One month earlier

New Town, once a peaceful place, never threatened by monsters or giant robots. Then one day…

Ze Professor and Dry Bowser were testing different chemicals.

"Good morning, Professor and Dry Bowser!" Tails greeted as he pushed a cart with tea, scones, and Barklei sitting on the cart, being the curios robot puppy she is. "I made you some tea!"

"Thanks, Tails!" Dry Bowser thanked.

"Zank you!" Ze Professor thanked.

"So, how's the analysis going on Chemical X? Is it stabilizing?" Tails asked.

"Hmm… No, Tails, not yet." Dry Bowser said.

"Nozing ve tried, so far, is verking!" Ze Professor admitted.

"But, I'm pretty confident. Once we find the stabilizer, we'll be able to balance out any chemical or meteorogical annalobee, at least, that's what I hope. Hey are those scones? They're my favorite! Maybe this'll help me think…" Dry Bowser said as he grabbed a scone. Barklei started barking, as though she wants one.

"No, Barklei, those aren't for you. You're just a robot, remember? What would you want with a scone anyway?" Tails asked as Barklei started whimpering. "Alright, okay! Here you go" Tails placed Barklei on the cart as she had one scone in her mouth and one in her clawless paw. Tails, Dry Bowser, and Ze Professor started laughing as Barklei starts dancing around.

"Okay, Barklei, that's enough!" Tails said as he attemped to grab Barklei, only for her to slip on her back. She lost her gril one a scone as it fell into a container filled with Chemical X. Tails, Dry Bowser, and Ze Professor gasped in horror as the chemical started changing colors. As it turned into a whitish color, the Chemical X shows off a bright light.

"Can it be?" Ze Proessor mumbled as he, Tails, and Dry Bowser were staring at the improved chemical. He takes out a turkey baster to take a drop of it and put it into a machine.

Commencing anaylisis…Stablyzation complete! Chemical change potential for altering molecule destructions.

Ze Professor and Dry Bowser sweatdropped as Tails seemed to be happy about this.

"We did it, guys!" Tails cheered.

"Well, thanks to you and Barklei, of course." Dry Bowser said uneasly as Tails started swinging Barklei around.

"It's no longer Chemical X, no, it's somzing else. Yes, Chemical Z!" Ze Professor exclaimed.

Chemical confirmed!

"Well, what do you think, Tails?" Dry Bowser asked.

"Chemical Z? Sounds good to me!" Tails said.

Confirmed! Chemical Z now being regristered into the scientific federation!

"Excellent!" Tails cheered.

But, something wasn't right… Outside of the window, falling snow can be seen.

"Snow? In the middle of summer?" Tails asked.

"Zis doesn't make sense!" Ze Professor exclaimed.

"And it seems to be going on all over town!" Dry Bowser exclaimed. "Mr. Mayor!"

A communiacater screen showed Mr. Mayor as he turned around.

"Oh! Professor, Dry Bowser, and Tails, I'm so glad I caught you three! We need your help! It's the weather! Things have gone completely crazy!" Mr. Mayor said.

"Yes, we have seen it too!" Ze Professor exclaimed.

"You have? Then you must know about the icebergs that are now forming all over the city." Mr. Mayor said as the communicater screen showed all of the icebergs in New Town. "Soon New Town will look like the North Pole!" The communicater screen showed hundreds of penguins waddling around. "I think it's the penguins, yes the penguins are trying to taking over New Town." Mr. Mayor said.

"Sir, I don't think it's the penguins!" Mrs. Bellum corrected.

"In that case, it must be an evil snowman!" Mr. Mayor concluded.

"It's not only New Town, sir, it's happening all over the world is acting strangely. There are blizzards in Egypt, Romosca is a desert, there's a drought in Venice, and it's been raining nonstop in Austrailia!" Mrs. Bellum said as she proved it.

"It cannot be!" Ze Professor denied.

"Guys, I have an idea! What if we use Chemical Z to repair all of the damage?" Tails asked.

"Not right now, Tails, zere is still a lot of work to be done! Right now, zere is no telling what could happen if we try-" Ze Professor said before he got interupted. "Vere did Tails go?!"

"Don't look now but…" Dry Bowser said as he saw Tails operating a giant ray gun, making Ze Professor look.

"Ze Chemical Z! It's gone!" Ze Professor exclaimed. "Tails, vait! It is too soon!" as he and Dry Bowser ran to the ray gun.

"Target cited!" Tails said as he used a scope to aim his shot.

"Tails, vait!" Ze Professor said.

"Don't do it!" Dry Bowser said. Too late, because Tails has already shot the laser at an iceberg, making everything back to normal. As the iceberg broke into white and black rays, scattering all over New City.

"Z-rays? What does this mean?" Tails asked as he watched the rays scatter.

Conker walked out of a mall with a bag in his hand. "Woah, what do those rays mean?" He asked as he heard his stomach growl "I guess I better get going. I'm getting kinda hungry!" as he walked to a nearby bench. "Time for a snack!" Conker said as he searched inside his bag for something to eat. He took out a chocolate bar as he saw a white Z-ray falling towards a kid playing with his sling shot. "Hey! Look out!" Conker shouted as he ran to the kid and covered him, getting hit by the strange white light.

He began his first transformation scene. "Conker!" Conker shouted as he transformed. After he had on his super hero outfit, he ended his transformation scene with a pose.

"What just happened?" Conker asked as he glanced at his outfit "Somebody better tell me what's going on here."

Toadette is seen walking to the mall as she had every boy she met on they way swooning over her.

"Hiya, Toadette!"

"Hey, I really like your hair!"

"Need someone to walk you home?"

"Hi there! Thank you! No, I'm fine!" Toadette responded.

"Maybe after school, we could get a soda?"

"Sorry, guys, I'm busy!" Toadette said as she walked off, leaving all of the boy drooling. When Toadette got to the mall and into the clothing department, she decided to increase her wardrobe. "Hm, this color's perfect for me!" Toadette giggled as she skipped and hummed merrily. She saw a kid blowing bubbles and ran over. "I remember when I was little, I used to make bubbles just like these!" Toadette said before she turned her attention to an incoming white Z-ray. She covered the kid.

Toadette started her first transformation scene. "Toadette!" Toadette shouted as she transformed. After she had on her new outfit, she ended her transformation scene with a pose.

"I don't remember buying this outfit…" Toadette said as she glanced down at her new attire.

There was a large group of people watching Daisy skating, using her roller blades.

"Coming through!" Daisy said as she skated down the sidewalk. She saw a kid sitting on a bench and the Z-ray that was heading straight for him. Daisy had to act fast, so she stopped in her tracks and covered the kid.

Daisy started her first transformation scene. "Daisy!" Daisy shouted as she transformed. After she had on her hero outfit, she ended her transformation scene with a pose.

"Oh no! No, no, no! Please don't tell me I'm wearing a skirt!" Daisy exclaimed as she clearly hated her outfit.

Diddy is at a playground, trying to improve his tumbling skills for an upcoming gymnastic meet.

"Okay, here I go…" Diddy prepared as he readied himself. He went off in a running start, but stopped as he saw a white Z-ray heading for a kid playing with a jump rope. Diddy ran to the kid to cover him.

Diddy started his first transformation scene. "Diddy!" Diddy shouted as he transformed. After he had on his outfit, he ended his transformation scene with a pose.

"When did I get this suit?" Diddy asked as he stood there, confused.

Banjo is sitting on a bench, tuning his banjo. Then... Pluck! One of the strings broke,

"D'oh! I've really gotta buy new strings! Honestly, I just can't get the quality strings!" Banjo exclaimed. Then, he saw a white Z-ray heading for a kid playing a flute. He quickly ran to the kid and covered him.

Banjo started his first transformation scene. "Banjo!" Banjo shouted as he transformed. After he had put on his outfit, he ended his transformation scene with a pose.

"What the…? How did this happen?" Banjo asked as he glanced at his attire.

A white Z-ray is falling to the lab!

"The Z-rays! They're heading this way!" Dry Bowser exclaimed.

"Tails! Be careful!" Ze Professor shouted.

Barklei started growling as she stared at.

"Barklei! Look out!" Tails shouted. But, Barklei didn't listen as she jumped at it. She started having letters, words, and numbers going through her head.

"Woah! That was intense…" Barklei said.

"Yeah, Barklei, it was pretty- Wait! Did you just talk?!" Tails asked in disbelief.

"Hmm… Ze black Z-rays… I vonder vere zey are going…?" Ze Professor wondered as a black Z-ray headed for the New Town Zoo. It hit a lone monkey.

"Ah! Aah! Oh! Mojo… Jojo… Mojo! JOJO!" The monkey said, soon making his voice deeper. The monkey now had black fur, green skin parts, a dome on top of his head, and a black cloak. "Smelly humans, say hello to MOJO JOJO!"

Back with Conker, he practiced on using his slingshot.

"Wow! You're really good!" The kid applauded.

"I never used to be very good at a slingshot. Something very weird is going on here…" Conker said as he tried to think. Then, he heard screaming townsfolk.

"Look out! Run!" a man said.

"Hurry, someone's released all of the animals!" another man said as he grabbed his kid.

"What animals?" Conker asked as a tiger came up to him. The tiger roared, causing Conker to scream.

Back at the zoo,

"Yes! You are free, my brothers!" Mojo Jojo preached as he released the animals "No more cages for you, Mr. Rhinosaurus! You pandas, camels, all of you! Free! I wonder what I should do next… Maybe go this way!" Mojo Jojo ran into the wall, breaking it.

Meanwhile, Conker was face to face with the tiger.

"Hey! That's my homework!" Conker shouted as he tried to pry it out of a goat's jaw "At least, this'll be a good excuse this time…" little did he know that a lizard was at his right foot. He gasped in horror as he saw it hiss.

They're gonna eat me… Conker thought I know they're gonna eat me! What am I gonna do? Get me outta here! Conker accidentally used his new flying powers as he landed himself onto a tree branch. "Well, that was strange… I just sort of flew away, didn't I?" Conker asked as he looked down and saw Mojo Jojo lurking around. "What? Who's that?" Conker asked again.

"Oh! Hello, lion!" Mojo Jojo greeted as he looked at the lion that looked like it was in pain "What are you eating?" he pried the lion's jaw open to see a crème cookie in its mouth. Mojo Jojo licked the cookie until...

"HEY!" Conker shouted "THAT'S MY COOKIE YOU STOLE!" he pulled out a cookie "It's a vanilla crème cookie, which is my favorite! See? First, you just nibble and lick the creamy filling…" Conker demonstrated as he put the whole cookie in his mouth "After that, then the whole thing. If you want to do it right, you have to do it properly with two hands." He explained to Mojo as Mojo started doing it right "See? You're a natural!"

Conker and Mojo Jojo have regained their focus as they took a glance at each other. They screamed in surprise as they realized who each of them were as they both got into a fight stance.

Something's not right here… Conker thought as he saw a black aura surrounding Mojo Jojo First of all, this guy's wearing a big, black cloak. Everybody knows that big, black cloaks are evil! Then, there's that dark aura surrounding his body. That can't be good! Hmm, I think he may be a bad guy!

Hmm, something is not right here… Mojo thought as he saw a white aura surrounding Conker First, I am a big, green creep. Second, I can talk? Third, I am floating in the air and I also want to take over the world. Hmm, I think I am a bad guy!

"So, that means…" Conker and Mojo said at the same time. Then, they started their battle. Conker tried to use his slingshot, but he missed as Mojo Jojo flew over and tried to grab him. Conker got out of the way and fired his slingshot many time while Mojo blocked himself with his hands, but Conker outsmarted him and began firing at Mojo Jojo.

Back at the lab, Mojo Jojo showed up on a computer screen as well as Conker.

"Guys, do you think this may be happening because of the exposure to Chemical Z?" Tails asked.

"Hard to say, but yes!" Dry Bowser answered.

"Most likely." Ze Professor agreed.

Back at the duel, Mojo and Conker were on top of a truck as they continued their battle. Mojo flew away, leaving the almost-falling truck to Conker. Conker used his superpowers to pick up the truck and set it down. He cornered Mojo Jojo at a wall and started firing his slingshot and missed, again, but Conker managed to hit Mojo hard enough to break the wall.

In town hall, Mr. Mayor and Mrs. Bellum watched the fight on a computer monitor.

"It's nice to have someone to defend the city, but if he keeps this up, there will be no city left to defend!" Mr. Mayor complained.

Back with the duel,

"Missed me! Missed me again!" Mojo said as he dodged the flying rocks coming from Conker's slingshot. Conker tried to dodge Mojo Jojo, only to fall into a crate of oranges at a fruit store. Mojo smirked as he cornered the fighting squirrel, but slipped on the rolling oranges that were coming. Conker got up and did his final strike.

"Slingshot supreme!" Conker shouted as he did his final blow on Mojo Jojo, sending him to crash onto Mr. Mayor's car.

"OW! I WON'T FORGET THIS!" Mojo swore as he flew his arms about. He went high into the sky.

"See ya!" Conker said as he blew a raspberry. "Alright, you guys, this way, stay in line!" Conker said as he instructed the escaped zoo animals back to their home, the zoo of course. Then, a huge crowd of people gaped at Conker. "Please, people! No need to thank me! You can have my autograph later!" Conker flattered as the zoo animals went back into their cages. Then, Mr. Mayor pulled up.

"Uh, excuse me, mister. In future, take it easy on the buildings, cars, and uh…" Mr. Mayor said as Conker turned his attention to the damages, police, firemen, and the complaining people. "Now, as mayor, allow me to thank you!"

"Uh, oh! Got to go! Later!" Conker panicked as he flew off.

"Hey, mister, where are you going?" Mr. Mayor asked. Conker didn't answer as he flew away.

Toadette is carrying a shopping bag and her bubble wand as she bounced , with the help of her flying powers.

"I can't believe that weird light thingy gave me these superpowers, this bubble wand and this cool, new dress!" Toadette exclaimed gleefully.

Diddy is trying out his tumbling powers.

"Wow! I knew I was good at gymnastics, but I didn't know I was this good! All thanks to the weird comet!" Diddy said as he tumbled about.

Banjo was trying out his boomerang.

"Hmm, It's kind of weird. I never thought I'd be good at using a boomerang. I guess it was because of that strange light source." Banjo said as he threw his boomerang.

Daisy was sulking around as she carried her hammer.

"I mind it so much if I didn't have to wear this stupid dress… WHAT'RE YOU LOOKING AT?!" Daisy asked in a threating tone.

Ze Professor, Dry Bowser, Tails, and Barklei all jumped in surprise.

"Five normal high school students, each one transformed by Chemical Z." Ze Professor wondered as he looked at the video clips of Conker, Toadette, Diddy, Daisy, and Banjo. "Ve need to find out more about zem, and quickly!"

"Sounds good, Professor, We'll get right on it!" Dry Bowser said.

"But you have to admit, their powers are pretty cool!" Tails added.

"Okay! Let's bring zem in and run some tests!" Ze Professor exclaimed as he hover out of the room.

"I'm in!" Dry Bowser said as he ran out of the room.

"Me too!" Tails said as he ran out of the room.

"Wait for me!" Barklei said as she ran out of the room.
