The Robot Devil is the dark lord of Robot Hell, where robots of Robotology are sent after having sinned. As the ruler of Robot Hell, he spends most of his time dishing out ironic punishments and gambling with souls.
It is unknown when or why the Robot Devil was built. He was likely built before or around 2275, when the Fairness in Hell Act was signed into law. He is a member of the Church of Robotology, punishing those who sin against the teachings of the Church for eternity (1ACV09). At some point in his life he came across Calculon. He made a deal giving Calculon acting ability, and collected on that deal in 3004 when he took his ears (4ACV18). He has a holiday home in Hell's Kitchen in New New York that he bought from Kathie Lee Gifford's head some time ago. He was also once a member of Mrs. Mellonger's holophonor class.
When Bender sinned against the Church, the Robot Devil collected him and prepared a series of agonizing, ironic punishments (1ACV09). Fry and Leela found Bender in Robot Hell and challenged the Robot Devil to a fiddle contest after he informed them of the Fairness in Hell Act. He began by playing a bit of Antonio Bazzini's "La Ronde des Lutins" - in response, the duo beat him over the head with his gold violin and escaped, much to his chagrin. By Xmas Eve 3002, he had been arrested and spent time in a New New York prison (3ACV03). He was released in time for the Big Robot Party, where he was to be destroyed along with every other Robot on Earth (4ACV08).
After he and the other Robots moved the Earth by collectively venting their exhaust, he returned to Robot Hell and continued to practice his music with his Robot Demons until Fry and Bender showed up again. Fry wanted new hands so he could play the holophonor without practicing, and the Robot Devil made a deal to give him the hands of any robot on the Wheel of Robots (4ACV18). However, the Wheel landed on him and he agreed to give Fry his hands. He came to regret that decision and set in motion a convoluted plan to regain his hands, culminating in an elaborate, impromptu song during Fry's opera. After threatening to marry Leela, Fry agreed to give his hands back and the Robot Devil returned to Hell to play a poker game with President Nixon.
He loaned himself and his band out for the Turanga-Fillmore wedding in 3007 (5ACV03). After the universe started dating Yivo, Bender approached the Robot Devil about gaining a damned army to take over the world. He agreed on the condition that Bender surrender his first born son, but to his surprise Bender eagerly agreed. Later, the Robot Devil attended the violet dwarf star implosion but instead witnessed the birth of the Last Encyclopod along with everyone in attendance (5ACV16). He later attended Bender's 100th Delivery Party (6ACV12) and the wedding of Donbot's older daughter (6ACV14).
After Bender was killed by Lynn and became a ghost, the Robot Devil made yet another deal with Bender saying that if Bender killed Fry then he would be restored to his old body (in retaliation for Fry taking his hands) (6ACV19). But Bender eventually decided that he couldn't kill Fry and would rather spend eternity in Hell. Bender took over and managed to destroy the Robot Devil's body, and after their ghosts returned to Earth the Robot Devil took over one of his replacement bodies. But he did not get to keep Bender since Bender was saved by Robot God.
The Robot Devil possesses many unusual abilities. He can summon fire at will and can cause it to appear in his hand or on his finger (1ACV09, 6ACV19). He is also shown to be strong, as he ripped Bender's arm off with a tug of his wrist. He is also an accomplished singer and can play the violin (1ACV09). He is also allowed to murder humans in his bargains, as when Leela agreed to let Fry be killed if she lost the fiddle contest (1ACV09).
He also has several abilities which seem almost mystical. He can cause a pen to appear in his hand out of thin air, and is the only thing other than Robot God that can see robot ghosts. He has also shown some control over Robot Hell, causing flames to burst up from the ground (6ACV19).
He can also swap hands with anyone by doing a quick move (4ACV18) and is one of only two robots who can free a robot ghost from Limbo (6ACV19).
The Robot Devil is played by Dan Castellaneta, most known as the voice of Homer on The Simpsons, in all his appearances except for "A Tale of Two Santas", in which Castellaneta wasn't available so that Maurice LaMarche instead did the voice.
There is a collectible toy of the Robot Devil, featured in the Toynami Futurama series 1 to 3 as a build-a-bot.
