Villains who have faced an unknown fate and are thought to be dead, though their deaths were left unconfirmed. Alternatively, they have died in conditions where it is implied that they could still be alive.

Villains in this category were last seen in situations that they were not expected to survive, but given that they either were not seen dying, or their bodies or remains were not found anywhere, they could possibly revive in the future or might still be alive and plotting a return. Yet, their fates and statuses are currently unknown.

These villains do not count as Karma Houdinis unless the presumed death was of natural causes (e.g. Toplofty and O'Bloat, Donald Love, Mr. Grasping, Warren T. Rat, Orca, and Nefretiri) or if they’re more likely to have survived and escaped rather than died (e.g. Rasmin Yelkov, Flumpty Bumpty, and Tord).
