Despite this, the inhabitants of both worlds, humans and Kikainoids, quickly got along and live peacefully together.

Although Zenkaiger is open to the idea of featuring past heroes in certain episodes, Shirakura mentioned that it will not be done in a similar way to Kaizoku Sentai Gokaiger. The four Kikainoids were based on the non-human members of Uchu Sentai Kyuranger. The reason why Zenkaizer was chosen as the leader despite being colored white instead of red is to ensure that he would stand out in future crossovers when grouped alongside other Red Rangers. Īccording to producer Shin-ichiro Shirakura, the show's diversity in its titular members, featuring a human and four Kikainoids, is due to the Super Sentai series' recurring themes of diversity in its group of protagonists while maintaining strong characters. The trademark for the series was filed by Toei Company on September 8, 2020.
