Does gta online include characters from gta v?

Grand Theft Auto Online is the online multiplayer component of Grand Theft Auto V, developed by Rockstar North and published by Rockstar Games. The Wikipedia source identifies the game as set within the same fictional state of San Andreas, featuring the open‑world environment of Los Santos. While the game shares its world with GTA V, the provided text does not mention whether the specific characters from the single‑player storyline of GTA V are present or playable in the online mode. Therefore, based solely on the cited evidence, it cannot be stated that GTA Online includes characters from GTA V.
