BNHA theories (Original Theories)

Bakugou and Deku theory

BakuDeku theory

The real reason bakugou hurt/pushed Deku away

My original theory

Bakugou gave deku the name deku because he thought that if he was called worthless he would be worthless and bakugou would have to protect deku then. He bullied deku because he thought that if deku kept trying to be a hero without a quirk he would die or get hurt. He was mad when deku got a quirk because that means bakugou didn't need to protect deku anymore. Bakugou kept being mean to him even in UA because of how the quirk effected deku and the fact that they would have to fight and hurt each other if they both stayed at UA. He was mad at allmight for giving deku the quirk not because he was jealous but because he didn't want deku to break himself just for a dream that might not come true or get deku killed and that's why bakugou is willing to break himself so he could be stronger than allmight and be strong enough to protect deku. 

Another theory I have on this topic is what if Bakugou's quirk was hard to control as a kid blowing up everything he touch and so he pushed deku away to protect deku from himself but because bakugou has a hard time expressing his feelings whenever deku kept trying to chase after bakugou he got mad and let his anger out on deku un intentionally hurting deku because he was never taught how to control his emotions and as time went on that's the only way bakugou knew how to express him self. But when they entered U.A bakugou realizes what he had done to the person he was originally trying to protect and found himself unworthy to stand by Deku's side or try and befriend him so he kept his mean persona and did what ever he could to be better then deku hoping the guilt would go away.
