Alternative Character Interpretation: A possible case mid-way through the show. Was Torque's attempt to turn Thrust against Xaviax a grab for power, or did he feel genuine remorse about what he'd done so far and wanted to make amends?
Awesome Music: Dragon Knight by Cage9 set the action with a heavy rock theme. Overseas markets like it so much it was featured arguably even more prominently than in the United States, even in Japan alongside its counterpart below.
Worth noting, defspiral contributed another piece of Awesome Music to Kamen Rider - namely, Leave All Behind, Accel's theme.
Broken Base: Kamen Rider fans are quite divided. Some think it's a great adaptation and there are even those who claim it's better than Kamen Rider Ryuki due to the storyline and American made footage being pretty good. There are those who hate it for various reasons, some of whom hate it just for existing.
Complete Monster: General Xaviax/Kamen Rider Wrath is a narcissistic alien warlord and the one behind all the tragedies throughout the series. Originating from the planet of Karsh, Xaviax devastated his own planet with a long-lasting civil war and proceeded to enslave civilizations from other planets, starting with Ventara. Having badly injured his former ally Eubulon and vented nine of the original Ventaran riders, Xaviax saw Earth as his next target. Kidnapping humans and leaving them in coma, Xaviax manipulated a group of people into becoming riders, taking advantage of Kit's love for his father, one of his victims. Xaviax's ultimate goal was to not only make humanity his next victim, but to hunt for the Ventaran riders who had escaped from him, especially Len. Succeeding in bringing riders to his side, Xaviax orders his right-hand man to vent the agents who he considers to be a loose canon, and was indifferent to his venting at the hands of a furious Len, possessing the body of a comatose patient to use him as his new puppet. Failing to achieve his goals, Xaviax made a final attempt to manipulate the riders before his death. While seemingly caring for his planet, his superficial charm, extreme methods and proud towards his own cruelty reveal his noble intentions as the empty excuses of an unfeeling tyrant with a superiority complex and a self-proclaimed evildoer.
Epileptic Trees: It's never directly stated what JTC stands for. Wrath's unique gold belt, sheer power, and a few mentions between Len and Vic seem to imply that Nolan, the original Wrath, might have been the leader of the Ventaran Kamen Riders.
Expy: Kit is a red Kamen Rider who has visions of an evil, black version of himself temporarily dies, comes back, and eventually gains the so-called evil power and uses it for good. Sound familiar?
"Funny Aneurysm" Moment: Xaviax jokingly tells JTC that he shouldn't forget to feed the Minions at one point. Well, the novel has the monsters turn feral and starts hunting people for food because Xaviax is not around anymore to keep them under control.
Game-Breaker: Wrath. And how! Especially in the actual Wii video game based on the series.
Germans Love David Hasselhoff: Although the show bombed in the US (the market it was made for) and was cancelled before finishing its run, Dragon Knight is insanely popular overseas, especially in Japan, with a DVD release and three music albums. DVDs also came out in Germany and Latin America. As a matter of point, Dragon Knight is so popular in Japan that they've started releasing action figures of the Riders - and these are specifically labeled as the Dragon Knight versions, not the Ryuki originals.
The Japanese are also lucky enough to get a sequel in the form of a novel.
Growing the Beard: The first five or so episodes are awfully slow, with the plot poorly explained and not even that many Monsters of the Week to fight. The pace picks up once Torque and other Riders start showing up and getting in each others' way.
Ham and Cheese: William O'Leary, the actor who plays Xaviax. Also Mark Dacascos while playing Xaviax in disguise.
As noted on the trivia page, Jason David Frank almost got the part of Len, but the producers chose not to give him the part, not wanting people to associate the series with Power Rangers. Apparently Toei heard about this and thought it was a good idea, because during the run of Dragon Knight, Kamen Rider Decade, the Kamen Rider series airing at the time, had a "World of Shinkenger" crossover arc, and 5 years later, it became a yearly tradition.
Story allusion crossing over with real life: You have a young man (18 years old to be precise) searching for his father and getting involved in much bigger plan, namely saving the world. It's ambigious what would happen if Kit and Tyler met, but Stephen Lunsford and Brennan Mejia seem to get along just fine, working together in Shot First Productions.
Probably a combination with Harsher in Hindsight: Dragon Knight has the message that end doesn't justify the means. It's source material, Kamen Rider Ryuki ponders over it at length, but doesn't make a solid statement. Then comes Kamen Rider Faiz, which starts with completely opposite statement. It's right there in opening theme - Justiφ's / end justiφ's the mean.
And it works really well in one of his last plans. Not only did he capture Earth's version of Len's old mentor, Kamen Rider Wrath, and turn him into little more than a puppet for his own whims, but Xaviax posessed Wrath and used him in open combat against poor Len. And when it looked like Xaviax was finally vented, he stood laughing as Wrath's body was dissolved into the Advent Void, grinning at Len. And then he took Kit's deck, just to rub in how pointless his sacrifice was.
Mis-blamed: It's frequently believed that DK was cancelled by CW 4Kids; in truth, the last two episodes just didn't air before the cut-off point where old shows were cycled out for new ones. CW actually really liked the series and continued to market and air the show despite low ratings, it was just a time policy they couldn't break.
Moment of Awesome: When the Cho brothers confront Len for the first time, arrogantly assuming they have a two-to-one advantage, Len gives them a lesson in humility by snatching their decks right out of their hands and kicking their asses all over Ventara, all without transforming.
Kit and Adam announcing their entrance with a double Strike Vent against Xaviax.note It doesn't hurt to realize that this is something fans of Ryuki had been begging for since Ryuga (Onyx's Japanese counterpart) first showed up in the Ryuki movie.
Special Effect Failure: You can quite easily tell when the show switches over to Ryuki footage- that show plus Faiz and Blade all had this odd, videotape-style effect over the images, making the footage look soft and a bit blurry.
Tear Jerker: A huge one in episode 19. Chris gets vented protecting Len from Strike's Final Vent. The only thing that makes it sadder? Len and Kit saluting, fist over heart, as Chris did when as he disappeared from existence. Semper Fi, Chris. *sniff*
They Wasted a Perfectly Good Character: Camo is barely in two episodes before he gets vented. We never see his Final Vent, his Advent Beast, or- probably his most interesting ability- Copy Vent. note Camo's Ryuki counterpart- Kamen Rider Verde- has the ability to take on the appearance and powers of any Rider he's fighting. If the Dragon Knight Wii game is to be believed, Camo has this power too, but never gets the chance to use it.
Cerebeast- the result of Strike's Advent Beast fusing with those of Sting and Thrust- is only briefly seen in one episode and never really put to any use.
To a lesser extent, Spear- who gets vented after barely being in four episodes and whose Advent Beast and Final Vent we also never see.
Incisor was only in three episodes before being vented, but his status as The Scrappy meant most weren't too broken up about that.
