How many characters can you play as in gta v story mode?

Grand Theft Auto V's single-player story mode features three playable protagonists who switch between throughout the narrative. Michael De Santa, voiced by Ned Luke, is a retired bank robber living under witness protection. Franklin Clinton, voiced by Shawn Fonteno, is a street gangster seeking to leave his criminal past behind. Trevor Philips, voiced by Steven Ogg, is a violent drug dealer and gunrunner who was Michael's former partner. The game's structure revolves around these three characters working together on increasingly complex heists, with players switching perspectives during missions and story sequences. Players can freely roam the open world as any of these three characters outside of specific mission contexts, but there are no additional playable characters beyond these three protagonists in the main story mode.
