Fritz Huhnmörder, best known simply as the Mad Scientist, Robot Man and Cyborg Scientist, is the central antagonist as well as an anti-hero of Robot Chicken.
In the series opening credits for the first five seasons, the Mad Scientist finds a dead chicken on the road and revives it as the titular Robot Chicken to subject the bionic poultry to watch various TV monitors broadcasting the show's sketches. Some time equivalent to five television seasons later, during the 100th episode, the Chicken escapes with the Mad Scientist capturing his former captive's girlfriend, Cluckerella, and subjecting her to watch countless television shows in his stead. When the Chicken confronts his captor, the Mad Scientist is shown to be an incredible fighter before he accidentally gets his wrist caught in the viewing chair's arm locks, and meets his initial end when the Robot Chicken pushes over the TV monitors, crushing him to death. As revealed in the new opening credits, the Chicken revives the Mad Scientist as a cyborg while subjecting him to watch the re-stacked TV monitors in an ironic twist.
In the 139th episode, Chipotle Miserables, the Mad Scientist's crazed son steals his father's one remaining organic eye to unlock a door guarded by an optical scanner. He then uses parts inside to create cybernetic creatures of his own, including Cyborg Raccoon, Robot White-Tailed Deer, Robot Homeless Person, and Dark Meat (an evil version of the Robot Chicken). He then kidnaps all five living presidents (accurate at the initial episode broadcast date) and forces them to watch the show's sketches on TV monitors, or else they will be forced into a "Human Centipede"-esque torture method. Both the Robot Chicken and a cybernetically-enhanced Mad Scientist arrive to defeat the latter's son and his cyborg minions, and he is forced to watch the sketches in the torture chamber as punishment. The Robot Chicken then activates his mechanical wings and flies off.
A descendant of the Mad Scientist appears in the intros for Seasons 8 and 9, where his drones dig up a frozen Robot Chicken in the future. The Chicken is freed from the ice, only to be forced to watch more sketches.
The Mad Scientist and the Chicken work together to rebuild and revive the Nerd as a cyborg in season 10 and is forced to watch sketches. In the season 10 finale, he takes him in a crate while the TV monitors display static.
