Walking through the park one day...
"Ooh! What pretty eyes he has!" A woman commented as she took a look inside the stroller.
"Thank you." Inko Midoriya said with a smile. "I'm not quite sure what side of the family he got them from but they are quite distinctive."
"Oh? Better keep an eye on this one then. He just might surprise us all." The woman said. "Such a charmer he is."
Baby Izuku giggled and blinked his red eyes with black sclera at the woman who at least looked older than his mom.
The park was fun!
A few years later...
"Owie." Izuku muttered as he zapped himself on the doorknob to his room again. Even after complaining to his mom about it and getting a humidifier in there he was still shocking himself sometimes.
He paused as he realized what that might mean!
"Mom! I think its my Quirk!" He said as he ran down the hall towards his mom.
"That's great sweetie. We'll get you checked out soon okay?" Inko told her son after he had finished babbling about electricity.
In the park...
"Static electricity?" Katsuki Bakugo said with a snort. "That's nothing. I can make explosions!" He said as he let off a small blast in his hand. "I'm gonna be the number one!"
"No! I will." Izuku said as he his eyes glowed briefly. It wasn't much but it was enough to intimidate the already cocky four year old Bakugo. "The doc said my Quirk might evolve!"
"Whatever, Deku." Bakugo said as he walked off with his other friends behind him.
Izuku fought back some tears. He'd find other friends. Ones that thought his Quirk was cool.
A different Preschool...
"Woah!" Kyoka Jiro said as she watched Izuku shuffle the deck of cards. "How did you get so good at that?"
"Card videos are almost as cool as All Might!" Izuku said with a grin. "So... Go Fish or Old Maid?"
"Go Fish!" Kyoka said as she pointed an Ear Jack at him. "No cheating this time."
"I don't cheat. The cards let me win." Izuku said with a grin.
"I'm onto you." Kyoka said suspiciously.
That winter...
Inko watched her son literally bounce off of all of the walls and ceiling for their apartment. "Sweetie I think you drank my espresso instead of your cocoa." She said as she tried to keep track of him.
"Whee!" Izuku said before he eventually crashed onto the floor. "That was neat!"
"I... need to see if we can find someone who can teach you how to do that better." Inko said "And someone to figure out how you can do that."
"Okay!" Izuku said with a nod. "I can make balloons explode now instead of just getting them to stick to me too!"
"Okay. I'll find a Quirk counselor for you if you promise to stop doing Three-Card Monte on the front step of the building." Inko told him.
"Why? I'm good at it. I even made a year's allowance from one guy!" Izuku asked her as he cocked his head to one side.
"Technically? It's illegal. Even if it is adorable." Inko told him. "Where do you keep getting those cards from anyways?"
"I know a street magician that owes me some favors." Izuku told her.
Inko shook her head. Despite having near constant supervision her son was truly capable of meeting odd people and getting into the oddest situations.
A quirk Counselor's office...
"Sorahiko... I gotta call in that favor you owe me." the Counselor said as he looked at the child who was frowning at him. "Well would you believe I owe gambling debt to a five year old? Yeah. I thought I could win but he beat me in poker. Eight times. Yeah I'll send you the details."
Izuku nodded at the counselor. "Thank you for being honest."
"Not a problem. How are you this good at card games?" The Counselor asked him.
Izuku shrugged as he managed to shuffle a deck with just one hand. "The cards speak to me some times."
"Have you ever tried any tournaments?" The Counselor wondered.
"NO!" Inko called from outside the office. "No professional gambling! He's five!"
A month later...
Sorahiko Torino, the semi-retired hero Gran Torino grinned as he watched the kid bounce around like the hyperactive knucklehead he was.
"So he started with static electricity he could charge up but now he's banking kinetic?" He asked Mrs. Midoriya.
"Seems that way. He's been able to magnetize a couple of paper clips and stunned a wild dog once." Mrs. Midoriya said. "The doctor we took him to said his Quirk might evolve but this is... different than anything my or my husband's family went through."
"Ooh!" Izuku said. "I made a paper clip explode yesterday!" Izuku called as he back-flipped off a wall.
Inko sighed causing Sorahiko to chuckle rather audibly.
"How do you guys feel about me coming over a couple of times a week?" He asked them. "I want to see how far this little tyke can go."
That caused Izuku to mess up a flip and he landed on the floor. "Really?" He asked the old man as his eyes seemed to sparkle.
"Sure." Gran Torino told the kid. "Did I mention that I was All Might's homeroom teacher at UA?"
Izuku's shriek of joy was so loud that he managed to break his mom's coffee pot.
A few years later...
"How did you manage to open the door?" Inko asked her son as he finished picking the lock to the apartment.
"Gran Torino has me learning how to pick locks. It's useful. I can even get out of handcuffs!" Izuku told his mom proudly.
"Why are you handcuffed?" Inko asked her son as she got a bad feeling.
"So they can't claim I'm cheating at Poker." Izuku said as he ran into the apartment.
"Izuku!" Inko said. "You're grounded!"
"Shows what you know! I can pick every lock in the apartment!" Izuku called as he started to hide in the ceiling tiles.
Inko sighed. Maybe she needed to take Gran Torino up on his offer of moving in. He had the space and seemed to get her son better than she did some days.
The Entrance Exam...
"I have weird feeling about that one." Toshinori Yagi said as he pointed at the photo of one teen.
"You should." Nezu said with a manic laugh. "Check out his home address."
"No." All Might said as he literally shrunk in on himself. "Are they related?"
"Not that I can see. He requested to be able to use a few support items and I allowed it." Nezu said.
"What is he using?" All Might asked.
"A slingshot, fifty marbles and two packs of playing cards." Nezu said with a cackle. "I told him he couldn't use his staff. I have to give the other kids a shot after all.
"This is a dangerous gambit Nezu." Aizawa warned. "He's a gonna be a handful."
"Oh, I know." Nezu grinned. "It's going to be great!"
TBC...
Yes, It's Izuku as Gambit.
