Beast is one of two categories of Companions that includes Kubrows and Kavats, with the other being Robotic that includes Sentinels and MOA. A distinctive feature from robotic category is the need for daily maintenance which, if skipped - will cause a deterioration in the beast's performance. Additionally, there are mods that can only be equipped by this category of companions. If killed in a mission, beasts (and robotic MOAs) can be revived infinitely, unless their bleedout timer runs out, in which case they will automatically revive after the owner is killed and spends a revive, or always in the next mission.

Main article: Kubrow

Kubrows are terrain-restricted melee canine companions. Kubrows behave similarly to NPC allies (i.e. specters) as they will stay within close proximity of the player while fighting alongside them and will enter bleedout states when they are downed, from which they can be revived. Kubrows require constant care and maintenance but are more durable than other companions like sentinels. Incubated Kubrows can sport different permanent features such as species, height, and eye color, as well as customizable features like fur color and cur pattern. There are currently 6 species of ownable Kubrows, each with different stats and abilities.

Kavats are terrain-restricted melee feline companions similar to Kubrows. Reviving Kavats in missions is similar to reviving allied Tenno. Kavats require constant care and maintenance but are more durable than sentinels. They also have different breeds, color palettes, and patterns. There are currently three types of Kavats.
