Do gta v story mode characters appear in online?

The verified evidence describes Grand Theft Auto V's single-player story mode, detailing its three protagonists—Michael De Santa, Franklin Clinton, and Trevor Philips—and their involvement in heists within the fictional state of San Andreas. However, the evidence contains no information about Grand Theft Auto Online or its interactions with these characters. Rockstar Games' GTA Online operates as a separate multiplayer experience where players create custom avatars and pursue independent objectives, though it occasionally includes references to the main story's events or locations. The absence of any mention of Online in the provided source means no definitive conclusion can be drawn about character appearances based solely on this evidence.
