Jason Duval is the other confirmed playable protagonist of Grand Theft Auto VI. Rockstar publishes his full name and biography on the official GTA VI site and centers Trailer 2 on the pair’s criminal partnership.
The official copy is spare. He grew up around grifters and crooks, did a stint in the Army after troubled teens, then ended up in the Leonida Keys working for local drug runners. Rockstar says it might be time to try something new — without listing employers, ranks, or a rap sheet.
On Lucia, Rockstar is deliberately unresolved: meeting her “could be the best or worst thing to ever happen to him.” Map-6 will not turn that line into a betrayal theory, a marriage plot, or a GTA V-style switch tutorial. Those details are unconfirmed.
Trailers show Jason in the Keys, on the road with Lucia, and in Vice City set pieces. That is evidence of setting and pairing. It is not a vehicle roster in his name, a safehouse address, or a skill tree.
Use this entry as a sourced stub: who Rockstar named, what Rockstar wrote, and which official videos put him on screen. When Newswire or rockstargames.com/VI add more, this page should grow. Until then, the honest list stays short.
