Suicide Bomb is a Quirk that is used by an unnamed Villain in My Hero Academia: Vigilante.

Description
Nothing is known about the exact functions of this Quirk. However, as it's name suggests, this Quirk seems capable of creating huge explosions that surround the user and destroy their surroundings.

Endeavour's Hell's Flame Quirk was described as the worst matchup against this Quirk, which implies that it can be set off from outside sources as well as it's users will.

It is also implied that this Quirk can kill it's own user.
