YMMV / X/1999

  • Anti-Climax Boss: Fuuma in the film adaptation.
  • Broken Base: Whether the manga will ever continue or not. Given that the manga had been put on hold several times until its official hiatus in 2003 due to mirroring Real Life incidents, some people find it understandable. Nanase Ohkawa mentioned that they'll continue the manga when they'll have a magazine that is willing to publish it. But it's already been a decade and CLAMP have four works in their table (two previous returned after their poor endings, one returned from a hiatus and a new one which went into a hiatus again). And since they currently working on Tsubasa World Chronicle while putting the three works on hiatus, X/1999 fans have given up hope that the manga will never return at this point. And considering some of the negative reception towards some of their newer works, you have some fans who don't want CLAMP to finish X/1999, thinking that their writing skills have declined and would only ruin it.
  • The Chris Carter Effect: X1999 remains on hold since 2003. Nanase Ohkawa, the lead writer of CLAMP, mentioned that they're still looking for a magazine willing to publish the remaining chapters. However, a decade had already passed and CLAMP put two more works on hold to work on Tsubasa World Chronicle, which is a continuation of Tsubasa Reservoir Chronicle and xxxHolic:Rei which is also a semi-continuation of Xxxholic. Fans of X/1999 are not pleased with this and doubt that the manga will ever continue at this point.
  • Crowning Music of Awesome:
  • Darkness-Induced Audience Apathy:
    • The movie version of X/1999 can be this since this was released while the manga was ongoing. The world is about to end as usual but both ended killing each other and dying at the same time. The Dragons of Earth are portrayed as mass murdering assholes which includes Kusanagi, who is known to be Token Good Teammate and a Friend to All Living Things. The Dragons of Heaven are still the good guys but they are slowly decimated along with the barriers they're protecting, which resulted to entire city completely destroyed with Tokyo Tower left standing. And in the end, Kamui is forced to kill Fuuma by beheading him which leaves him the only survivor in the cast. No wonder most people prefer the TV series and the manga.
    • The manga strays into this in the last chapters as well. The Dragons of Heaven are in a losing battle where Yuzuriha suddenly disappeared, Subaru defected to the Dragons of Earth after inheriting Seishirou's job with the belief that he wanted to help Kamui realize his "true" wish and Arashi became a pawn to Hinoto's evil side who is responsible for the mishaps that the group's experiencing. It also turns out that Kamui's "true wish" is not restoring Fuuma back to his original self. It doesn't help that the manga went a decade-long hiatus with a Cliffhanger which drove readers mad. Of course, most readers want CLAMP to continue the story. But due to CLAMP's recent works which have poor endings, some care less about it with the fear that the ending is probably be more depressing than the movie.
  • Deader Than Disco: Once used to be the HUGE giant of CLAMP. However, with the failure of CLAMP's recent works has caused fans to completely abandon the series, fearing that the same would happen to this.
  • Designated Hero: Kamui at first due to being a Jerk Ass who avoids contact with anybody. It should be noted that Yuzuriha and Sorata actually understand why he acts like that and Hinoto even reveals that he could actually destroy mankind depending on his development despite her visions of Kamui as messiah figure. Kamui finally becomes more likable when opening up to Kotori.
  • Die for Our Ship: Poor, poor Kotori.
    • And if you cross paths with a Seishirou/Subaru fangirl, don't mention Kamui. Similarly, saying the name "Subaru" in front of a Fuuma/Kamui fan can be as unwise as mentioning Kotori's.
  • Draco in Leather Pants: Fuuma and especially Seishirou.
  • Evil Is Sexy: Kanoe is the embodiment of this trope.
    • So are Seishirou and Yuuto.
  • Epileptic Trees: Oh, all the theories that have run around about Keiichi in CLAMP fandom.
  • Ensemble Darkhorse: There are a lot but two most popular are probably the energetic Sorata and the cold yet kindhearted Subaru.
  • Fanfic Fuel: They are probably a lot of fanfics which had a lot of What If? scenarios such as, 'what if Kamui joins the Dragons of Earth instead and Fuuma go to the other side vice-versa'
    • Though they are fanfics of Kamui visiting Yuuko's shop, CLAMP made a short comic of it in Clamp in Wonderland EX and Mokona jokingly said that the price of Kamui's wish will be the fate of the world and Watanuki scolded him for making Kamui cried. Fuuma appeared later on and declared that he's the only one who can grant his wish. Cue the two fighting again much to Watanuki's chagrin.
  • Faux Symbolism: A certain scene in The Movie, in which Kotori's dreamseer abilities manifest when Kamui sees her inside a room that looks as if it was filled with amniotic liquid, with the girl whispering "What is this Kamui? It's inside of me... it's gonna be born soon... I'll give birth to it soon...". Of course this refers to the Shinken, which Fuuma pulls out at the cost of her life in the end.
  • Ho Yay: C'mon, it's CLAMP. The most prominent case Kamui and Fuuma is later turned Foe Yay, natch. There are other common matchups as well, including Subaru and Kamui (mind penetration and Big Brother Mentorship FTW) and Fuuma and Seishirou (mostly for the symmetry, it seems). Seishirou and Subaru are far enough out of subtext and into text that Ho Yay doesn't really apply anymore.
  • Late-Arrival Spoiler: Can you guess who will be the main antagonist by checking the cover of a DVD?
  • Magnificent Bastard: Yuto and Seishiro are very good examples of this.
  • Memetic Mutation: "Yuuto is a PIMP!" "Kanoe is a hoe!".
  • Mind Game Ship: Both Seishirou/Subaru and Fuuma/Kamui qualify.
  • Moral Event Horizon: Fuma crosses it upon murdering his own sister (and VERY bloodily) to set off The End of the World as We Know It.
  • Narm: In the anime, the abundance of Off Model animation can seriously disrupt the mood.
  • The Scrappy: Kotori, because femininity and not being physically active is an unforgivable flaw according to many fans.
  • Ship-to-Ship Combat: Seishirou/Subaru VS Subaru/Kamui.
  • Wangst: Kakyou
  • What Do You Mean, It's for Kids?: The series is mistaken for Shōnen/seinen when it is shoujo. This is due to violent content and a dark story.
  • What Do You Mean, It's Not Symbolic?: This is essentially the Gospel According to Ageha. The major alteration from Judeo-Christian eschatology is the dualism, with the two sides evenly matched and only a slim moral advantage on the part of the Dragons of Heaven.
  • What Measure Is a Non-Badass?:
    • A lot of fans just love to bash Kotori for being not only an Ill Girl Yamato Nadeshiko, but for daring to be emotionally and psychologically damaged after seeing the birth of the second Shinken.
    • Kamui was HOTLY bashed and loathed by fans for daring to cry and angst over his shitty destiny and the terrible breaking of his, Kotori and Fuuma's bonds.
  • The Woobie: Kakyou, Kotori, Subaru, Kamui, Yuzuriha when Satsuki decides it's time for a very literal Kick the Dog moment and kills Inuki... a good chunk of the main cast, really. Not so strange when you consider that they're Team Keep Humanity Alive. Among the fandom, Subaru is the undisputed King of Woobieness.
    • Kakyou Kuzuki is a Dragon of Earth. Team Kill Humanity to Save the Earth isn't entirely without Woobies, you know? Outside the movie, pretty much everyone is a Woobie or just plain Affable. Fuuma's theme is granting wishes (read: Killing people who want to die), the Sakurazukamori assassin is a position apparently passed on by death at the hands of the one the current assassin loves (Seishirou killed his mom), Satsuki was used by first a father and then corporate businessmen who want to exploit her. Kusanagi is perhaps the only one on the Dragons of Earth who takes his side (though halfheartedly) because he's a nature-lover. (Oh, and he's ready to Back Stab FUUMA to save Yuzuriha.) Nataku hardly has a past at all because he's a clone. That leaves Yuuto, who's incredibly cheerful and friendly who's pretty much in it For the Lulz, and even then he wasn't fully evil as he has a sister he misses and genuinely cares for and refuses to take advantage of Satsuki's crush on him when he could've perfectly done so.
    • Nataku's case is ambiguous, since he might not have a proper past since he's a clone but in the manga what's left of the person he was cloned from's memories play a very important part in his very spoileriffic and sympathetic death. You could even make a case for the anime, as Fuuma absorbs Nataku's body to heal himself after Sorata almost kills him because of his Wish and former life's memories, in a sense.
    • Subaru was a Woobie before X even started, having lost his twin sister at the hands of their best friend / mutual love interest, Seishiro. Yes, Ho Yay and Foe Yay in a single package.
