Total Overkill

Completely Unnecessary Big Oof.

A Total Overkill is a murder (or simply just a removal) of a character that happens in a way that's completely over the top and needlessly gory or celebrated by their enemy or someone on the enemy's side. This can be achieved by doing 9999 DMG to somebody to make sure that they're dead and have less than no chance of surviving the finishing blow. Somebody who was a long-time or deeply-hated foe might receive this treatment when their enemy gets the chance to serve them with it right along with Throwing Salt On The Wound over or around their body.
