The Operator is one of the nine NPCs introduced in the AlchemistNPC mod. She can be named Angela or Carmen.
She can move into an empty house after the Eater of Worlds / Brain of Cthulhu has been defeated. to make a house make a rectangle with a chair table and light.
She sells boss drops and some special EGO equipment. While in Expert mode, Vanilla and Modded Treasure Bags are also present in her shop. She will help you open the Xenomorphic Mystery Meteorite (obtained with a 20% chance per Blood Moon).
She drops the APMC, also known as the AI Programming And Memory Chip, which can be used to spawn her back in if killed. The tooltip of the APMC will reference the name of the previous Operator, and when used it will spawn her back in with the same name.
