[He's talking to a guy who's a walking bomb. Vash being a plant-shaped nuke doesn't determine who he is or what he can do. Use both plant and nuke facets to help people and he's as much a hero as Bakugo and the others in the blonde's world. At least that's how Bakugo will look at it.

Even if Vash having a running Quirk would be kinda hilarious, given how gangly he can look while running.]

Quirks are individual. Some families can pass down similar or the same Quirk. My classmate's Quirk gives him engines in his calves; his brother's Quirk is the same, but his engines are in his elbows.
