One-armed ghoul

This one-armed ghoul is encountered by the Puppet Man during his adventures. Given that he wears (what is left of) a Vault suit, he was probably originally an inhabitant of either Vault 12 or another vault that suffered a similar fate.

When the Puppet Man tells about how horrible it was to live alone in a vault full of puppets, the ghoul says that his own vault "coulda been better".

Appearances
He appears only in strip #9 of the official One Man, and a Crate of Puppets comic by Penny Arcade.
