* NamesTheSame: Episode 53 centers around a mad scientist named Dr. Shinigami, not to be confused with the one from ''Series/KamenRider''.

* TheOtherDarrin
** The actor for the Black Cross Fuhrer was changed from Mitsuo Ando (best known for his role as Professor Gill from ''Series/{{Kikaider}}'') to Nobuo Yana from Episode 54 and onward. Incidentally, Nobuo Yana guest-starred in Episode 53 as Dr. Shinigami (not the one from ''Series/KamenRider'').
** General Magman was originally voiced by Eisuke Yoda for his first three episodes (42-44), before he was replaced by Creator/ShozoIizuka (also the voice of General Temjin and Grand General Golden Mask).
* PropRecycling: Many of the Masked Monsters wore similar body suits such as ''Yakyū Kamen'' (Baseball Mask) and ''Terebi Kamen'' (TV Mask). The most notable is ''Tiger Kamen'' (Tiger Mask), who is a recycled version of ''Kōtetsutora Kamen'' (Steel Tiger Mask).
* TypeCasting: After Daita's actor was constantly typecast as Kirenger and got into financial problems, he commited suicide (although Tsuyoshi's actor tried to talk him out of it).
