My favourite villain boi. He hasn’t been properly introduced here yet so here’s a short summary of his story:
He has a chip implanted in his neck by All For One to make him insane. He was told to bring down the number one hero ‘Endeavor’. Halfway through his fight he became too weak, Endeavor managed to burn the whole of his left side. All For One took a liking to this ‘Villain Yagi’ and favoured him over Shigaraki. Shigaraki grew jealous and attacked him, stabbing his right eye. One For All still works with Toshinori. As well as the fire and healing quirks he was given.
