Can you play as michael trevor or franklin in gta online?

Trevor Philips, one of the three protagonists of Grand Theft Auto V, is available for play in the game's multiplayer component, Grand Theft Auto Online. The Wikipedia article confirms that Trevor appears in GTA Online, presenting him as a career criminal who runs his own organization and engages with rival gangs. The article notes that Trevor is one of the three playable protagonists alongside Michael De Santa and Franklin Clinton, but it does not specifically state that Michael or Franklin can also be played in GTA Online. Consequently, based solely on the available evidence, only Trevor's availability in GTA Online can be affirmed. No reliable source in the provided excerpt indicates that Michael or Franklin are playable characters in the online mode.
