– Bag-Headed Cashier to Knightbrace
The Bag-Headed Cashier is an employee at the Villain Supermarket. He is very unenthusiastic about his job.
He first appears in Operation: M.U.N.C.H.I.E.S. offering Knightbrace a membership deal, but the conversation is broken up by Father. In the end, he shares in eating the Rainbow Munchies with both Sector V and the adults.
He also makes a minor cameo in Operation: Z.E.R.O., transformed into a Senior Citizombie by Grandfather. He was seen attacking Numbuh 23 with the zombified janitor on one of the streetlights on the KND Moonbase bridge.
