- ―Beezelbot, complaining to Bender
Beezelbot, commonly referred to as the Robot Devil, is one of the recurring antagonists in Futurama. He seems to resemble the Devil of many Earth religions. He lives in Robot Hell along with many other sinners. He is talented at playing the fiddle, therefore, he owns a golden one. He lives in a New Jersey amusement park, apparently closed due to the salmonella produced by the flume ride. The Fun House has the symbol of Bender's new religion, so Fry pushed it, leading to a slide to Robot Hell. 
When Bender broke his promise to Robotology (a robot religion) under the influence of Fry and Leela, the Robot Devil kidnapped him and took him to Robot Hell. However, Fry and Leela were able to save him if they bested him in a fiddle contest. However, neither Fry nor Leela could play the fiddle, but Beezelbot's was made of solid gold. Leela hit him over the head with it, and they made a successful escape.
Beezelbot swapped hands with Fry so that Fry could become better at playing the holophoner. He also seems to be able to summon flames, and has a bit of talent with illusions demonstrated at the opera with Nixon and him supposedly engulfed in the flames. He is a bit into the theatrical, bursting into song when possible, and has a bit of talent for it judging from his brief performance at the opera. 
As head of the League of Robots, Bender sold the soul of his firstborn to Beezelbot in exchange for an Army of the Damned, something Beezelbot claimed was cold-blooded even by "his" standards.(Arguments pursue whether or not that was his actual son, due his surprise and confusion in "The Bots and the Bee's" because of him not knowing the facts of life.) His hands are very well coordinated. He can swap his hands with any human very fast and the human doesn't feel any pain. His arms, legs, upper, and lower torso resemble bender's body parts very much though his fingers are pointed, and his feet are two-toed (much like the cloven hooves of the Christian devil) rather than Bender's semi-sphere feet. He also has a bit of flamboyancy in his speech and movements, easily angered by being mocked. He is a bit hypocritical, once confronting Fry about his opera characters "lacking subtlety" and "announcing how they feel" by saying "That makes me feel angry!" Beezelbot has backup bodies in case he dies and goes to Robot Hell.
Beezelbot has a small musical band who play the Robot Hell Theme Song. The group plays at the wedding of Lars and Leela, and apparently seem to be able to appear whenever Beezelbot spontaneously breaks into song.
