* [[Manga/CorpsePrincess Monk slaying zombies]] you say?

* In #31, as Ex-Aid and Genm deliver a NoHoldsBarredBeatdown on Pallad with their weapons, they swap places with a move similar to the Total Elimination/[[Wrestling/TheAscension Fall of Man]] where Ex-Aid does a leg sweep and Genm does a spin kick from mid-air.

-->'''Emu''': Once I beat you, Kamen Rider Chronicle will be over.

* [[Manga/DeathNote 2 geniuses known as M and N having a one-sided rivalry since they were young, both geniuses' names are related to their alphabets]], coinciding with an [[Film/DeathNote2017 american live-action adaptation]] in the same year 2017.

* Kamen Rider Cronus' powers are similar to [[Manga/JojosBizarreAdventureStardustCrusaders DIO]]'s stand, The World. He can [[TimeStandsStill "pause" the universe]] and conveniently attack his opponents while they are completely immobile.

** Speaking of Sentai, Dan Masamune [[spoiler: initially]] appearing to be a BenevolentBoss and overall, LighterAndSofter in comparison to Kuroto, [[spoiler: only to be revealed that not only is it all an act, he's as bad, if not worse than, his son]] brings to mind [[Series/ChoujuuSentaiLiveman Great Professor Bias]][[note]]although in Bias's case, he appeared LighterAndSofter in comparison to the previous Sentai big bads as opposed to another ''Liveman'' villan[[/note]].

* It's been noted that [[spoiler: Masamune]] as Cronus bears similiarities to the Greek God of the same name as well as powers related to the Greek God Chronos.
