Robot Chicken

Robot Chicken  is the main protagonist of  Robot Chicken, who is featured in the opening sequences. Chicken led a boring life of clucking, pecking, and scratching on Old Man McLauchlin's farm until his untimely death on Highway 9W. Resurrected by a Mad Scientist as a cyborg, Chicken now spends every living moment sampling brain-numbing television and wishing for death, much like the average television viewer for time equivalent to five seasons before he escaped. However, while starting fresh, Chicken learned that the Mad Scientist captured his girlfriend and fights various characters to save his love before managing to kill his tormentor. However, in an ironic reversal of roles, Chicken turns the Mad Scientist into a cyborg and subjects him to the same mind-numbing torture he was subjected to. Despite saving his girlfriend, it is later revealed that she end up break-up with him, leaving him depressed. He is eventually forced to team up with his creator/nemesis when the Mad Scientist's Son kidnaps President Barack Obama and the former Presidents. Robot Chicken faces off against his evil counterpart Dark Meat and the son's other non-chicken cyborgs Cyborg Raccoon, Robot White-tailed Deer, and RoboHobo. Robot Chicken manages to defeat the son's cyborgs while the Mad Scientist deals with his son. After saving the presidents, the Mad Scientist punishes his son by forcing him to endure the same brain-numbing television that he and Robot Chicken were subjected to.

He  is one of the troublemakers but was saved by The Code Lyoko Warriors due to his adoptive parents ground him.
