What are the main characters in grand theft auto v story mode?

The Wikipedia excerpt focuses exclusively on Grand Theft Auto Online, describing it as an online multiplayer action-adventure game released in 2013 and expanded to newer consoles in 2022. While it mentions that players control a customizable silent protagonist in the online mode, it does not provide any details about the single-player story mode characters of Grand Theft Auto V. The main characters of GTA V's story mode—Franklin Clinton, Michael De Santa, and Trevor Philips—are not referenced in this source. Since the evidence is limited to the online component and lacks specifics about the narrative cast, no verified character names can be extracted from the provided material.
