Do the main characters of gta v exist in gta online?

Grand Theft Auto Online is a separate online multiplayer component of Grand Theft Auto V that allows players to create a customisable silent protagonist. The official description of GTA Online does not mention the three main characters of the single‑player story—Trevor, Michael, or Franklin—nor does it provide any indication that they appear in the online mode. Instead, the online experience focuses on cooperative and competitive gameplay with user‑made characters, missions, and activities. Because the Wikipedia entry on GTA Online contains no reference to the GTA V protagonists, we cannot confirm their presence in the multiplayer setting. Thus, based on the available information, the main characters of GTA V do not exist within GTA Online.
