Plastic Surgeons are NPCs who have a chance of spawning at any bars. In exchange for 200 cats, the character editor will be re-activated, allowing the player to make changes to existing character including a new name.
There is a similar NPC named Guild Plastic Surgeon found at Shinobi Thieves towers, who will provide the service for free, but only to members of the guild.
They wear [Shoddy] armour (5% chance of [Standard]).
