In Retroville, Jimmy Neutron and his friends, Carl Wheezer and Sheen Estevez, were gathered in the library. "I can't believe Ms. Fowl has us doing this stupid book report!"said Sheen.

"Ah, c'mon, Sheen, it won't be so bad."said Carl.

"So bad?! This report will make me lose my chance of being the first to watch the Ultra Lord season finale tonight! C'mon, Jimmy, back me up here!"

Jimmy wasn't paying attention because of the book he was reading, "Yeah, yeah, that's great Sheen."he said.

"What're you reading, Jimmy?"asked Carl.

"This book on Multiversal Connections."said Jimmy, "You see guys, after our last interface with Timmy Turner, I was interested with the wonders that lie in the deepest parts of the universe."

"So?"asked Sheen.

"So for my book report, I'm gonna use the Neutronic Gravitational Wormhole Generator 9000 to travel into these other realities and gather data on the behavior and differences that differ from our own. And the best part: there's no way Cindy Vortex could possibly top that."

"Aw, but her reports are always cooler than yours!"said Sheen.

"No offense, Jim."said Carl.

"None taken."sighed Jimmy. His watch then beeped. He pressed the button and a screen flipped open revealing a picture of the Yolkian mothership. "Shoot, it's the Yolkians! They've come back to Earth."

"Yay! Maybe they'll give us free stuff again!"said Sheen.

"I doubt it."said Jimmy. He pressed another button on his watch to contact his robotic dog, Goddard. "Jimmy to Goddard. Meet me at the Library stat! And bring me the rocket."He turned of his watch and turned to Carl and Sheen, "I'll go investigate while you two stay down here in case the Yolkians try to invade Retroville. Gotta Blast!" Jimmy then proceeded to run out the door as quickly as possible.

Sheen and Carl just stood there. Sheen piped the question, "You wanna hit the Candy Bar?"

"As long as you're buying."replied Carl. The two ran out of the library toward the Candy Bar.

Meanwhile, on the mothership, Tak was fixing up the Yolkian technology by merging it with Irken technology. Tak and King Goobot watched as both alien races were at work. "You see, your highness,"said Tak, "By merging the technological advances of both of our home planets, it'll prove much more devastating for our plan."

"Fascinating."said Goobot, "Say, why don't we see how the other villains are holding up?"

"Great idea."said Tak as the two walked off into the control room where everyone was in conversation.

Vlad and Plankton had become indulged in one another's back stories. "I mean, can you believe that?"said Plankton, "Someone just taking what's rightfully yours."

"Hmm...I know how that feels."Vlad replied thinking about the crush he had and still has on Maddie Fenton. "But I still don't understand how a mere one ounce sea sponge is able to outwit you?"

"Yes. I've learned my lesson not to underestimate him. One time he stopped me by turning into a so-called 'Rock Wizard'. Hey what about that 'Danny Phantom' fellow you keep bringing up."

Vlad groaned. "Oh, don't even get me started! For one thing he's the son of that nimrod, Jack Fenton and he always has two troubled teens at his side. One time, when I established my home base in Colorado to make a perfect clone of Daniel, his friends were still able to track me down!"

Another odd conversation popped up between Azula and Verminous Snaptrap. Azula was barking orders to her troops through a walkie talkie just as Snaptrap was ordering Larry, Ollie, and Francisco around.

"Right on it, boss!"said Ollie as he and the other members of doom dashed off.

"Eeshh!"said Snaptrap turning to Azula, "Minions, huh?"

"I agree they can be quite a pain."said Azula, "They can't even read blueprints right!"

"Hmm...hey word of advice..."he whispers into Azula's ear.

"And that really works?"she asked to which Snaptrap nodded. Azula turned the Talkie back on, "Tell the troops they'd better get it right or else I'll dunk them all in a Shark Tank!"

Snaptrap gave Azula two thumbs up.

Meanwhile, Anti-Cosmo and Vexus were discussing some recent invasions they had planned. "I once had an idea to use a villain from this universe to free me! He was a complete nimrod for trusting me! Isn't that right, Clarice?"

"Erm, it's Vexus." said Vexus reluctantly.

"I had an idea for bringing XJ9 to the Cluster by bringing the Cluster to her! It actually went better than I expected. However your plan was good too, Cosmo."

"ANTI-Cosmo."said Anti-Cosmo, "I don't ever want to be associated with that horrid excuse of a fairy..."

Ed Bighead, Simon the Monster Hunter, and Rancid Rabbit were in the weapons department drawing blueprints while making small talk.

"So what drove you two to villainy?"asked Rancid.

"Monsters."said Simon.

"Annoying neighbors."said Ed.

"What about you?"

Rancid replied, "I'm just in it for the money as all...and making a fool of that 'CatDog'."

"Attention everyone!"yelled Tak, "Are the plans ready for world er-excuse me, UNIVERSAL domination? Hm?"

Azula stood up. "My troops are establishing our headquarters in Royal Woods, Michigan as we speak. No heroes and no villains as far as we know."

Anti-Cosmo piped up. "And our plan for the attack on Fairy World is nearly underway!"

"Our B-team of villains is also underway!"said Plankton, "So far, we've got a chalk-drawing named Skrawl, some guy called Glowface, and a little green girl named Vendetta to join."

The three 90's villains stood up.

"And we've got the designs for our new weapons!"said Ed.

"Sure to annihilate those 'heroes'!"added Simon.

"Excellent!"said King Goobot. "Now all that's missing is-"Soon, alarms were blaring and lights were flashing, "-Jimmy Neutron."

Jimmy landed the Strato XL on the launch deck of the mothership. He and Goddard then jumped out. "Perfect landing."Jimmy bragged,

"Bark, bark!"said Goddard in reply.

"Now let's hurry! I suggest we send a nanobot into the main computer hall to sniff out King Goobot's nefarious plot and-"

"Someone help us!"said a female voice.

"Huh?"said Jimmy pointing into another room, "It's coming from in there!" He opened the door that slid open for him when he hacked the panel. "Hello? Is anybody here?"

The female voice came from none other than Helga Pataki trapped in a cell with Arnold, Gerald, and Ginger Foutley. "Yeah that was me."said Helga angrily, "Now let us out!"

Jimmy narrowed his eyes at Helga and turned to Arnold for answers. "What happened to you guys?"

"We're not sure."replied Arnold, "We were just coming back from a school field trip..."

Gerald finished, "Then, the next minute were on this weird ship with this red haired chick over here!"

"The same thing happened to me but I was at home writing in my diary!"said Ginger.

"Criminy!"yelled Helga to Jimmy, "Look, Egg-Head, you gonna help us out or not?"

Jimmy commanded to Goddard, "Goddard, search for a weakness in the cell's security barrier. And-"unbeknownst to Jimmy, Goobot and Tak were behind him and knocked him out with a sleeping gas on Tak's wrist."and...and..."he fainted.

When Jimmy came too, he was in the cell with the other four.

"You okay, man?"asked Gerald looking down on him.

Jimmy got up from the floor, "I'm fine."he looked at both his side to see Goddard was gone, "Huh? Leapin' Leptons! Where's my dog!?"

"Don't worry."said Tak on the other side holding the cybernetic canine, "We'll take good care of him!"

"I do wish we had more time to talk Neutron."said King Goobot, "But I simply must be off to continue my evil deads, Ta-ta!" He and Tak left the room and shut the door.

"Way to go, genius."said Helga.

Jimmy grunted. "I don't know who you are,"he said, "But you're already starting to sound like a Cindy."

"Tell me about."said Ginger

Arnold said, "You and me both."

"Hey! I'm right here, y'know."said Helga
