Yes -- It's Bitner, Your Dead Partner

Brain-Bat: Init +4; Atk claw +0 melee or bite +2 melee (1d3) or psychic blast +3 ranged (1d6); AC 10; HD 1d7+1; MV fly 40’; Act 1d20; SP control corpse, psychic death throes; SV Fort +0, Ref +2, Will +15; AL C.

A Brain-Bat can slip onto a corpse and wear it like a zombie. Treat the corspe as a Zombie (DCC core rulebook, page 431), except that it attacks with a claw (1d4) or a weapon (by weapon type).

When a Brain-Bat is slain, its wail of psychic distress affects all living creatures within 100'. These must succeed in a DC 15 Will save or take 1d3 points of temporary damage to both Intelligence and Personality. On a natural "1", one of these points is permanent (player may choose which).

Brain-Bats are extremely intelligent. They can use corpses to speak when riding on one, and use both the living and the dead to further their schemes.
