Bjornbot

Bjornbot is the creation of Bjorn Bjornson, Bjorn wants him to be the greatest fighting robot in the world, due to jealousy at Robotboy. Bjornbot can be considered the antithesis to Robotboy (apart from Protoboy), who he has a deep rivalry with, (apart from Protoboy) he is evenly matched with him, and has a super activation mode aswell, he rarely speaks apart from single words, grunts and saying "yaaa!".

It was revealed in his debut, he had two copies, but he and they were all destroyed at the end of the episode, Bjorn said he would make another Bjornbot at the end, implying the one seen in future episodes is a replica.
