Experience Tumblr like never before
Realistically, given izuku never got one for all, he would have either entered UA through being in something other than the hero course (out of sheer luck), or gone through with what katsuki said and unalived himself shortly after.
If you wanna get deeper into that, no matter his character (Canon or fanon) bakugo would find out through inko or his own mother, that deku had unalived, and either,
1. Wouldn't care because, it's deku. He'd spent his entire life bullying him (very unlikeley)
2. Would care, so much so his mental health plummeted and he wouldn't get into UA (Again. Unlikely)
3. Care, get into UA, but not carry on with his bully personality, he would become quiet and distant, only talking when it was necessary or if towards a teacher. All might would still be in search of a successor, fuck knows who he would choose.
The fight between stain would end up completely different, some characters would be different, alot would change from the main storyline
Alot of this is me rambling since I haven't had any sleep for 12 hours but I just got into the show after abandoning it In like mid 2021 so take this all with a grain of salt
