The main protagonists of Borderlands 2 are Axton, a renegade soldier (Robert McCollum), Maya, another Siren (Martha Harms), Salvador (John Swasey), a short-statured and short-tempered "gunzerker", and Zer0, an enigmatic masked assassin (Michael Turner).
All but two of the player characters of the Pre-Sequel appeared in earlier games as NPCs.
