Billy
RumorCharacter mentioned in a leaked development menu (unconfirmed)
"Billy" is a character name spotted in a leaked GTA 6 development menu, alongside "Kai" — suggesting an original four-protagonist project later scaled down to two (Jason and Lucia). Rockstar Games has never confirmed this character.
According to several gaming outlets, a leaked development menu listed four playable character names for GTA 6, including "Billy" and "Kai", alongside the ones that became Jason Duval and Lucia Caminos.
This leak suggests Rockstar Games may have originally planned a four-protagonist project before scaling it down to two. No information about Billy's role, appearance, or story is available beyond the name itself.
Rockstar Games has neither confirmed nor commented on this leak. The character may have been cut during development, or could resurface in another form (additional content, for instance) — neither hypothesis is verifiable at this stage.
