Can i use my online character in single player?

Grand Theft Auto Online is the multiplayer component of Grand Theft Auto V and runs as a separate game mode. It allows players to create and customize a silent protagonist for online sessions, but this character data is stored only for the online environment. The single‑player campaign of Grand Theft Auto V uses a fixed set of story characters and does not support importing or using the online character. Consequently, progress, appearance, and inventories from GTA Online remain isolated from the single‑player experience.
