Are michael and franklin available as downloadable content in gta online?

The Wikipedia entry for Grand Theft Auto V lists Michael De Santa and Franklin Clinton as the main protagonists of the single‑player campaign, describing their roles in the story. It does not refer to them as downloadable content or mention any separate DLC that would add them to GTA Online. Therefore, based on the available evidence, they are not available as separate downloadable items in GTA Online; players can access them as part of the standard game.
