Can i use gta v protagonists in gta online?

Grand Theft Auto Online is the online multiplayer component of Grand Theft Auto V, but it does not provide playable versions of the game's main characters. In GTA Online players create and customize their own silent protagonist, and the game focuses on cooperative and competitive modes rather than the single‑player storyline. Because the provided information does not mention the protagonists from the single‑player campaign being available for use in the multiplayer environment, we cannot confirm such a feature exists. For official details on character availability, checking Rockstar Games’ support or community forums would be advisable.
