Living Explosive Individual

It’s has been stated that the most dangerous weapon that anyone is the person themselves as they tend to be unpredictable. This makes sense in battle, yet who's going to sign up? This can pose a problem, even with a fail-safe system in place.

In the case of this trope, the user would explode, for real. It’s possible that one part of the body can be the explosive. In some instances, this could be a straight suicide mission or have a way to resembled after such use. This can also be the result of by nature, and the being could have a way to regenerate their bodies as much fail-safe. In any matter, if this fellow shows up, it’s set not to set them off.

Supertrope to Why Am I Ticking? (where the person doesn't want to blow up) and Action Bomb (where the person blows up intentionally).

This is mainly due to cases of people and even animals being used as living bombs, mostly in Suicide Attacks, as it's highly controversial.
