Ker and Beus (called Keru and Besu in the English dub) are Ken Midori's two canine puppets that he uses to communicate with due to his shy personality. They first appeared in epsisode 2 of Beyblade Burst. Their names are a reference to the name of Ken's Beyblade, King Kerbeus, each of them having one of the syllables as its name. Ker and Besu each represent a different side of Ken's character.
