I Do not own One piece or My Hero Academia or their characters

That right belongs to Eiichiro Oda and Kōhei Horikoshi

Except for my OCs

There will reference from other anime and shows that I also don't own.

CH. 0 Here's the Portagas D. family

"Come on daddy," said a child 4-year-old boy

"Alright Izuku," said the father

"Whoa does your mother know about this video?" said the father

"KNOW ABOUT WHAT?" said an angry mother

"AHH! BONNEY/MOMMY!" yelled Izuku and his dad

"PORTAGAS D. ACE WHAT ARE YOU SHOWING OUR SON?" said Jewelry Bonney

"Um showing that video with All Might first appearance," said Izuku

Bonney's rage cools down and realized that "Fire Fist Ace" just got back from visiting Grandpa Whitebeard.

"Oh, why didn't you say so? Come on aren't you and your father late for Bakugo's birthday party? "said Bonney

"Oh, you're right quick to the flame bike (Striker)." said Ace as he and Izuku ran off while taking some food and ran to the motorcycle.

Minutes later

"Just be careful you two," said Bonney

"Don't worry I'm a part of the Whitebread pirates I'll be okay, and I'll take care of our son." as he kissed Bonney, he left with Izuku in a sidecar.

An hour later at the halfway point to the party location Ace and Izuku had a fateful encounter that would throw the whole world upside down.

BOOOOOMMMM!

"Daddy what's happening?" Izuku asked as he was scared

"I don't know huh?. What the? YOU!" said Ace with hate

"Zehahahahahaha!" the "unknown" attacker laughs.
