Lucia Caminos
Playable protagonist, and the first woman Rockstar has written as a fully voiced lead in a mainline Grand Theft Auto.

Lucia is the first woman Rockstar has written as a fully voiced lead in a mainline Grand Theft Auto. The first trailer introduces her leaving custody and picking straight back up with Jason.
She is consistently the one pushing. Where Jason reads as somebody managing his situation, Lucia reads as somebody trying to change hers.
In the screenshots
Her pages do a lot of the game's customisation work: changing haircuts, piercings, tattoo work, layered clothing including shirts tied at the waist, and in one shot a pistol wrapped in tape with a sticker on the body, which is the strongest hint yet at weapon condition being a tracked system.
