The Robotic Fizzarolli, also known as Robo Fizz, is a line of robotic doubles of the popular imp jester Fizzarolli, manufactured in Asmodeus' factory. Several models of the animatronic exist in a wide variety of colors and are designed for various purposes, primarily entertainment. They are robotic imitations of Fizzarolli, created to replicate his appearance, personality, and entertaining performances.

The original Robo Fizz performed regularly at Loo Loo Land alongside his band, FizzaRolli 'n Friends, entertaining guests with his comedic performances, songs, and exaggerated showmanship. Like the other models, he possesses a mechanical body and robotic features designed to imitate the real Fizzarolli.

Robo Fizz is a supporting antagonist in Helluva Boss, making his debut in the episode "Loo Loo Land". During the episode, he encounters Blitzo and Moxxie while performing at the amusement park. He later reappears in "Return to Loo Loo Land" in a decrepit condition, alongside the newest model, which had replaced him at the park.

Following these events, Blitzo takes the head of the original Robo Fizz and revives him, keeping him in his office at the I.M.P. headquarters to torture him.

As of "The Full Moon", the Robo Fizz models have been put up for a blowout sale by Mammon, who no longer wants them following Fizzarolli's departure from his entertainment business. Despite being manufactured as replacements and imitations of Fizzarolli, the robotic doubles remain separate from the original imp himself.
