Are there any missions in gta online that involve michael or trevor?

Grand Theft Auto Online is a separate multiplayer experience from Grand Theft Auto V's single‑player story mode. The game does not feature missions that involve the main protagonists Michael or Trevor from the narrative campaign. All online missions and content are designed for player-created characters, and the game’s storyline is distinct from the single‑player plot. Therefore, no missions in GTA Online include Michael or Trevor as characters.
