Prologue

In a jungle on the rural island in Hawaii, a land shark living in a dented ship with a sandwich-hungry genetic expirement named Gantu and 625 were on-screen being telecast by an anthropomorphic hamster who had an accent of some kind confronting Gantu with his past, limitless failures onto capturing other expirements - and Stitch.

Gantu apologised to the baneful hamster as he signed off.

"That little trog and the little girl always gets in my way!" Gantu complained.

"You said that over a million times, well a million and three to be specific," said 625 eating a baloney sandwich.

Gantu grunted.

"There has to be a way to get those little trogs, once and for all!" Gantu roared.

"Like how, when we plan, they foil. What's done is done," said 625.

"I beg to differ," said a gruff, guttural voice.

Gantu jumped and rose an eyebrow. He immediately armed himself with a ray gun.

"Who's there?" Gantu demanded, scanning the ship.

"Not who, but what?" said the voice - until suddenly Gantu was blasted by electricity. He was sent to a wall. 625 spat out portions of his sandwich as he saw Gantu crashed to a wall.

Gantu cried in pain as he immediately got up shooting the walls of his ship.

"Who are you? Show yourself coward!" Gantu demanded.

"Why not you put the gun down and let me finish you off, nice and easily," said the voice from nowhere.

Gantu surprisingly felt himself shivering in fear. 625 went to his side, armed as well.

"I don't know who you are, or what you are, but if you are working for that little punk..."

"Who says about me working for that little girl and her pet?" asked the voice.

Gantu was suddenly punched in the face, then the stomach, and then finally thrown to the wall.

"Gantu!" 625 called, until he was blasted off the floor, and then was kicked to the wall. 625 was unconscious.

"625!" Gantu called.

THUD!

Gantu looked up and aimed his gun at the stranger before. The stranger grabbed the gun and crushed the chamber with little effort. He chuckled evilly as Gantu shook.

"Who says that sharks are tougher on land than in the sea? How a disgrace," said the stranger.

The stranger was a Osmosian. He had a pale, head with tendrils sticking out, had a turtle shell-like torso, yellow, robotic arms, and red robotic legs. He was the most dangerous warlord in the universe, Aggregor.

Coming out from a black portal behind him was the teenaged boy who wore a gray mask and a black outfit, Dark Star.

"You have something that I want, and I have something that you want," said Aggregor.

"Who are you?" asked Gantu weakly.

"Let's say we're just a normal team-up gang who wants nothing but Intergalactic Domination," said Dark Star.

"Intergalactic Domination? Are you insane? The Intergalactic Council will never..."

Dark Star, now growing weary of 625, blasted him with his dark energy weakening him, only difference is that with this, 625's energy was a lot powerful than he imagined. He laughed as he sucked 625's life force away, absorbing it into him.

"I don't know what this thing made of, but I like it," said Dark Star.

Aggregor glared at Dark Star, ordering him to stop.

Dark Star groaned.

"You are just like Ben, and the lovely Gwen you know that?" Dark Star said.

"Shut up," Aggregor shot back as 625 grew some of his strength back. Gantu was horrified at the result.

"Net time, I won't save your friend, nor will I save you. Dark Star has an impending appetite for both of your life forces, I kid you not to fail me," said Aggregor.

"But we are already working for somebody, we work for Hamsterveil," said Gantu.

"Yeah, the Hamster," 625 replied rapidly.

"Too bad, and I thought I was going to let you live," said Aggregor disappointingly looking at Dark Star giving him permission to suck both of their life forces.

Gantu and 625 all screamed in pain as they grew weaker and weaker.

Aggregor let out a smile as Dark Star laughed.

"Okay, okay! You win! Stop, I'm begging you!" Gantu pleaded.

Aggregor signaled Dark Star to stop. Gantu and 625 panted as they spat blood on the floor, barking a hard cough.

"What is it that you want from us?" Gantu asked.

"Destroy the girl and her pet for starters, then go get the last piece of the Forge of Creation on the island's volcano and meet us back here," said Aggregor.

"And don't be late," said Dark Star chuckling.

"As you wish," Gantu and 625 said bowing down to the evil duo.
