He knew this alien.
"Walkatrout."
The most useless alien in the entire Omnitrix.
Jack closed his eyes and took a slow breath. Then he stared at himself in the mirror for a long time, and the little blue alien stared back. It had big round eyes, tiny fin arms, a dorsal fin running down its back, and two thin legs that looked like they belonged on a completely different creature.
Jack slowly raised one fin, and the alien in the mirror copied him.
"...You have got to be kidding me."
He had watched Ben 10 in his past life, so he knew some of the iconic aliens, and among all the ones he knew, this one was the worst. A fish. Not a cool alien, not a powerful alien. A very small fish.
Information appeared in his head, as if the Omnitrix was sending it directly to his brain.
[ Species: Ickthyperambuloid ]
[ Home Planet: Aqua Neth ]
[ Abilities: Slippery body, enhanced durability, underwater breathing, acrobatics ]
"Acrobatics."
Jack looked at his tiny legs.
"Sure. That'll definitely save me from Thanos."
He tried to walk. Step. Slide.
"Whoa!"
His legs shot out and he nearly crashed into the wall. He grabbed the table just in time. Right. Slippery body. That ability didn't only work on other people, it worked on himself too.
He tried again, more carefully. Step. Slide. Step. Slide. Within seconds, he was gliding across the floor like a hockey puck, until he bumped into the couch and stopped.
"I can't even walk."
He sat on the floor and looked at the ceiling. A timer appeared in the corner of his vision.
[ Transformation Time Remaining: 07:31 ]
Ten minutes total, then one minute to recharge. That matched the cartoon.
"Well... I'm already transformed. Might as well test everything."
He pushed off the ground, and his body flipped in a full mid-air spin before landing cleanly.
"Oh."
He tried again and jumped higher. His body twisted twice before landing perfectly on both feet.
"Okay. That's actually really good."
The acrobatics weren't average, they were automatic. His body just knew how to move, like the alien form had built-in instincts that came with it. He started jumping around the room, flipping off the couch and rolling across the floor without slipping once. In the air, he could spin and twist like gravity was optional. If anyone looked through the window right now, they would see a tiny blue alien doing gymnastics in someone's apartment.
Jack landed and caught his breath. Then he walked straight into the wall.
Thud. Nothing. No pain.
He hit it again, harder. Still nothing.
"The durability is real."
Even a weak alien was still an alien, and the body was naturally tougher than a human's. He couldn't fight anyone with this form, but he also wouldn't break easily.
The timer blinked.
[ Transformation Ending: 00:08 ]
Green light wrapped around his body, and in seconds he was human again. He looked at his hands. Normal. Ten fingers. No fins.
[ Omnitrix Recharging — 60 seconds ]
Jack sat on the couch and let out a long breath.
From the system, he had now learned that he was reincarnated, and that it had been 18 years since he came to the Marvel world, so this world didn't feel very alien to him. Now, with this memory and thinking about his experiences...
"My life just became a web novel plot." Jack laughed, but he wasn't complaining.
There was one thing he didn't like, though, and that was school. The school he was attending was very famous in his past life, and many famous people had studied there. It was Midtown High School, the same school Spider-Man attended. He had been attending it for the whole of high school, and he seemed to talk with others, but there was nobody he could call a best friend. Even "friend" was a distant word for him.
Thinking about school, one girl's face appeared in Jack's memory. There was a girl in his class who always carried a guitar case. Blonde, blue eyes, confident the way some people just are, not loud about it, just solid. He had seen her a thousand times but had only spoken to her a few times.
Gwen Stacy.
But this Gwen was not the one he had seen in his past life's movies. The Gwen he knew was not a shy nerd or a quiet genius. This version of Gwen played guitar in a rock band. She had the kind of presence that made a room feel different when she walked in.
And then there was Peter Parker, who looked very similar to the Amazing Spider-Man version.
"I can't wait to see how these people I only knew from fiction will be in reality!" Jack felt excited about it.
