Sometimes, Izuku wonders if Dabi was a sensei in his past life or something.

He gives good advice, and while he gives off the approachable older brother vibe, he also commands the sort of gentle but unquestionable authority that comes with hard-earned experience corralling unruly teenagers. He reminds Izuku a lot of Aizawa-sensei ' he 's not the type to give praise if it 's not well-earned, but he never discourages either. He 's all for constructive criticism ' although he tends to deliver it as backhanded compliments ' and is a big proponent of learning from mistakes.
