Beep-0

Beep-O is an ally character introduced in Mario + Rabbids Kingdom Battle. He is a small robot with blue "eyes" and rabbit ears, and serves to guide the playable characters throughout the levels. Beep-O provides commentary throughout the game (with his color changing depending on its emotions), and is absent during battle sections. By default, Beep-O does not have rabbit ears; only gaining them after entering the Mushroom Kingdom.
