In all games except for Mount and Blade II: Bannerlord companions cannot be killed. Like the player character, heroes never die and are only knocked unconscious. Heroes or companions are unique troops with individual names, stories, skills, attributes, and equipment (all of which can be chosen by you). For the heroes featured in Bannerlord, see Companions (Bannerlord). For the heroes featured in Viking Conquest, see Heroes (Viking Conquest).
For the heroes featured in Mount&Blade: With Fire & Sword, see Heroes (With Fire & Sword).
