Call-Back: Yamato is aware who Marvelous is due to their teams meeting in episodes 28 and 29 of Zyuohger.
Decoy Protagonist: Among the first characters to get a focus is Keiichiro. With the way he is set up with Yamato, where the latter wonders if he'll be on his team, it seems likely he'd be a member of the main cast. Instead, Yamato goes on Team Oddball and fights Keiichiro, ultimately winning and eliminating Keiichiro's team from the bracket.
Early-Bird Cameo: Towa / Ryusoul Green and Banba / Ryusoul Black make their very first appearance at the end of this episode.
Fake Shemp: Besides Marvelous and Luka, none of the other Gokaiger characters reprised their roles, so during their brief scene at the beginning of this episode they are played by recycled audio clips from their home series.
Almost all the Sentai heroes summoned, totaling well over a hundred, can be seen gathered at the planet Nemesis. Beyond the relative handful of those whose actors returned, the rest are seen only from the back, portrayed by extras.
