I vaguely recall a reboot Twilight Zone or reboot Outer Limits where a rich woman paid a doctor to keep her alive by any means necessary, and ended up being just a head on a pedestal with one robot arm, that was limited in its range of motions such that it could not aim a gun at the head. And also In Fallout 4: Nuka World, where the Walt Disney expy character was just an immortal head in a tiny Vault-Tec bunker.
