Deku the One For All Legend (Bnha multi crossover fanfic)

Before the entrance exam

    It's been three years when Izuku's Dad came home but sadly had to leave for Gotham again. But after everything, everything was looking up for the Midoriya's! Thanks to the friendship that Izuku and Trunks developed along with Goten, Bulma decided to offer a job to Inko, and she happily accepted. Inko made enough money that she decided to move out of the apartment and into a nice house out in the country in Japan! The best part is, Inko works from home so she can take care of her growing Son Izuku. Of course, not everything can be all sunshine and rainbows. When Izuku was twelve years old, he had found out that his Father Hisashi had been killed by a villain while he was on duty. He was heartbroken to hear this and fell into depression. He promised that he would be a great hero just like him and All Might. Toshinori helped Izuku cope with his loss. He was getting stronger thanks to Goku and his other friends. Izuku got strong enough that he can actually spar against Goku, Vegeta, and even Broly all at once! He actually gained the respect from Vegeta and he started calling Izuku 'The Saiyanot', Izuku was happy about the nickname he got and of how far he's gotten thanks to his new friends. Of course as Izuku got stronger and stronger, so did his two half Saiyan friends. Izuku would spar with both Trunks and Goten in Vegeta's gravity room. He was happy that he had two friends that actually wanted to be friends because of him and not because of his title that he's been known for, of course, both Trunks and Goten still give him the nickname Bomb Shelter, but that's just because they liked the nickname. Trunks and Goten respect Izuku as a friend, both of them know that they all have the same goal and that's to become a hero.

    It was a school day and Izuku was writing and mumbling into his journal like usual. His thoughts were cut off by the teacher that walked in.
"Alright, the end of your middle school years are coming to an end. So that means you guys are gonna be writing down your career paths." As the teacher says this everyone groans and moans.
"But I already know you all want to be heroes so that's just useless!" The teacher says throwing the papers around. At this everyone gets excited showing off their quirks.
"Now now! I know you're all excited, but you all know you're not allowed to use your quirks in class!" "Hey teach! Don't lump me down with these extras! I'm the one that'll be the greatest hero of all time!" Katsuki says in his arrogant tone.
"You think you're better than us all!?" A random kid said.
"Come one! I'll take you all on!!!" Katsuki says creating small explosions in his palm.
"Oh yeah! Bakugo, you're applying for UA, am I right?" The teacher said.
"UA! Isn't that for the best of the best?" "Yeah! It has a very low acceptance rate as well!"
"Oh yeah! Midoriya, aren't you also applying for UA?" The teacher said as everyone looks back at Izuku.
They weren't very surprised. They all knew Izuku's title known as Bomb Shelter, all he could here were the whispers around him saying; "Yeah, he's definitely getting in!" Not to mention, he's only gotten stronger! He has quite a bit of muscle on him though he looks slender in his uniform. Everyone was looking at him amazed that a quirkless kid has gotten this strong, or so they think he's quirkless. One certain blonde was looking at him with nothing but hatred. Izuku swore he saw his palms hold explosions on his desk.

After the bell rang and the school day ended, Izuku was usually the last one out seeing he's usually lost in thought in his notebook. His thoughts were interrupted by a hand swiping his notebook. "Hey, Kacchan that's mine!" Izuku yelled.
"Like I give a damn Deku! Look! You better not get into UA or i'll kill you!" Kacchan said as he blew up his notebook and tossed it out the window.
"Kacchan! Why are you so mad at me that you decided to destroy MY notebook!" Izuku yelled.
"Deku! Ever since that damn explosion, you've done nothing but look down on me and steal my spotlight!" Katsuki yelled trying to burn Izuku's shoulder.
"Look! Kacchan! I don't care about popularity, and I sure as hell don't care about your 'spotlight'! Please! I'm sorry! I... just want to be friends again..." Izuku said with tears stinging his eyes.
"Hmph! If you want me to forgive you, i'll tell you how! You can fly, right? Pray I'll forgive you in your next life and fly up to the sun!" Katsuki shouted before storming out.
Those words hit Izuku like a truck. If he wasn't depressed before, he is now. He had his hair covering his face and shortly after Katsuki was out of sight, Izuku slowly walked out of the building.
