Companions are a special NPC type in Code Vein, that joins the player and forms a party to adventure out in the field. Companions can be recruited as the game progresses, and only one of them may be active at a time. Companions are optional but helpful in a battle as they are capable of flanking your enemies and taking on a support role by healing and buffing your character as well as enabling a special duo Hemorrhage ability that you can perform together.
Your companion can also be your blood bag, meaning you can suck up their blood for yourself should you need to. They are also at risk of being incapacitated in battle and would have to be revived at a checkpoint. Though your companion can't be controlled directly, a set of predetermined orders can be given such as: Guard and Retreat commands. You cannot customize the weapons of Companions, they all have a unique specialization and associated strengths and weaknesses.
