Can players in gta online complete objectives alongside story mode characters?

Grand Theft Auto Online is a separate multiplayer component from Grand Theft Auto V's story mode. While both games share the same fictional world of San Andreas and Los Santos, Online does not allow players to interact with or complete objectives alongside the story mode's main characters—Michael, Franklin, and Trevor. Instead, Online features a customizable silent protagonist that players create and develop independently. The game's cooperative modes, such as heists and missions, involve collaboration with other human players rather than story mode characters. Although some downloadable content (DLC) updates have introduced limited appearances or references to story characters, these are typically non-interactive and do not enable joint objective completion. GTA Online's design emphasizes player-driven progression and social interaction within its own narrative framework, distinct from the single-player story's predetermined plot and character arcs.
