Battle Beast (Thokk from Invincible) once killed a Viltrumite (The setting's equivalent of Saiyans or Kryptonians) and partially devoured him while he was floating in space. There was nothing else to eat, after all.

He is the sort of pred who would be extremely disappointed if you didn't put up a fight while you were being digested. If he could swallow a Viltrumite whole he'd do it in a second just for the post-gulp antics.

In the comic he's plantigrade and has no tail, but I wasn't having any of that. Lion men should always have a tail. They look weird without them, just as WoW Worgen look all wrong without a wolf tail.
