Can i use michael de santa as my avatar in gta online?

Grand Theft Auto Online is the online multiplayer component of Grand Theft Auto V, developed by Rockstar North and published by Rockstar Games. It allows players to create and customize a silent protagonist who can roam the fictional state of San Andreas. The game’s character creation system provides a variety of appearance options, but the main protagonists of Grand Theft Auto V—Michael De Santa, Franklin Clinton, and Trevor Philips—are not listed as selectable characters in the online mode according to the source. While players can tailor their avatar’s look, the game does not feature a direct option to play as Michael De Santa in online play. Therefore, based solely on the provided evidence, there is no confirmation that Michael De Santa is available as an avatar in GTA Online.
