Can i access gta v story mode characters online?

Grand Theft Auto Online is the multiplayer component of Grand Theft Auto V, released in 2013 as an expansion of the original game. The evidence specifies that it allows up to 30 players to explore the open world of Los Santos and San Andreas, engage in cooperative or competitive modes, and control a customizable silent protagonist. However, the evidence does not mention whether the story mode characters—Michael, Franklin, and Trevor—from the single-player campaign are playable or accessible in GTA Online. Without explicit information confirming or denying their inclusion, no definitive answer can be provided based solely on the verified evidence.
