Orbot is a diminuitive assistant robot created by Dr. Eggman and has appeared in a number of Sonic the Hedgehog titles. Usually accompanied by fellow robo-lackey Cubot, Orbot's job is to keep Dr. Eggman informed of the progress of his schemes as well as perform menial tasks such as preparing the doctor's meals or operate certain machines.
Orbot has a calm and soft-spoken demeanour most of the time. He can be very passive-aggressive and often talks back to Dr. Eggman and points out flaws in the doctor's schemes. Despite Orbot's insolence, Dr. Eggman still keeps him around, perhaps out of loneliness more than anything else as the doctor spends very little time with people.
Orbot usually speaks in a calm, collected manner. While he never outright disobeys Dr. Eggman, he frequently talks back to him and often questions the logic behind his plans. In the Sonic the Hedgehog comics, Eggman has even openly wonderred why he would program Orbot with such sass. Orbot reminds the doctor that he works at his best in a competitive environment and that Orbot's own laziness is to provide Eggman with a smug sense of superiority.
Orbot has so far appeared in the video games Sonic Unleashed, Sonic Colours and Sonic Lost World. He also appears in the Sonic the Hedgehog/Sonic Universe comic books and also the CGI animated series Sonic Boom.
- Orbot was never named on-screen in Sonic Unleashed, but fans called him "Ergo" due to his habit of saying ergo a lot whilst pointing out the errors in Eggman's plan.
