Boku No hero Academia I: because it deserves a thread.

[Drascin]

Alright if he can get up a vertical surface then it is a bit better than i remembered. Would make him a good firefighter/resque worker then.
But else, when his mobility is so bad he dont dare going that fast normally then i dont think its going to be of much use. I mean yes its going to be hard to hit him, especially if he is going away from you. But it will also be really hard for him to hit.

But that's the thing. He himself said that he doesn't dare go faster because he's afraid he might crash and he doesn't have enhanced durability. So:

- Gentle-man could go faster, he's just scared to do so.
- Training to improve his reflexes and maneuvering could make him much better at avoiding a crash, and therefore make him more confident to push his speed further.

I mean, it's not a top tier quirk by any means, but there's a fair amount of potential in the ability to just zip on the ground and on walls as fast as a car, and it's not like there's not a bunch of heroes with also pretty middling-seeming quirks.
