Sevenger Fight (セブンガーファイト Sebungā Faito) is an Ultra Fight-inspired miniseries set in-between episodes of Ultraman Z, which this series acts as a spin-off to. Episodes 1 to 7 of the series were released exclusively through the TSUBURAYA IMAGINATION streaming service, with episodes 8 to 10 being found in the Ultraman Z Super Complete Works STORAGE BOX DVD and Blu-ray set. As opposed to other recent supplementary shows in the Ultraman Series, Sevenger Fight takes most of its influence and aesthetics from the original Ultra Fight and its direct-to-video 'follow-up', Ultra Super Fight.
