Pyrobots are Ready-Bots that appear in the Factory world of Donkey Kong Country Returns. There are two types of Pyrobots, both of whom patrol a set area back and forth and occasionally release from their arms like a flamethrower before resuming with their march. If Donkey Kong and Diddy Kong come in contact with the fire, they get burned and injured.
The red, older Pyrobot Mk I (also spelled Pyrobot Mk 1) is invulnerable to every attack from the Kongs themselves. However, they can temporarily immobilize a Pyrobot Mk I by jumping on it. A Pyrobot Mk I can only be defeated if the Kongs throw a barrel or a BuckBomb at it.
The yellow, newer-looking Pyrobot Mk II is less durable and can be jumped on three times to be defeated. The Kongs can throw a barrel at a Pyrobot Mk II to instantly defeat it.
