My brother has this figurine of a six-armed woman with blonde hair. It also has the numbers 101 on its back. I have no idea whether it is from a game or show. Does anybody know anything about this?
Vault Boy is a mascot character of the Fallout series. In Fallout 3 it also appears as a perk tree character, as pointed out by Dpeif. You can collect those bobble-heads for your collection, although I've never seen a female one before.
Number 101 is the number of the Vault where the protagonist of Fallout 3 hails from.
