Note: In this universe, Deku decides that being a sidekick was more than enough for him (don't worry y'all this is for his character development ;)
Ever wonder why Bakugo really hates Izuku? Was there a proper reason for him? Or was it because he was hiding something?
*10 years ago*
"Katsuki let's go!" cried a kid that was waving at the young blonde.
"You guys go on ahead." He told the group of kids, they all looked at him and one of the kids started to snicker.
"Come on guys, let's let Katsuki and his cripple friend." That was probably the first time Bakugo ever popped a vein. He was so angry at the kid. How dare he mess with his bestfriend!
"HOW DARE YOU!" a little kid like Bakugo at the time, punched an older and much bigger kid, all for the sake of Izuku…
Eventually the bunches of kids piled up and became too hard for Bakugo to handle alone, and like the dork his friend was, Izuku summoned up what little courage he had and flew straight right in the fray of kids. He was indeed quirkless, but Bakugo still taught him how to throw a punch.
"Kacchan!" screamed little Izuku as they fended off the kids. Bakugo was shown to have multiple scratches and bruises here and there, but Izuku looked far worse. His curly hair was disheveled, his eyes a little bit swollen; his knees scraped with a bit of blood trickling down and on top of all that, his tears were already threatening to spill.
"Kacchan… *urk* *urk* we did it!" Bakugo couldn't remember the last time he felt that angry. For a weak and frail boy like him to throw himself into the fray for his sake, that's why he took a silent vow that he would make Izuku strong even without having a quirk.
"Izuku… Listen to me, if we continue to be friends you'll only end up hurting yourself more." He told the younger boy with a sad smile on his face.
"B-But Kacchan- *urk* *urk* I don't want to lose a friend! You're my first friend!" here come the water works… Bakugo winced at the sight of Izuku crying his eyes out.
"O-oi don't cry! *sniffle* All Might wouldn't cry!" He shouted, pointing at Izuku who quickly wiped his tears and snot.
The walk home was really quiet this time. The two boys stopped by a river and set down their bags on the soft grass. This was their special place, Izuku's swollen eyes had gone back to normal after their quick stop earlier at a convenience store to buy band aid's and a cold compress.
"Izuku, you have to be strong. And those bullies won't stop picking on you if you act like a wimp all the time." Izuku looked back at him with wide eyes.
"Yeah… But I'll never be as strong as you Kacchan… I'm quirkless." He sighed and crouched down the bed of soft grass. Bakugo then took out a small notebook from his back and handed it to Izuku.
"Here. You're really sure that you don't want to be a hero?" he carefully asked Izuku, who gulped and weighed down his options.
"Kacchan… I can't be like All Might…"
He knew it, his friend was still afraid. Why did it have to be so unfair? Why did Izuku have to live his life without a quirk? It was so freaking unfair! He thought. He looked at Izuku and saw that a new smile formed on the quirkless boy's face.
"But! I'll be the best sidekick the world will ever see!" He was taken aback, sidekick? But then, that would mean…
"O-oi are you serious about this? I-If you're going to be a sidekick, you'll have to be mine! Here, here, on this notebook you scribble down all the bad guy's weakness and what I can do to defeat them! Deku! This is perfect!"
"W-what did you just call me Kacchan?"
"Deku! It's perfect! It means 'I can do it!' we'll be the best duo U.A will ever see!" the two boy's laughed their heads of, already they scribbled down what their costumes would be like, which HQ they would like to be assigned on, and Izuku even picked Bakugo's hero name: Spitfire!
"Spitfire?" Bakugo tested as Izuku explained to him that Spitfire was a cool name, perfectly matching his quirk. With a grin, the young Bakugo jumped in excitement, adrenaline rushing in between the two boys.
"Then it's settled! Deku! First thing tomorrow we'll start our training!" Bakugo ordered sternly, he and Izuku were now determined to be the best crime fighting duo. Even heroes need help, just because someone doesn't have a quirk doesn't mean they can't help people with quirks.
"Yes sir!" saluted the young Izuku, the two boys then marched home, excited with their newfound dream. Bakugo's parent's apparently had business to attend to the next morning, so they left him with Izuku's mom. The two boys spent the entire night watching hero videos while Bakugo noticed that Izuku really was determined to analyze heroes and the villains.
"No bad guy will ever threaten our city anymore, hero Spitfire!" beamed Izuku with a bright smile to his friend.
"You know it! We'll be the best duo there ever was Deku!"
- End
Welp, that was already a chore to write. Anyway I hoped my writing skills didn't rust that much guys, I hadn't been writing in ages, probably three months out of action now. I hope you would leave a review! Thank you once again for reading!
