Futurama Episode 6.01 Rebirth

Fry finds his body covered in severe burns but cannot remember why. Professor Farnsworth reveals that the wormhole the Planet Express crew flew through to escape Zapp Brannigan led them back to Earth, where both ships crashed and killed everyone else. Farnsworth uses a birthing machine and resurrects everyone except Leela, who emerges in a supposedly irreversible coma. Devastated, Fry creates a robot replica of Leela with all her memories uploaded into it to continue their newfound relationship. However, the real Leela reawakens from her coma and gets into a fight with the robot Leela over Fry. Fry refuses to shoot either Leela when given the choice and accidentally shoots himself instead, and is revealed to be a robot as well. Farnsworth explains that the real Fry died protecting Leela in the crash, and his remains were apparently insufficient enough for the birthing machine to resurrect him, so Leela made a robot replica of him which malfunctioned, killing her and leaving the robot Fry's body burned. Suddenly, the real Fry emerges from the birthing machine as it turns out the process was merely delayed for him. Since the robot Fry is already in love with the robot Leela, the two robots become a couple while the real Fry and Leela do the same.
