In February 2019, it was announced that Marvel Television was developing an adult animated television series based on M.O.D.O.K., with a series order at Hulu, along with ones based on Hit-Monkey, Tigra and Dazzler, and Howard the Duck, that were intended to lead up to a crossover special titled The Offenders. In December 2019, Marvel Television was folded into Marvel Studios, which carried subsequent oversight of the series. The following month, Marvel decided not to move forward with Howard the Duck, Tigra & Dazzler, and The Offenders, with M.O.D.O.K. (2021) and Hit Monkey continuing as planned.
Hit Monkey, the character, was created as a parody of Agent 47, the lead character in the Hitman video games
This series takes place in the Earth-1226 version of the Marvel Universe, together with M.O.D.O.K. (2021).
Hit Monkey is based on the comic book character of the same name.
