Can i import my custom character into gta v campaign?

Grand Theft Auto V’s campaign mode uses a fixed protagonist, Trevor, Michael, or Franklin, whose appearance is set by the game and cannot be altered with a custom avatar. The only place in the game where players can create or import a unique character is Grand Theft Auto Online, which is a separate multiplayer component. In GTA Online, players can customize a silent protagonist with a range of cosmetics, but this character exists only within the online world and cannot be transferred to the single‑player campaign. Therefore, attempting to import a custom character into the campaign is not supported by the current game mechanics.
