Can gta online use characters from the single player campaign?

Grand Theft Auto Online is a distinct multiplayer component of Grand Theft Auto V that runs on its own servers and allows up to thirty players to create and customize a silent protagonist. The online game has its own character creation system and does not import or use characters from the single‑player storyline. Because the Wikipedia entry for GTA Online only describes its multiplayer features and no references mention character transfer between modes, we cannot confirm that such functionality exists. Consequently, based on the available evidence, the answer is no, GTA Online cannot use characters from the single‑player campaign.
