Drive's name has a double meaning. While it plays into the car motif, the title Rider had ALSO lost his drive for his work after his partner was crippled. When he becomes Drive again, he's regaining his lost drive.
"All we need is Drive" can either mean "All we need is our hero, Drive" or "All we need is our drive".
Every human affected by the Density Shift is still able to think in "real time", despite everything slowing down. But keep in mind that Roidmudes' bodies are covered in a material that is similar to the cerebral cortex, with hides and protects them from the effects of Slowdown particles. That means that a human brain offers natural protection against Slowdowns.
This is supported in episode 7, when a Roidmude attaches a part of it's body to a man in order to make him immune to Slowdown.
The Roidmudes' using Proto-Drive's design to create Mashin Chaser makes a lot of sense on several fronts. Having a powerful warrior that can beat any rebellious member is a no-brainer, but remember that Proto-Drive's weakness was being unable to permanently kill Roidmudes. That flaw is particularly useful for the villains, as with this they have a handy way to deal with any unruly Roidmude by "reseting" them without needing to imprison or kill them. Add the fact that it's based on the enemy that stopped them all, it makes calling Mashin Chaser a Grim Reaper have that much more power to it.
The facts that Chase is known as the Grim Reaper to Roidmudes and has a battle form similar to their enemy the Kamen Rider, when combined with the fact that Proto-Drive was also voiced by Chase's Live Actor in Episode 0, had also foreshadowed the fact that Chase WAS Proto-Drive.
It makes sense that we never see Drive use the Deco Traveller for a tire change. After all, the one time we do see it used (when Drive uses it to overload Mashin Chaser's break gunner), it disorients Mashin Chaser - if Drive used it, it would likely have the same effect on Drive himself.
Mashin Chaser's Transformation Trinket is called the Break Gunner. This has three separate meanings:
Braking means slowing down, as in the Slowdown effect created by the Roidmudes.
Braking would also contrast with Drive; driving implies movement, while braking implies standing still.
"Break" as in breaking things apart, playing on the "Brake" / "Break" homophone.
Why is Iron Roidmude called such, even if there isn't even a speck of metal on him? Consider that 1) he's shown to be a Bad Boss and 2) he fights with his fists. Conclusion - he has an iron fist.
The Roidmudes evolution mirrors human growth.
Infant (Core) - Roidmudes who have had their personalities reset and are therefore blank slates.
Child (Low-Class) - The Roidmude is starting to develop a personality. They have a few unique traits of their own but whoever has the greatest influence on them creates their dominant personality traits. Roidmude 084, for example, had a personality similar to the Paint Roidmude but was timid whereas the Paint Roidmude was confident.
Teen (Advanced) - The Roidmude has developed a unique personality but is still growing. They become much more selfish and reckless, believing themselves to be invincible thanks to their new powers. They act like older siblings, teachers, or friends to their lesser-evolved comrades, causing them to develop personality traits similar to their own.
Adult (Fully-Evolved) - Roidmudes like Heart and Brain that have evolved to the point that their personalities are fully-developed. They no longer have the recklessness of their youth and have enough self-control to not satisfy every single one of their desires.
Drive being the only Heisei Rider other than Fourze and Double to be called a Kamen Rider in-universe makes more sense when you look at the path production was heading; Drive is number 16. Remember that in the Taisen, the two Rider sides (Showa vs Heisei Lead Riders) were equal with fifteen on each side (Showa was Ichigo to J, and Hesei was Kuuga to Gaim); Drive is the symbol that the Heisei Era has now both figuratively and literally surpassed the Showa Era, in both number and years of the era-shows running.
A heart can only take so much before it fails, and goes into cardiac arrest. What was the method that Drive tried to kill Heart again?
For the Advanced Roidmudes, there is a connection between their current motif and their previous Low-Class forms.
Cobra-Type
Freeze: Certain cobras' venom can affect memory and latent learning. Some can disguise themselves as harmless specimens as well. Just like the Secretary of Defense...
Medic: Antidotes are used to stop venomous bites from creatures like cobras, like how Medic can prevent Drive's finishers from killing other Roidmudes. Worth noting is that cobra venom can be used to develop its own antivenom, which is why you should catch the snake responsible for the snakebite and show it to the doctor too. It may also relate to the Caduceus, the symbol of medicine, with is represented by two snakes. And one of the oldest ones in the book (literally): Medic has been manipulating Heart and Chase, like the serpent tempted Eve to sin.
Iron: Had a very long neck, resembling that of a snake. He also left his victims in a coma, with is what often happens after a person is bitten by a snake.
Crush: His huge shoulder pads may be a reference to a cobra's head, splaying out their hood to make themselves look bigger than they really are.
Judge: Serpents in some circles have been portrayed as symbols of vengeance and vindication, not to mention the cables Judge can make from his arms can be liken to a striking snake. Also, cobra bites are infamously lethal and are still widely considered a death sentence.
Open: Cobras can attack or come out of the open. As for his key, there is an American key management service company known as "Cobra Key Systems".
Cook: Snake meat, like king cobra meat, have been used as ingredients for some exotic dishes. His sauce, however, is a reference to the inclusion of an AC Cobra in the 2015 Honfleur Classic Rally Tour.
Spider-Type
Heart: What do hearts and spiders have in common? Strings.
Paint: Both Spiders and Paint himself can shoot a compound from a bodily orifice that can be used to make something. Also, Paint liking Kiriko's look of terror when he attacked her echoes the fact that quite a lot of people have a fear of spiders. His methods may also refer to how spiders hunt; by capturing their prey in a trap.
Volt: Spider threads could be considered a counterpart to wires found in electronics. It should also be noted that even his Advanced form still bears a strong resemblance to an arachnid.
Voice: Lures his victims in with his hypnotic... well, you know. There is a species of spider known as the bolas spider that lure in their prey, mainly moths, with scented bolas.
Imitation Drive: Based on a species of spiders that disguise themselves as ants, to the point of being able to replicate their traits.
Shocker Buruburu: He collects fear from people, and one of the most common fears known to mankind is arachnophobia, the fear of spiders.
Seeker: Has what appears multiple eyes on its head, like the eight eyes on an actual spider. Plus some people have quite an averse reaction to spiders and will violently try to squash them on sight, which could be an analogue to Seeker's ability to induce violent madness in people, and finally Seeker resembles a wizard in design, and several fantasy series have included things like giant spiders and other kinds of spider-based imagery as part of the story.
Tornado: Tornados, as you know, spin in a spiral pattern. Orb-weaver spiders are known to have spiral-like designs in their webbings.
Paradox: A time paradox can be simply described as a knot in the timeline. Timelines can also be alternatively described as a web of events.
Bat-Type
Brain: Bats have one of the most uniquely developed brains in the animal kingdom.
Scooper: He got his Advanced form through mind controlling and feeding off a human being like a vampire and bats use echolocation to get a good look at their surroundings like how cameras are used to get a wide look at the surrounding area.
Gunman: Could be a reference to the Bat Orphnoch from 555, who also had a prominent cowboy motif.
072: He mimicked Saijou Kyu, who's something of a Hikikomori. 'Bat' in Japanese is 'komori'.
Shoot: Could be a reference to the frankly harebrained idea of using bats as bombers back in World War II, as well as the fact the shoulder-mounted warheads he shoots avoid obstacles via echolocation.
Sword: His arm blades could be stimulating a bat's wings. His arc also introduces the Neo-Viral Cores and Fusion Evolution, which can be seen as a inversion of the classic Demonic Possession trope (where here, the human is in control of a Roidmude body), as bats are often attributed to demons in the West.
Thief: As in "thieving bats", the practice where bats mess up another bat's echolocation to get at some grub.
Considering the creator of the Mach Driver Honoh indeed knows who Krim is, being his mentor and all, it would make sense they would try to find a way to combine their two Riders' powers in some way, which results in the Ride Crosser.
Kamen Rider Lupin has a lot of similarities to Chase, including their weapons, that both of their Roidmude forms are repaints of one another. This makes sense with The Reveal that Chase was originally Proto-Drive and Cyberoid ZZZ was created by Krim. If Krim also made Chase, this means the two are equal to twin brothers.
Kamen Rider Mach's color scheme is the same of Drive's. However, while Drive and Trideron's primary colors are red with white stripes, Mach's suit is white with red stripes, along with some black. Overall seeming to indicate that they are of similar origin, as well as reflecting Shinnosuke and Gou being seemingly opposite in personality.
The supposed Special Effect Failure from the Gunman arc, with Slowdown done by really awkward jerking around and no Overcrank, is actually the result of the hatted Roidmude making a bunch of Slowdown rings all at once to trap our heroes. What happens when you crank out too much of a product too soon? You sacrifice quality.
Type Dead Heat being able to copy Heart's Dead Zone power makes perfect sense when you remember that the Roidmudes were based on Drive's systems. It makes sense that the Roidmude's power might be backwards compatible.
Chaser being able to go toe-to-toe with Drive and Mach despite them being newer and stronger than the former makes sense when you think about it. Remember, Chase was once the Rider who stopped the Global Freeze on his own, WITHOUT upgrades or power-ups. He's a character who learns by experience!
Why does Drive Type Dead Heat have Mach's eyes on the back of his helmet? Like it was with the strange knob on OOO's back, it's a leftover for toy designs, as the Tire Koukan toy series can change between the two Dead Heat Riders with a single movement of the head!
If you look at the back of Type Speed, Type Wild, and Type Technic's helmets, they have a part there based on taillights. Mach's eyes, when upside down, just so happen to have a similar shape, so it kind of works.
There's actually a good reason why Chase becomes Kamen Rider Chaser instead of taking back the Kamen Rider Proto-Drive title. Chase and Proto-Drive are two different individuals! Chase used to be Proto-Drive, but the Proto-Drive personality was erased when Heart killed Proto-Drive. Chase was raised to protect the Roidmudes and occasionally take out the reckless ones while Proto-Drive was raised to protect humans, causing him to become the hero that single-handily stopped the Global Freeze. They might have the same nature but Chase and Proto-Drive were nurtured differently, making them two different Kamen Riders.
Medic relying almost entirely on Combat Tentacles, one of the cheapest and common Monster of the Week moves next to shooting spikes and teleporting away, but it makes a funny kind of sense as one of the first rules of combat medics is to look for immediate danger before acting i.e. not to get yourself injured as well.
Her other known attack is an intensely hot, focused laser scalpel. Not unlike a surgeon's deft hands, her attack methods seem to focus on precision.
On the subject of healing, it may appear to be TV Logic that Shinosuke was able to recover from his injuries sustained from Drive so fast, even from life-threatening ones (such as from the fight with Heart). From Episode 23, it was revealed that he does use Mad Doctor to speed up his recovery. Sure, it may hurts like hell but it is still effective like hell.
The placement of Kamen Rider Chaser's signal on the back may seem odd considering you wont be able to see what signal he has from the front but since Mashin Chaser's Tune weapons which are his equivalent to Signal Changes unfold from his back it makes sense that his Kourin signal would be placed there.
It took awhile for me to realize something: Type Formula and its Pit Crew correspond to Drive's previous Transformation Shift Cars (excluding the movie-exclusive one).
Type Dead Heat and Type Formula: The most powerful, but also dangerous to use over long periods of time.
Type Speed and Shift Mantarn F01: First Transformation/Formula Tire Exchange Shift Car to be used. The fastest of the three initial Transformation Shift Cars.
Type Wild and Shift Jacky F02: Second Transformation/Formula Tire Exchange Shift Car to be used. The Big Guy of the group.
Type Technic and Shift Sparner F03: Third Transformation/Formula Tire Exchange Shift Car to be used. The Smart Guy of the group.
#23-24 focus on the question of whether or not Mach should get more power ups to level the playing field. The in-universe justification for not getting more is that Gou is already strong. However, because of Type Formula coming into the fray and his mastery of Dead Heat, he has in a way gained a power up in the form of becoming the sole user of the Shift Dead Heat Car. He just had it all along.
Why was Chase, as Mashin Chaser, called the Grim Reaper even though he didn't destroy Roidmudes? It didn't make sense until you remember who he was prior. He was Proto-Drive, enemy number one and the one who stopped their plans in one night. Heart and Brain needed something to keep most of the Roidmudes in line, what better way to use the person that beat them, their own personal Grim Reaper?
The name "Global Freeze" makes more sense when Roidmude 001's Advanced Roidmude form's name was revealed to be Freeze.
Fear = the day when the Roidmudes went rogue. Anger = the fury Go felt when the Roidmudes ripped his and Kiriko's father from their lives. Hate = his anger against the Roidmudes grew intense enough to view the situation in a black/white picture. Suffering = Go's a little liberal with that hate of his, and Kiriko's usually in the center of it, thanks to her situation with Chase.
Go's resolve to kill all the Roidmudes and why he's doing it might not make as much sense, especially when he's concerned about Kiriko... that is until you recall the time where they took on Judge. The Victim of the Week's brother was killed by the real Judge and made to look like he was Judge the whole time. Because of her relation to him, she was cast as a black sheep. Go is actually trying his hardest to ensure that same fate doesn't befall Kiriko.
Judge also serves as foreshadowing to Shinnosuke's arc. His resolve to find out who killed his dad has him at one point fighting a Roidmude over protecting civilians. This isn't the first time a cop resorted to harming civilians over protecting them when it came to finding the truth. Not only that, but the reason the real Judge killed the the brother was because he helped him and the embarrassment was what pushed him to kill. Not only is that the exact reasoning for Eisuke's murderer, but that exact feeling both killers felt is what powers up the Freeze Roidmude: humiliation.
Drive's Insert Song is called "Don't lose your mind" and the big bad has the power to alter memories.
It should be noted that one of the moments where the song plays is after Shinnosuke starts refusing to lose his mind over his father's murder.
Everyone who lives in an area where it snows knows how the weather can be harsh on cars, from killing batteries to freezing vital fluids. Freeze manages to beat Drive, a car-themed Rider, by exploiting its vulnerability to the cold.
Each of the Prominent Roidmudes has a color or color scheme that counters the Riders and/or their forms while also sharing some aspect of the Rider. And given the need for certain emotions for the Roidmude to evolve and for Drive to use his multiple forms, its also quite fitting.
Heart and Drive Type Speed: Both are red and were the first of their respective factions seen.
Brain and Drive Type Technic: Both are green and Brain's motif goes well with the calm collectiveness needed for Type Technic.
Medic and Drive Type Wild/Type Dead Heat/Mach: Medic in her human form wears black which is Wild's prominent color, while her Roidmude form is predominantly white and red like both Type Dead Heat and Mach. Heck, her emotion of adoration can be seen as similar to passion which is needed for Type Wild, and as for her rivalry with Brain... Dead Heat refers to being neck and neck like rivals.
Freeze and Drive Type Formula/Type Tridoron: In the former's case, both are blue and yellow (though Freeze is not both at the same time). In the latter's case, the fact that it combines Shinnosuke and Mr. Belt makes both adversaries the strongest of their groups.
Lupin and Drive Type Fruit: Both have what can be considered an orange color and are movie-exclusive.
Chase counters himself obviously as both Proto-Drive and Chaser, though he can also counter Lupin.
The line "This Rider is a Driver" not only means that this year's Kamen Rider drives a car instead of a bike, but it also refers to Krim/Mr. Belt being able to take over Type Tridoron's body and be a Kamen Rider. After all, he is a driver.
Have you noticed that Shinnosuke/Drive did not appear in Gaim's summer film? That's because the storyline for Drive and its main rider are long after the events of Gaim. Like Gaim, Drive is a plot-heavy and timeline-loving series. If Drive's involved, that makes it canon, so they cut Shinnosuke out of the movie to avoid any complicated reasons to go into the past to help out a Rider trapped in an alternative world.
There's also the fact that it's tradition for the Kamen Rider making his Early-Bird Cameo to defeat an enemy that had been giving the current rider trouble. Considering that doing so would make Drive stronger than a literal god, Drive wouldn't have appeared regardless of how plot-heavy his series was - such a cameo so would a), make Drive the most overpowered rider since Decade, and b), continue the Power Creep that results from this, meaning that if they didn't have Drive break the trend, Ghost would have to in order to stop the Power Creep.
The Riders see Roidmudes as the enemies of mankind, while Roidmude see the Riders as the enemies of their kind. How fitting that Banno becomes Golden Drive using a Roidmude.
Kamen Rider Chaser is chrome, same as Type High Speed. It's fridge because High Speed is an 'upgraded' version of Speed. Mach and Chaser are not that obvious, but if you used their respective Signal Bike with the Drive Driver and Shift Brace, you would get Type Next and Type Get Next respectively. Chaser's Signal Bike is an upgraded version of Mach's!
Notice in Medic's flashback in #42 where it didn't explain how she got her Advanced Roidmude form? She probably unlocked it sometime after absorbing negative emotions from other Roidmudes while healing them, attributing to her uncanny appearance.
004 was built by Banno to be Krim's replacement. Instead of being a Cobra-type, Bat-type or even a new animal, it was built as a Spider-type to double as replacing 002, following the previous flashback of Banno busted for mistreating 002.
Banno ends up taking over the body of 006, a Cobra Roidmude. A snake. Now think of that in the context of how he treated his son and Krim and the coloration between serpents and deceivers. Quite fitting really.
Gold Drive's ability to hijack weapons of other Riders that were already in use make him fittingly a Carjacker since Banno stole most of Krim's inventions and twisted them to his use, hijacking them for his pleasure. If a Rider's a Driver, a Rider, or a Chaser... then this evil Rider's a Carjacker.
Go kills Banno the same way that Shinnosuke killed Krim in the movie, but uses the Full Throttle. Remember that Krim has been rebuilt several times. Go was making sure there wasn't enough of Banno to be put back together.
The first two arcs are made to introduce the main and second rider (Drive and Mach) while the two arcs that make up the end game both share the same theme: gaining closure with their fathers.
In episode 47, Ghost shows up to protect Shinnosuke from the spirits of Freeze, Sword, and Thief. Sword's host tried to kill Shinnosuke's partner, Thief's host had a long-held hatred against the Tomari family, and Freeze's history with Shinnosuke should be obvious. They're not random choices to show up, they're the three destroyed Roidmudes who would have the biggest personal grudges with Drive, grudges which tend to make deceased souls into Youkai specters.
Near the end of the music video to Spinning Wheel, Kiriko appears to all three Riders. While Go and Chase walked away from her, Shinnosuke was the only one to walk towards her. This could represent the romance subplot done late in Drive between Chase, Shinnosuke, and Kiriko. Go is the first to walk away due to his connection with Kiriko being of blood and not of love. Chase is the second, knowing full wellthe two love each other (and possibly mirroring his moment in #44) while Shinnosuke ends up marrying her.
How fitting that Heart is killed with a stab to the heart.
When used with the Drive Driver, the Chaser Signal Bike reads as "Type Get Next". "Get Next" could be seen as synonymous with chasing the future.
Roidmudes get Stronger with Age. Roidmude 108, while a dangerous psychopath, is thus presumably the weakest. In the present at least. In the future, and when he's in the present, he's very powerful and defeated the future (presumably stronger) Drive without evolving. Because at that point he's the oldest surviving Roidmude!
The NEXTridoron is based on Mercedes-AMG GT, which is obviously an outdated model 20 years in the future. It looks like a case of Zeerust at first glance. But then we are shown the First Drive Pit, which has been repurposed as Krim storeroom for his vintage cars collection. It's not that Krim can't afford to buy more recent cars, he just prefers classic automobiles.
Also, Drive's Tridoron is based on Honda NSX, which came out on 1990.
Heart and Medic being in love with each other is more than just the Florence Nightingale Effect. Heart is grateful that this beautiful woman not only healed him, but also healed the other Roidmudes, all of whom Heart cherishes as his valued friends. On her own end, Medic absorbs the emotions of Roidmudes that she heals, and Banno's evil chip of negative human emotions was implanted in nearly every Roidmude except Heart. Healing other Roidmudes is what corrupted Medic into the cruel sociopath she is through most of the series, so she's attracted to Heart because healing him literally fills her with his positive feelings and love, something she experiences from no other Roidmude.
Type Speed Wild Technic being cobbled together from Drive's various forms actually makes perfect sense. Drive has alternate forms which colors match with the Roidmudes trio (Red = Type Speed/Heart, Green = Type Technic/Brain, Black = Type Wild/Medic). So basically Type Speed Wild Technic symbolizes the union of Heart, Brain, and Medic in one body.
Watching Drive after Gaim, Belt-san's secretiveness is quite sinister. Remember Bando's speech about how somebody who is keeping a secret from you can manipulate you into doing whatever they want?
Drive using Mad Doctor to help injured people comes as this when you remember that when it was used... it caused Shinnosuke to scream in pain.
Presumably the Cure Quicker only has that effect on Drive, seeing as he's a Rider, and can take it. Otherwise, Mad Doctor would be doing more harm than good to ordinary humans.
Actually it was stated the full throttle is what caused the overwhelming pain. Shifting the car three times would not do any harm against regular humans, otherwise Mr. Belt would've warned Shinnosuke against this.
Episode 34 shows Drive using Mad Doctor's power on a civilian in a method that is clearly painless.
Go's mentality on dealing with Roidmudes ranging from using Slowdown and lack of mercy towards Roidmudes and anyone working with them serves more than just a direct and stark contrast to Shinnosuke's more professional and more justice-based approach when it comes to the same situation: it's basically the American cultural view of justice vs. the Japanese's.
To elaborate, America has recently been the center of police controversy along the lines of killings in police custody, excessive use of force, and overall incompetencey. Japan, on the hand, has no such problem in their police force. It would make sense why Go's suggestion of killing evil humans working with Roidmudes so appalling to Shinnosuke and Kiriko, being that the former lived in America for quite some time.
Add in the fact that much of said brutality are also said to be hate crimes, and you have Go being a racist cop.
Roidmude 108 is set to appear in The Movie. 108 was apparently so awful that his fellows imprisoned him. Keep in mind how Heart feels about his people and that most Roidmude trouble makers get reset. What did 108 do that the Roidmudes saw as so horrible that imprisoning him was needed?
Slightly less scary fridge horror, but there could be an explanation for Nira's departure near the end of the show. He was convicted for murder, among other crimes. Usually these lead to a death penalty.
If it helps, the plot of Kamen Rider Drive: ~Mach Saga~ involves Nira, along with other human criminals who allied with Roidmudes, escaping from prison. Not exactly a good thing, but at least we know he's not dead yet.
Banno (using 006's body) becomes a lot more terrifying when you consider the fact he's basically a ghost possessing a corpse.
Back when the first 9 Roidmudes gathered before the Global Freeze, how much did Banno know about their plans, given his servant 004 is among them. In fact, through 004, how much did Banno contributed to it?
004 Probably suggested that they kill Krim.
One has to wonder if 004 was the only Roidmude that was in on Banno's plan. After all, Freeze was the one telling the other Roidmudes how to unlock their super evolutions, something Banno needs for his endgame.
During Episode 0, we hear Heart saying they're going to give 'humanity that word they love so much. 'Revolution.' We learn later in the episode that a terrorist group called Neo Shade were performing terrorist attacks and justifying it as a 'revolution' before the Global Freeze. While this likely contributed to the Humans Are Bastards mentality the Roidmudes have, it's somewhat terrifying and sobering to consider the idea the Roidmudes learned how to perform a 'revolution' from Neo Shade...especially considering such terrorists really do exist.
Banno saving Yukari from an incurable poison wasn't him being a nice guy. It was him giving a sneak peek of his master plan.
So here's a thought, Do Krim's friends and family know that he's currently a belt?
We don't know if he has any family but as for friends Jun and Harley know about him being a belt
He outright said that he was a lifelong bachelor and had no family of his own, so it's most likely that anyone who would know him is already aware of his current state.
More of a Fridge Sorrow than a Fridge Horror. Chase still lives in the form of his human copy so it's like he hasn't died, right? Wrong. Anyone who has heard the phrase "we'll get you a new dog" would know how wrong that is, as a new dog will not be exactly like the old dog that passed. Same goes with Chase and Koichi. While Koichi looks like Chase and might even act like him, he hasn't had the same experiences, reactions or bonds that Chase had.
Thanks to Drive's addiction to making everything canon, the Global Freeze took place shortly after the Helheim invasion. Meaning that while humanity was recovering from an invasion from a world filled with killer plants and bloodthirsty human-turned-monsters, robots came out of nowhere and attacked a quarter of the world. It must have sucked to be a normal, faceless civilian.
You don't need to be normal to suffer from that truth...As Drive makes everything canon, including previous Kamen Riders' existence, this leads to a terrifying thought: Most Rider enemies can be beaten by any Rider from any series with enough skill and power, even though some may be tougher than the rest. Enter the Roidmudes; They literally has the power to slow down time, whose effects on non-Drive Riders aren't quite clear yet. But if only Drive Riders can cancel it, another Rider might be get their ass kicked during Global Freeze, assuming they even have time to Henshin, that is...
Following the above Fridge Horror, according to Freeze, he has been in the Self Defense Force for 15 years. 15 years without ANY Riders before Drive found out about him! Are police forces in Kamen Rider that useless against monsters or every effort to deal with them was sabotaged by him?
It's likely that they're just that useless against monsters as opposed to being sabotaged by him - after all, the Roidmudes didn't team up with the Megahex in Gaim vs Drive, so odds are a), the monsters are species Freeze couldn't help in the events of the show they appeared in for some reason (i.e., the Imagin, Mirror Monsters), b), they would've been stopped regardless of if he hindered the cops (i.e., the Horoscopes, the Yummies/Greeeds), or c), that he didn't care about other species (i.e., the Makamou, the Fangires). In fact, the police were actually quite effective against the Gurongi and the Lords.
The near end of Zi-O reveals that the Rider homeworlds, including Drive's, were separate.
, which is obviously an outdated model 20 years in the future. It looks like a case of Zeerust at first glance. But then we are shown the First Drive Pit, which has been repurposed as Krim storeroom for his vintage cars collection. It's not that Krim can't afford to buy more recent cars, he just prefers classic automobiles.
