Can you use your story mode character in gta online?

Grand Theft Auto Online operates as a standalone online component of Grand Theft Auto V, with its own distinct character creation system. While the single-player Story Mode features predefined protagonists like Michael, Trevor, and Franklin, GTA Online allows players to create and customize their own silent protagonist. The Wikipedia evidence confirms that GTA Online's open-world experience centers on this custom character, with no mention of transferring or using Story Mode characters. The two modes are designed as separate experiences with different character progression systems, meaning choices in one do not carry over to the other.
