Robotbird is one of Professor Moshimo's creations and a one-time character that briefly appeared in the episode Tween for a Day, where he delivers the Exoskeleton based suit that allows Robotboy to look like a real boy. Like Robotboy, Robotbird has the desire to become real, as he sees a group of chicks being fed by their mother. He also has his own superactivate mode.
He is voiced by Rupert Degas.
- Unlike real birds that use their wings to fly, Robotbird flies with a propeller on the top of his head.
- He returned in Robotboy: Dawn of the Robot Clones
