbasur is looking at the horde in awe. Goh uses the chance to scan the Pokemon. ''Inysaur, the Seed Pokemon. A Grass and Poison type. The stronger the sunlight it absorbs, the stronger this Pokemon becomes and the larger its flower bug grows.''

''I wonder where all the Inysaur are going...'' wondered Goh.

''This might not have anything to do the Inysaur, but look at this.'' Officer Jenny showed them a group of trio.

But Ash, and his old companions recognized them. ''Team Rocket?'' they asked.

''Those guys again? When will they give up?''

''I read about them on the net.'' imputed.

''Who's Team Rocket?'' asked Ben, confused.

''They are part of an evil organization whose's goal is steal and captured rare Pokemon all over the world.'' answered Ash.

''They've been trying to our Pokemon too.'' stammered May.

''And other people too.'' added Misty.

''Sounds like a group of criminals to me.'' stunned Ben with his arms cross his chest.

''Indeed.'' agreed Rook.

''These guys like the Forever Knights.'' commented Kevin.

''Yep.'' agreed Gwen.

Julie nodded in agreement.

''Okay, you kids take care.'' spoke Officer Jenny as she leaves.

Bulbsaur suddenly notices something as he rushes to a wall, with the others following suit. They find an Inysaur tackling a wall.

''What's wrong?'' asked Ash.

''It seems like it wants to get that wall.'' noticed Goh.

''But why?'' wondered Max.

''I don't know.'' shrugged Bonnie.

Bulbasaur decided to help it out, after communicating, Bulbasaur told him to use Vine Whip, and then both got past the wall. ''Nice work, Bulbasaur.'' smiled Ash. Then he returned his Bulabsaur to his Pokeball.

Then everyone climbs through the wall, they notice a giant building.

''Rotom, what is that?'' demanded Ash.

''That's a Pokemon Gym under construction.'' answered Rotom.

''Vermilion Gym, huh? It really brings back old memories.'' said Ash.

''It's sure does.'' agreed Brock.

''Yep.'' nodded Misty.

Before anyone can talk some more, they see that the Ivysaur is leaving, so they quickly follow the Grass and Poison type Pokemon and they also smell something.

''Is that Inysaur using Sweet Scent? It smells good.'' grinned Goh.

''It's smell so good.'' smiled Gwen.

''Yeah,'' agreed Julie.

''Maybe Inysaur might be going there to evolve.'' suggested Cilan.

They follow the wild Pokemon.

''Them letting out a sweet scent from their bud-like that is a sign that they're about to evolve and have their flowers bloom!'' stated Max.

They continued to follow and they saw more of them appearing, with Bulbasaur also joining in the Ivysaur horde. ''What is special about the place?'' Ash asked Rotom.

''There is a photo from when construction was starting.'' It shows a photo of Machop working with the builders. ''Before the construction began, it was a sunny grassland! Wilkd Bulabasaur and Ivysaur would gather there to bask in the sun!'' it explained.

As they arrived at the construction site, the Pokemon are clearly beaming sun overhead spurs the Grass-Type Pokemon into action, and they scale the scaffolding with their Vine Whips.

''Are they climbing up, since the sun shines bright up too?'' asked Dawn.

''Maybe we should follow them as well.'' said Ben.

''Great idea!'' agreed Goh.

Then Ben activated his Omnitrix and scrolled through the holo-ring playlist of aliens Brock, Misty, May, Max, Dawn, Clian, Iris, Clemont, Serena, and Bonnie were looking at the superhero. Ash and Goh knew Ben was doing.

''Hey, Ben?'' began Iris.

''What you doing with that watch on your wrist?'' asked Clemont.

''Something's real cool.'' smirked Ash.

''Yeah.'' nodded Goh.

''Something cool?'' asked Bonnie.

Ben nodded and reported. ''Well you see me and my friends have powers.''

After finally the icon he selected the faceplate slides opened and he slammed the dial down he was engulfed in a flash of green blinding Ash and his friends who shielded their eyes. When the green light died down the Pokemon Trainers were shocked by experts for Ash and Goh.

Standing in Ben's place was a red humanoid manta-ray-like alien with green eyes, black outlines on his face, yellow horns extending from his nose, gills underneath his arms, yellow pategia which he uses to fly and glide through water, and two lighting bolt-like stripes coming down from his shoulders. He wears the Omnitrix symbol on his chest.

''Jetray!'' he shouted.

The trainers' shocked was replaced with smiles.

''That's cool!'' proclaimed Bonnie.

''Yeah!'' exclaimed Max.

''How'd do that?'' asked May.

''The watch that I was wearing it's called the Omnitrix which turned me into super powered aliens.'' explained Jetray.

''Alien? No way.'' breathed Dawn.

''Mind blow.'' muttered Serena.

''What about the rest of you?'' Brock asked Gwen, Kevin, Rook, and Julie?''

Gwen used her mana to create a force field, Kevin absorbed the ground, Rook took out his Proto-Tool and Ship shifted into Battle Ship Mode.

''So, where you guys come from?'' inquired Iris.

''Long story short, we're come from another dimension.'' explained Gwen.

''And there no Pokemon we come from.'' remarked Rook.

''Alright, let's not waste anymore time, let's get going.'' said Jetray. As the Aerohibian grabbed Rook and Kevin and flew up in the air.

Gwen create a mana plateform and grabbed Julie, May, Misty, Dawn, Iris, Serena, and Bonnie.

''Charizard! I choose you!'' Ash sends out his first Fire type Pokemon, who give a Flametrower to the face.

''Ash, are you okay?'' questioned Goh.

''I'm okay...'' he muttered.

''Does your Charizard do that a lot?'' wondered Goh.

''Yeah, a lot.'' answered Brock.

Ash, Brock, Goh, Max, Cilan, and Clemont hopped on Charizard's back, they start flying on top of the top.

After the group landed on the top, they all saw that all the Bulabsaur and Ivysaur were basking in the sun.

''The Bulbasaurs' bulbs are taking in sunlight and growing bigger.'' inputted Goh.

The Inysaur's flow opens as it absorbs the sunlight and a Sweet Scent fills once again.

''The scent's really does smells good.'' chimed Bonnie.

''It's sure does.'' agreed Iris.

''Does this mean they really did come here seeking stronger sunlight?'' asked Ash.

''Yeah, sure they are.'' answered Brock.

''This bring back memories.'' smiled Misty.

''I know! We might understand them better if we come Iysaur ourselves!'' suggested Goh.

''That's a great idea!'' cheered Ash.

''Why not.'' shrugged Clemont.

The others nodded in agreement.

Then they try to act as the Pokemon together. Ben decided to contact the Grass Type Pokemon. ''How about I'm act like a plant with a plant.

He activated his Omnitix and slammed the dial down after he selected the alien he was looking for he was engulfed in a flash of green light. When the green died down standing in his place was a humanoid plant-like alien that has an overall green and black colored body, mostly with a flame-patterned head and root-like feet, seemingly holding black rocks. His eyes are oval-shaped with points at each with pupils copying the shape but are smaller. Also his shoulders and head have red petals and his elbows and legs have green frills sticking out. He is taller than an average human. He wears the Omnitrix symbol on his chest.

''Swampfire!'' he shouted in nasally voice.

''Wow, a plant guy.'' grinned Max.

''So cool!'' exclaimed Dawn.

''Thanks.'' said Swampfire with a smile.

''Why he is called Swampfire?'' asked May.

''Because, he can do this.'' replied Swampfire. The Methanosian grow vine whips from his right arm and engulfed fire with his left one.

''Whoa, he can control both fire and plants?'' inquired Serena.

Swampfire nodded. ''I also control the sentinel plant on both Earth and space.''

''Indeed Swampfire's race the Methanonsains are known for controlling both fire and plant life.'' explained Rook.

''I have get a watch like.'' replied Max.

''Me too.'' agreed Ash.

Then the wind started around them.

''Wow, this feels nice..'' commented Dawn.

''I know.'' responded Ash. ''The wind is so pleasant.''

''This spot is famous in Vermilion City for its strong winds.'' explained Goh.

Just then the Bulabasaur and Ivysaur started to glow.

''Is this evolution?''

But then, a net appeared and it captures all the Bulbasaur and Ivysaur.

''What the?!'' screamed Ash.

''Prepare for trouble!''

''And make it double!''

''To protect the world from devastation!''

''To unite all people within our nation!''

''To denounce the evils of truth and love!''

''To extend our reach to the stars above!''

''Jessie!''

''James!''

''Team Rocket blasts off with the speed of light!''

''Surrender now or prepare for a fight!''

''Meowth! That's right!''

''Wobbuffet!''

Ash and his old companions groaned.

''Team Rocket!'' shouted Ash. ''Not you guys again!''

''You guys never charge do you!'' yelled Misty.

''Looks like all those twerps and twerpettes from Kanto, Hoenn, Sinnoh, Unova, and Kalos are back as well.'' pointed out Meowth.

''And the one who stole my title for the Kalos Queen!'' glowed Jessie with anger.

''Whoa, it's the talking Meowth.'' smirked Goh as he take pictures of the Normal Type Pokemon with his phone.

''And there are 6 new ones as well.'' noticed James looking down at Goh and the Alien Force.

''Do they always called you guys twerps all the time?'' questioned Ben who turned back to human earlier.

''Yep.'' answered Iris.

''They've always changed after us all over the world.'' stammered Brock.

''Here in Kanto. Johto.'' began Misty.

''Hoenn.'' added May and Max.

''Sinnoh.'' added Dawn.

''Unova.'' added Cilan and Iris.

''And Kalos.'' finished Clemont, Serena and Bonnie.

''Team Rocket! Give us back Ivysaur and Bulabasaur!'' cried Ash.

''Yeah, you heard the kid let them go!'' screamed Kevin.

''With so many of them gathered in one place, it's like they're saying. Please steal us!'' laughed Jessie.

''And so, of course, we will do just that!'' proclaimed James. ''Farewell, twerp!''

''Charizard! Use Slash!'' commanded Ash.

Charizard roared as he cut through the net. causing all the Ivysaur and Bulabasur to fall of the next.

Ben activated his Omnirix and slammed the dial. When the green died down standing in his place was a 12-feet tall humanoid dinosaur-like alien with brown outer skin, and a tan underbelly and underarms. He wears the Omnitrix symbol on his chest.

''Humunogsaur!'' he shouted.

Humungosaur grabbed most of the falling Grass and Type Pokemon with his arms and placed them on the tower safely. Then he turned back to Ben.

''How dare you take our Bulabsaur and Ivysaur!'' snapped Jessie.

''We're going down! Meowth!'' panicked Meowth.

Their Meowth High Air Ballon landed on the tower.

''You have some nerve, you know that?'' inquired Jessie.

Just the, a Pelipper with Team Rocket's logo appeared and it drops a machine.

''This is the secret weapon?'' questioned Meowth.

''Looks like a vending machine to me.'' answered Jessie.

''Well, then we'll have to put in a coin!'' called out James.

''But do we even have one?'' asked the Normal Type Pokemon.

Jessie and James shove Meowth's headfirst into the colt slot, using his golden charm to activate the machine. With a turn of the crank, Jessie and James receive a pair of Rocket-Branded Poke Balls.

''So these Balls contain awesome Pokemon that Giovanni picked out, huh?''

As they send out, there is a Gyardos and a Tyranitar.

Ash and his friends took out their Pokeballs.

''Squirtle! Blastoise!'' I choose you!'' yelled Ash.

''Steelix!'' yelled Brock.

''Psyduck!'' shouted Misty.

''Blaziken!'' cried May.

''Piplup!'' shouted Dawn.

''Pansage!'' exclaimed Cilan

''Excadrill!'' proclaimed Iris.

''Heliolisl'' yelled Ciemont.

''Delphox!''

''Charmander!''

Their Pokemon.

Ben activated his Omnitrix and slammed the dial. When the usual green light died down standing in his place was a humanoid moth-like alien with a blue robe with a hood, giving him the appearance of a phantom. He has a black and blue body. He has cyan patches that resemble ice chucks on his legs and arms. His eyes are bright green with small dark spots inside. His mouth is a frown showing four bluish-white teeth, which rarely moves, even speaking. He has three pointed fingers and a thumb on each hand, and three on each foot; two in front and one behind. His unfolded his hood, which was revealed to be four wings and a pair of funny antennas. He wears the Omnitrix symbol on his chest.

''Big Chill!'' he shouted in an eerie whisper voice. ''Gwen, Julie you two protected the Pokemon we'll handled Team Rocket.'' he ordered.

Both girls nodded.

Kevin absorbed a part of the tower while Rook ready his Proto-Tool.

''Hey, Ash when you get a Blastoise?'' asked Misty.

''Well, Officer Jenny sent Squirtle and the Squirtle Squad to Professor Oak's lab since they a new one and she decided for me to keep them and one of the Squirtle evolved when I got back from Alola.'' explained Ash.

''So, now have a Charizard and a Blastoise?'' asked Brock.

His long time friend nodded. ''Squirtle, Blastoise! Use Water Gun and Hydro Pump on Tyranitar!'' ordered Ash.

''Psyduck! Use Water Gun too!'' commanded Misty.

''Steelix, Flash Cannon!'' yelled Brock.

''Blaziken! Sky Uppercut!'' shouted May

''Piplup!'' Use Whirlpool!'' ordered Dawn.

''Charmander! Ember!'' cried Iris.

''Pansage! Bullet Seed!'' exclaimed Cilan.

''Delphox! Fire Blast!'' proclaimed Serena.

''Excadrill! Drill Run!'' yelled Iris.

''Heliolisk! Use Thunderbolt!'' shouted Clemont.

''Squirtle, Blastoise, Psyduck, Steelix, Blaziken, Piplup, Charmander, Pansage, Delphox, and Excadrill fired their attacks at Tyranitar, while Heliolisk fired his attack at Gyarados whose dodged the attacks, Gyarados is using Ice Fang on Charizard, who manages to dodge. Tyranitar also uses Fire Fang on Big Chill but the attack phased through him.

''Intangbility.'' said Big Chill then took a deep breath and used his ice breath freezing the Rock and Dark Type Pokemon.

''Charizard, Blastoise! Dragon Claw! Flash Cannon!'' yelled Ash as both of his Pokemon used their attacks to deal some damage to the two. But Charizard is hit by Stone Edge and Blastoise is hit by Dark Pulse.

''Now let's finish them with the attack.'' Team Rocket thinks that they are going to win but, the Inysaur fires Solar Beam at them.

Tyranitar and Gyaradoes decided to defeat them the Inysaur with Hyper beam attacks.

''Not this time.'' replied Big Chill.

Big Chill slapped the Omnitrix symbol as four spikes popped out and a flash of green light spread his body. When the light died down Big Chill's red is recolored red, his wings and antennae have a flame design, and he had crests over his eyes with the same design.

''Ultimate Big Chill!'' he shouted in a deep eerie voice.

Ash, and his companions looked at the Evolved Necrofriggian.

''Ultimate?!'' they exclaimed.

''Alright, time to finished the job off.'' said Big Chill fired his flame-ice breath from his mouth.

''Charizard! Flamethrower! Squirtle! Water Gun! Blastoise! Hydro Pump! Pikachu! Thunderbolt!'' yelled Ash.

''Steelix! Stone Edge!'' shouted Brock.

''Piplup! Hydro Pump!'' yelled Dawn.

''Pansage! Rock Throw!'' cried Cilan.

''Delphox! Fire Blast!'' yelled Serena.

All of the Pokemon fire their attacks and it causes an explosion sending Team Rocket into the air.

''It seems like the twerp has gotten his Pokemon back on his team.'' replied Jessie.

''And those other twerps are back again and one of the new ones can transform himself into Pokemon. So we'd better stick to our original plan'' responded James.

''We'll get that Pikachu, that watch, and other Pokemon of theirs, meow!'' mumbled Meowth.

''We're blasting off again!'' screamed the trio as they are out of their sight.

''It's looks they gone.'' stated Ultimate Big Chill in a flash of green light he transformed back to Ben.

''Hey, Ben with the Ultimate Big Chill thing?'' asked Ash.

''The Omnitrix has a hyper-evolved function which allows me to evolve my alien transformations into their Ultimate forms. And there is another function that powers them up.'' explained Ben.

''That's was cool.'' commented Max.

''Yeah, you guys were awesome teaming up together.'' added Bonnie. She pointed to the Alien Force. ''But you guys are the coolest.''

''Thanks.'' smiled Rook.

''This one seems like to like us.'' smirked Kevin.

''Yeah.'' agreed Gwen.

''I'm starting to like her and the other girls.'' reported Julie.

''Now that's that.'' remarked Goh.

The group notices the Ivysaur evolving into Vensaur. Ash takes out his Rotom Phone and scans them.

''Vensaur, the Seed Pokemon. A Grass and Poison type and the final evolved form of Bulabsaur. It's believed that a nutritious diet and a lot of sunlight make Venusaur's flower bloom in more vibrant colors. The flower's scent can calm and heal the human heart.''

The newly-evolved Vensaur promptly polled into the air, causing the bud across Vermillion City to bloom into flowers. The young Bulabsaur follow suit, all evolving into Ivysaur.

''So the Ivysaur come here to use the wind to spread their pollen.'' realized Goh.

''Yeah.'' nodded Ash. ''Charizard! Use Flamethrower one of the Venusaur.

Charizard roared and did what his trainer told him and damaged a Venusaur with his attack and then Ash threw a Pokeball at the Vensaur and he succeeded in catching him.

''Alright, I'm captured a Vensaur!'' cheered Ash now his three fully-evolved Kanto Starters though his Bulabsaur and Squirtle don't wanted to evolved.

His friends including Ben and the rest of the Alien Force cheered for their friend including Pikachu, Squirtle, Blastoise and Chardizard.


Back in the lab, Professor Cerise was watching the video.

''The mysterious strength hidden in Venusaur's pollen...another grand discovery.'' said Professor Cerise.

''Well, when up against the ultimate team of me, Goh, Ben, Gwen, Kevin, Rook, Julie, Brock, Misty, May, Max, Dawn, Cilan, Iris, Serena, Clemont and Bonnie. It was an easy job.'' replied Ash.

''We're to make a team.'' commented Goh.

''Yeah.'' agreed Ben. ''I have to admitted we've make a great team.'' he smiled.

''Well, said partner.'' nodded Rook.

''Yep.'' smirked Kevin.

''Today is quite fun, we got to see the moment they evolved.'' imputed Brock.

''Yeah.'' nodded May.

''And it was pretty.'' added Dawn.

''Plants are always pretty.'' compliance Gwen.

''They sure are.'' agreed Julie.

''And I see you also have capture a Venusaur, that is also great as well.'' responded Professor Cerise.

''I'm back!'' Chloe comes back to the lab.

''Welcome home, Chloe. What took you so long?'' asked Professor Cerise.

''All the flowers at the school bloomed at once. I was in charge of the cleanup...it was so much work.'' answered Chloe.

Ben, Ash and their friends looked at each other and then they burst out laughing.

''What's with you? How creepy.'' stated Chloe.

''In any case, my exceptional research fellows have solved the mystery of the Ivysaur march. Thank you.'' reported Professor Cerise.

''You very welcomed Professor.'' spoke Rook.

''But still have a lot of search to do.'' remarked Cilan.

''Learned about Pokemon around the world.'' added Clemont.

''And do our very bad.'' finished Iris.

''I'm gonna to captured a lot of Water Type Pokemon.'' smiled Misty.

''And we've traveled with our friend Ash again.'' added Serena she was happy to travel with Ash so did the others.
