Hermes does a performance review of the Planet Express staff, vowing to fire the most inefficient employee. This turns out to be himself, and he's replaced by a bureaucratic robot. In order to reclaim his job and be more efficient, he starts augmenting himself with robotic parts. It starts with a harpoon in his chest, before he eventually is almost entirely robotic. He eventually wants to get a robot brain installed by Professor Farnsworth, who digs up the brain of the psychopathic stabbing robot Roberto, who was killed after he threatened to steal LaBarbara's skin.

Hermes eventually gets his robot brain, though his human brain is put back in his old body that Zoidberg kept and was using as a ventriloquist's dummy. Roberto is felled when he tries to eat Hermes' skin, which melts him when it proves to be too spicy thanks to years of LaBarbara's Jamaican cooking.
