Do gta v story mode characters appear in online mode?

The cited Wikipedia article focuses on the development history of Grand Theft Auto V, including its release dates across platforms and the team at Rockstar North involved in its creation. It mentions the game's spiritual successors like Red Dead Redemption and Max Payne 3 but does not address gameplay features such as crossover appearances between story mode and online mode. To determine if story mode characters like Michael, Trevor, or Franklin appear in GTA Online, additional sources detailing the game's online mode features would be required. The available evidence does not support a conclusion on this specific question.
