** The Roidmude executives aid the Riders in the fight against Megahex because of its callous use of Roidmude technology, as well as because they disagree with the idea of an AssimilationPlot, believing in the [[EvilVsOblivion importance of individuality]].

* ShoutOut: The final battle on Planet Megahex manages to combine DownLADrain with the trench run from ''Film/StarWars!''

* BodySurf: [[spoiler:Zoruko manages to survive his defeat by hijacking a viral core. That said, he now considers Shinnosuke his WorthyOpponent and thus is less likely to cause trouble.]]

* DecoyProtagonist[=/=]SupportingProtagonist: Kouta is this in the Gaim part of the movie. [[spoiler: Kouta gets killed by Megahex at the start]] in which case the story follows Micchy and Takatora as they try and stop Megahex. [[spoiler: Kouta does come back at the end to help the two brothers]], but only after the two finally settle their own personal demons.

** Mashin Chaser helps Drive against Lupin because [[spoiler:Lupin is a human using a Roidmude body.]]
** The Roidmude executives aid the Riders in the fight against Megahex because of its callous use of Roidmude technology, as well as because they disagree with the idea of an AssimilationPlot, believing in the importance of individuality.

* {{Expy}}: Megahex is basically [[Anime/DragonballZ the Big Gete Star.]] [[spoiler:Including the ability to make numerous clones of himself until finally having his core destroyed.]]
** In the context of Gaim's story, Megahex is a robotic {{Expy}} of [[spoiler:DJ Sagara, as both are the avatars for a massive, powerful, extraterrestrial collective that seeks evolution]].
* FreezeFrameBonus: During the fight scene between Chase and some numberless Roidmudes, one can see Fuuto Tower in the background.

* {{Foreshadowing}}: Drive's reaction to Gaim calling himself a "Space God". Shinnosuke is shown to have trouble wrapping his mind around things that don't make sense to him, as [[Recap/ShurikenSentaiNinningerVsKamenRiderDrive seen later on down the road.]]

* FusionDance: [[spoiler: Megahex combines himself with the [=CyberRoid ZZZ=], to become the movie's BigBad, Megahex ZZZ.]]

* {{Mooks}}: Megahex creates his own army of Mecha Inves and Mecha Roidmudes, based on their pre-MonsterOfTheWeek forms respectively, Elementary Inves and Low-Class Roidmudes. Lupin also creates a trio of his own Roidmudes, one for each animal type, via his Lupin Gunner.
* NonSerialMovie: Averted. Gaim's story is the GrandFinale for his series, while Drive's portion is referenced in the show proper. Adding the fact that Type Technic appears in the movie enables us to pinpoint the exact placement is the show's timeline - between episodes [[Recap/KamenRiderDriveEp9HowCanIGetUsedToTheCoolBody 9]] and [[Recap/KamenRiderDriveEp10WhatHappenedInTheBeltsPast 10]].

* NiceJobFixingItVillain: Megahex's actions allows Takatora to regain both of his Armored Rider Zangetsu powers. [[spoiler:As Zangetsu, he duels and wins against Cyborg!Ryouma while Micchy saves Mai. Then as Zangetsu Shin, he manages to steal the Kiwami Lockseed Megahex had on him which allows Kouta to return.]]

** During their fight at the beginning, Kouta seemingly destroys Megahex, only for him to step out of a portal behind Kouta unharmed. [[spoiler:Justified, as Kouta ''did'' destroy Megahex, just there happens to be ''multiple'' avatars. Megahex's core has to be destroyed to actually put him down.]]

** Megahex is absolutely this from the perspective of Drive. He literally shows up out of nowhere, [[spoiler:merges with the burnt-out Roidmude body of Cyberoid ZZZ]], and flies off. He has no other connection to any of the backstory and lore of ''Drive''.

* PowerCopying: As is tradition for recent crossovers. Drive and Gaim get to exchange their forms, with Drive assuming Type Fruit to use Orange Arms' powers, [[CoolSword Daidaimaru]] and [[SwissArmyWeapon Musou Saber]], while Gaim gets to use Drive Arms, getting access to Type Speed's abilities as well as the [[CoolSword Handle Sword]]. As an added bonus, [[CoolCar Tridoron]] turns into A SPACE CAR.

** [[spoiler:Megahex's core back on his planet of origin is this for him. So long as it's still active, destroying his bodies is pointless as he will make more copies.]]

* ThirdPersonPerson: Megahex tends to refer to himself in the third person.

* WellIntentionedExtremist: Megahex sincerely seems to believe that his AssimilationPlot is the ultimate form of evolution, and thus is making beings become the UltimateLifeform by absorbing them.

* BrokenStreak: This is the first Movie War ever to not feature Kamen Rider Double in any capacity, though one element of Double's series does briefly cameo in this[[note]]When Chaser is fighting the numberless Roidmudes made by Lupin, Fūto Tower can be faintly spotted in the background[[/note]].

* DecoyProtagonist[=/=]SupportingProtagonist: Kouta is this in the Gaim part of the movie. [[spoiler: Kouta gets killed by Megahex at the start]] in which case the story follows Micchy and Takatora as they try and stop Megahex. [[spoiler: Kouta does come back at the end to help the two brothers]], but only after the two have finally settle their own personal demons.

* {{Foreshadowing}}: Drive's reaction to Gaim calling himself a "Space God". Shinnosuke is shown to have trouble wrapping his mind around things that don't make sense to him, as [[Recap/ShurikenSentaiNinningerVsKamenRiderDrive see later on down the road.]]

Gaim's section, titled '''"Charge into the Last Stage!"''', set after the end of his series, involves a new, unknown metallic life form known as Megahex. It crashed on Kouta & Mai's peaceful planet with the aim of destroying both it and Gaim. Kouta fought it at his strongest... but was still defeated?! Meanwhile in the now peaceful Zawame City, the remaining Kamen Riders, with restored powers, must take on a seemingly revived Ryoma Sengoku.

In Drive's section, titled '''"The Challenge from Lupin"''', the Special Division must track down Zoruko Tojo, aka the Ultimate Thief Lupin. It won't be so easy, as not only he somehow possesses the power to cause [[TimeStandsStill Slowdowns]], he is also able to transform like Shinnosuke can, turning into the villainous Kamen Rider Lupin!. His goal - to steal the ''title of Kamen Rider itself''. The mysteries pile up - Why does Tojo desire the title? What is [=CyberRoid ZZZ=]? And how does Mr. Belt fit into all this?

* OutsideContextVillain: Megahex is an out-of-context villain who seemingly appears just to wreck Kouta's planet. [[spoiler: Subverted however, as Cyborg!Ryoma later exposes that Megahex was how one planet managed to solve the Helheim Forest's problem.]]
