Monkey Island 2: The Two Chesters 

Chester, the less-than-friendly helpline technician in the Dinky forest, was modeled after Khris Brown who got her nickname from Tim Schafer. According to the Special Edition commentary, the in-game character’s to-the-point attitude was based on Tabitha Tosti, who Tim sat next to at LucasArts.
Chester was replaced by a male technician in the Special Edition.
