You've got to be kidding me. Ward? What a pain in the ass. Leaving him dead on another planet isn't enough to get rid of that guy.
~ Alphonso Mackenzie on Hive using Grant Ward's body as a vessel after his death.

Villains who died and have remained dead, yet continue to have a lasting impact and presence from beyond the grave in an earthly and terrestrial way. They can even be dead from the very beginning of their stories and appear primarily in flashbacks (like Bertrand Zobrist). Their actions in life (including their involvement in villainous events), their legacy, and the harm they caused may continue to have a lasting impact after their deaths.

Note: Villains who have come back as ghosts, zombies, vampires, etc. usually cannot be posthumous as well (as their actions are still being carried out by their undead forms) UNLESS:

  1. Their undead form is also killed off (this time permanently), and they have a posthumous effect after that (i.e. Shane Walsh).
  2. Their undead form disappears or removes itself from the action and no longer connects with the plot, essentially being permanently removed (i.e. Darth Vader).
  3. Their undead form is defeated and sent to (or back to) an afterlife or Hell dimension where they can never return.
