Author's Note: Honestly I'm surprised why not a lot of people had thought of this before, especially since these two series are so alike: Alien goes to earth, meant to cause destruction, but turn good in the end and become one of the galaxies or universe's greatest hero. Stitch belongs to Disney and the Dragon Ball franchise belongs to Akira Toriyama.

Prologue

Galactic Federation Courtroom

A darkened room with many figures covered in shadows that loomed over what could be described as a 5 mile drop, with a walkway and hovering platform above it. A light then turned on as a turquoise skinned alien in a black robe with gold outlines walked up to the podium.

"Read the charges," the before mentioned alien said in a voice determining that she is female. Our attention is then turned to a what could be called a giant land shark holding a list that the alien on the hovering platform was charged with. Speaking of the alien, he had dark purple outer skin and purplish pink inner skin color. He wore a white lab coat with brown pants and black boots (he was also quite chubby). He had foureyes instead of the usual two like most creatures in the universe.

"Dr. Jumba Jookiba, you are hereby charged with creating illegal, genetic experimentation." The giant land shark whose name was Gantu, read off the paper.

"How do you plead?" The female alien whom everyone just called the Grand Counsel Woman asked the now named doctor.

"Not guilty," Jumba countered. "My experiments are only theoretical, and in totally legal boundaries." As he was speaking, another hovering platform that was covered in a metal shell began floating next to Jumba.

"You mean you actually created something?" The Grand Counsel Woman asked.

"Created something?" Jumba said sounding offended. "Hah! Now that would be irresponsible. No I would never, ever…" Just as Jumba was about to finish, the other hovering platforms shell popped off, revealing a blue, furry, four armed creature in a red jumpsuit, trapped inside a glass container. "... make more than one," Jumba finishes.

Looking more at the creature, it had two antennas a top it's head, and three blue spikes protruding from it's back. It had deep black eyes, and two rabbit like ears were each had a triangle cut out beginning from the ear's edge.

"What is that thing?" Gantu asked.

"You like?" Jumba asked Gantu back. "I call him, Experiment 626. He is bulletproof, fireproof, and is capable of lifting things over 3,000 times his own weight. He can see in the dark, and is programmed to destroy absolutely everything in its path! Hahahahah!"

"So it really is a monster," the Counsel Woman stated.

"Hey, just a little one."

"We should destroy it at once!" Gantu suggested.

"No Gantu, perhaps we can reason with it. Experiment 626…" The Experiment in question was busy trying to find a way out of the containment, but stopped after hearing the Counsel Woman speak to him. "...show us all that what Jumba says is wrong. Prove to us that you are not a monster and are good."

626 stood up, cleared his throat… everyone now leaning in listening in anticipation. "Meega nala quiesta!" He shouted, offending or disgusting everyone in the room.

"So naughty!" 626 just laughed in amusement at what she said.

1 hour later, The Federation Mothership

The ship at the moment was flying through a cosmic storm, nothing that a mothership couldn't handle, but could prove dangerous for a small spaceship, also 626 was escaping.

Not too long ago, 626 broke out of his containment cell using his superior intellect and has now run rampant, shutting down the power and looking for a way off the spacecraft. He was successful in finding a mini police space cruiser that was colored red. Gladly taking it, he flew out into the storm, preparing a hyperdrive.

Back on the control bridge, Gantu was just informed of the space cruiser making its escape. "The fool! He's flying in a cosmic storm? Doesn't he know what kind of damage he'll deal to the cruiser or himself?!"

As he was saying this, just before the hyperdrive activated a bolt of cosmic energy zapped the cruiser, overloading its circuits and 626 getting one heck of a shock. The hyperdrive then activated, blasting him to who knows where (though I'm sure you already know).

"Gantu! What happened?" The Grand Counsel Woman asked over a radio.

"I'm afraid the trog got away," Gantu replied.

Main Control Room

"He jumped into hyperspace, track him!" The Counsel Woman commanded.

"I'm afraid we can't ma'am, the cosmic storm is jamming our tracking signal."

"Drat! First we have an intergalactic warlord on our hands and now this! If Frieza gets his hands on 626, the galaxy, no the entire universe just might be doomed as we know it!"

Sometime later on Earth

626's ship crash landed in some secluded forest. When he got out, his jumpsuit was torn to shreds, his walk cycle was wobbly and was on the brink of passing out. That cosmic bolt didn't just overload the cruiser, it overloaded 626 as well, causing him to completely forget his programming. Unknowing what to do, 626 wandered until passing out from exhaustion. But before he completely blacked out, he heard what sounded like a kid yell, "Grandpa! I found something over here!"
