Izuku is all might's son. But izuku didn't get a quirk, but his sister got a super strong quirk that rivals all might's. Izuku gets ignored by his parents to train her, his mom, the number 11th her magnet, has also trained with her, but also helps izuku so he can defend himself. But after working out over and over again, no muscle came on him and his mother thought he wasn't even trying so she gave up on him, but still loved him. After his mother gave up on him, izuku was in a pit of rage and hit a wall really hard in abandon part of the city. The wall he hit broke, and izuku stared in awe of the destruction, then it hit him that it must've been his quirk. BUT it really isn't... i don't own Bnha!!!! I DON'T OWN MHA
