- Canon Discontinuity: How Toei has treated this series and Tetsuwan Tantei Robotack as of late - while the series were listed in one of the Super Hero Taihen specials, said list also included Moerro!! Robocon, which is definitely NOT a Metal Heroes series, so it was likely referring to series that had come out during the period of time that Kamen Rider was on hiatusnote ; later, Super Hero Taisen Z showed a list of the Metal Heroes series, with this series and Robotack both being absent from said list; doubles as Missing Episode, since these 2 are the only series that have not received DVD re-releases.
- Keep Circulating the Tapes: As noted above, this is one of the two Metal Hero series that Toei has not released on DVD, although they did eventually upload entire series onto their Youtube channel in late 2017.
- Missing Episode: The series itself could be considered one for the entire Metal Heroes franchise, as not only is it the only one to not be released on DVD in any form save for a few specials, but Toei themselves seem to pretend that it never happened.
- The Wiki Rule: Covered as part of the Metal Hero Wiki and as an individual series on the Kabutack Wiki.
