* In #37, Evolt tosses up Grease to the air and finishes with a standing roundhouse rider kick, just like [[Series/KamenRiderKabuto Kabuto's]] Rider Kick.

* A {{Mentor}}, whose actions started the events of the series, with a MysteriousWaif daughter with supernatural abilities and no memory that gave TheHero his TransformationTrinkets [[spoiler:only to betray them and is revealed to be the alter ego of a commander of the enemy faction]]. This description can fit both Soichi and [[spoiler:[[Series/KamenRiderWizard Sou Fueki]]]].

** Another allusion to ''Dragon Knight'' comes in the form of [[spoiler:Evolto himself, as he shares the same traits as Xaviax: they are both extraterrestrials who are {{Manipulative Bastard}}s, they both destroyed a planet before (Mars and Karsh, respectively), they are both [[MasterOfDisguise Masters of Disguise]], they both [[DemonicPossession have the ability to possess human hosts]], and they both have a Rider form, human form, and a monster form.]]

* [[spoiler:Evolto's possession of Sento]] turns his normally black hair to white, similar [[Series/KamenRiderGaim to Kouta]] [[spoiler:after absorbing the Golden Fruit]].
* In #37, Evolto tosses up Grease to the air and finishes with a standing roundhouse rider kick, just like [[Series/KamenRiderKabuto Kabuto's]] Rider Kick.

* It's a little known fact that the producers of ''Series/KamenRiderW'' wanted the Rider's most-used form to have Heat, and the red half, front and center because of LawOfChromaticSuperiority. With Build, they finally have their wish.

* Both Night Rogue and Blood Stalk are inspired by the 2/3's of the classic "bat, snake, spider" trio of monsters from the original ''Series/KamenRider''. Though unlike most, they're major villains rather than MonstersOfTheWeek. [[spoiler: ''New World: Cross-Z'' gives us Kilbus, who's rider form is a spider, completing the trio.]]

** As mentioned in the Trivia page, Sawa shared surname with another [[spoiler: backstabbing]] [[Series/KamenRiderWizard character]].

** [=SmartphoneWolf=] is almost exactly what you'd expect for [[Series/KamenRiderFaiz Faiz, save for smartphones being fairly recent tech... except that it WAS Smart Brain making the gear.]]

*** [[spoiler: Similarly, his super forms, [[DepartmentOfRedundancyDepartment Rabbit-Rabbit and Tank-Tank,]] are essentially a one-man version of Double's own Cyclone Cyclone and Joker Joker [[Series/KamenRiderDecade Final Attack Ride,]] and gives him access to a weapon functionally similar to the Prism Bicker.]]

** [[spoiler: His dragon motif also brings to mind [[Series/KamenRiderAgito other]] [[Series/KamenRiderDenO riders]] [[Series/KamenRiderWizard themed]] around dragons, except unlike Agito, Den-O Gun Form, or Wizard, he's the first secondary to explicitly have this theme[[note]]although if one counts Tertiary Riders, [[Series/KamenRiderGaim Ryugen]] has him beat[[/note]].]]
** And adding to [[Series/KamenRiderRyuki Ryuki's]] homage, [[spoiler: Kamen Rider Cross-Z's]] debut episode had him fight a bat-themed Rider with one of the rider's reasons for becoming a Rider involves his girlfriend's death.

** The same episode references the same series in [[spoiler: its title. “The False Kamen Rider” refers not to the hero’s battle with a Rider-like foe, but to the question of whether he’s really a hero or not after the way his entire journey has been part of the villains’ manipulation. He decides that no, it wasn’t all a lie, because his devotion to protecting people is real even if his mentor’s was not, and he will continue]]. Meanwhile, Black RX has an episode called “False Rider’s Last Days.” Not too long before, Shadow Moon had come BackFromTheDead, so has he come back again? Again, the ‘False Rider’ isn’t the Rider-like bad guy. Kotaro’s own doubts, and him finally getting over them - making it his last days as a false Rider in his own mind - were the focus of the episode.

** Speaking of ''Dragon Knight'', the transformation sequence for [[spoiler: Evol Dragon]] uses the sphere with flipping symmetrical rings (in this case, gears) from that show.
** Another allusion to ''Dragon Knight'' comes in the form of [[spoiler:Evolt himself, as he shares the same traits as Xaviax: they are both extraterrestrials who are {{Manipulative Bastard}}s, they both destroyed a planet before (Mars and Karsh, respectively), they are both [[MasterOfDisguise Masters of Disguise]], they both [[DemonicPossession have the ability to possess human hosts]], and they both have a Rider form, human form, and a monster form.]]
* The big reveals of #13 and #14 combine with HarsherInHindsight to make [[spoiler: Sento’s own name this. A while back, it was a cute absent-minded-professor moment when it turns out the name Soichi gave amnesiac Sento just means “Rabbit Tank.” Now we realize that, in naming him after his first Best Match, it’s exactly what we saw not too long ago with Masamune Dan calling everyone by their Gashats’ names: the ManipulativeBastard villain calls the hero by his TransformationTrinket’s name because he sees him as just another product of his organization to be used for his plan.]]

* Rather poetic that the series premise takes place in a future divided Japan when a [[Series/KamenRiderGhost previous rider]] gained the powers of historical figures who reunited Japan in an era where the throne of Japan is about to be passed on to boot.

* The fact that the Sclash Driver can turn someone aggressive for every use brings to mind the Delta Driver from ''Series/KamenRiderFaiz''.

** And a final nod to his past role, [[spoiler: he uses the Blizzard Knuckle to get his last form, similar to the IXA Knuckle. Moreover, it's also a DeadlyUpgrade like IXA and Dark Kiva. He even ends up [[DyingInYourArmsTonight dying in the arms]] of a woman he loved after his last battle.]]

* [[spoiler:Evolto's possession of Sento]] turns his normally black hair to white, similar [[Series/KamenRiderGaim to Kouta]] [[spoiler: after absorbing the Golden Fruit]].
* In episode 37, Evolto tosses up Grease to the air and finishes with a standing roundhouse rider kick, just like [[Series/KamenRiderKabuto Kabuto's]] Rider Kick.
* In episode 41, the monster from the very first episode becomes an important plot point, not unlike in [[Series/KamenRiderGaim another series]] where this happens, but earlier.

* A rehash of her actress' role in ''[[Series/KamenRiderW W Returns: Accel]]'' and ''[[Trivia/KamenRiderGhost Ghost]]'' this time with Sawa [[spoiler:leading a double life]].

* [[spoiler:Evolt's possession of Sento]] turns his normally black hair to white, similar [[Series/KamenRiderGaim to Kouta]] [[spoiler: after absorbing the Golden Fruit]].
* In episode 37, Evolt tosses up Grease to the air and finishes with a standing roundhouse rider kick, just like [[Series/KamenRiderKabuto Kabuto's]] rider kick.

** Blood's design, on the other hand, is a fusion-like upgrade of existing rider's forms - much like [[Series/KamenRiderGaim Kamen Rider Saver]].

* Kamen Rider Grease being assisted by the Hokuto Three Crows can be a throwback to how [[Series/KamenRiderKiva Otoya and Wataru are assisted by the Arms Monsters]]. However, the Crows show UndyingLoyalty while the Arms Monsters are, at best, VitriolicBestBuds with Otoya. Grease also happens to portrayed by Otoya's actor.

* Sento isn't the first Kamen Rider lead to have [[Series/KamenRiderAgito lost his memories]]. Not [[Series/KamenRiderDecade the second either]]. Not even [[Series/KamenRiderDouble the third]] (or at least half of the pair). And like the latter two, [[spoiler:he turns out to be a former top-ranking member of the evil faction]]. Both Philip/[[spoiler:Raito Sonozaki]] and Sento/[[spoiler:Takumi Katsuragi]] were [[spoiler:token good teammates to their faction and were vital to the creation of their shows' transformation trinkets]].

* In #15, Sento and Ryuga come to a familiar place... it's [[Series/KamenRiderExAid Seito University Hospital!]] Even better, in there Sento cosplaying as Hiiro and Ryuga as... you guessed it, Poppy. They are not a year behind, just investigating a possible clue.

** Kazumi's dog tag number: 907101080, another reference to Kiva[[note]]9-0-7-1-0-10-8 = Ku-Re-Na-I-O-To-Ya[[/note]].

* The Cross-Z Dragon is an animal-shaped RobotBuddy [[Series/KamenRiderHibiki that sounds like a mishmash of musical instruments.]] [[Series/ZyudenSentaiKyoryuger Including a samba whistle.]]

* Kamen Rider Grease being assisted by the Hokuto Three Crows can be a throwback to how [[Series/KamenRiderKiva Otoya and Wataru are assisted by the Arms Monsters]]. However, the Crows show UndyingLoyalty while the Arms Monsters are, at best, VitriolicBestBuds with Otoya.

* In #15, Sento and Ryuga come to a familiar place... it's [[Series/KamenRiderExAid Seito University Hospital!]] Even better, in there Sento cosplaying as Emu and Ryuga as... you guess it, Poppy. They are not a year behind, just investigating a possible clue.

* Both Night Rogue and Blood Stalk are inspired by the 2/3's of the classic "bat, snake, spider" trio of monsters from the original ''Series/KamenRider''. Though unlike most, they're major villains rather than MonstersOfTheWeek.

* The helmet interface is shared with Birth and Proto Birth from ''Series/KamenRiderOOO''.

** And a final nod to his past role, [[spoiler: he uses the Blizzard Knuckle to get his last form, similar to the IXA Knuckle. Moreover, it's also a DeadlyUpgrade like IXA and Dark Kiva.]]
