"Mighty Jack" is a 1968 sci-fi/spy thriller toku series inspired by the works of Gerry and Sylvia Anderson, and was produced by Tsuburaya Productions following the completion of Ultraseven (1967). Focusing on human antagonists instead of monsters and aliens, Eiji Tsuburaya considered it his magnum opus. Unfortunately, the show was unsuccessful; consequently, the show's second season, "Fight! Mighty Jack" was retooled to add monsters and aliens back in. While I have seen uploads of raws for "Fight!" ([here](https://nyaa.iss.one/view/812367) and [here](https://nyaa.iss.one/view/1266195)), I have not seen any for the original series. As such, I have taken the acquiring and uploading the show myself. I hope people enjoy! It'd be nice to see more of the non-kaiju TsuPro output (alongside some of the more niche Ultra Series spinoffs) get translated.
