Flexboy was an automation created by one of the Nameless Fiends. It participated in the Chat Tavern before the Successor Slam. It was able to blend in with the locals even though it was incapable of speech or thought. Flexboy communicated entirely through the use of flexing, whom patrons of the Chat Tavern understood perfect through the beauty of Universal Flexing Language.

Eventually, records of the Flexboy became lost to time. According to historians, the Chapelpeople resolved to burn all records out of mega embarrassment upon realizing they were flexing back to a machine.
