Vore

This character swallows or eats someone alive in a sexual scene, the victim can both die or survive the act for this trait to apply.

Vorarephilia is a sexual fetish and paraphilia where arousal occurs from the idea of being eaten, eating another, observing this process, or by the general process of eating. The fantasy most frequently involves the victim being swallowed alive, and may or may not include digestion.

If the character eats, swallows, or cannibalizes in a non sexual way, just use cannibalism instead.
