X (manga)/YMMV


 * Crowning Moment of Awesome: Seishirou's single-handed two-for-one kekkai special in Shibuya; trick with pop cans; Kakyou's corpse-puppeteering,.
 * Crowning Music of Awesome: A lot of piano players know about Naoki Sato's sublime Lonely Piano Piece Sadame which is Japanese for "Destiny" which is omnipresent in the anime in its symphonic version.
 * Draco in Leather Pants: Fuuma
 * Evil Is Sexy: Kanoe is the embodiment of this trope.
 * Epileptic Trees: Oh, all the theories that have run around about Keiichi in CLAMP fandom.
 * Ho Yay: C'mon, it's CLAMP. The most prominent case  is later turned Foe Yay, natch. There are other common matchups as well, including Subaru and Kamui (mind penetration 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.
 * × Seishirou was teasingly (and gloriously) hinted at when Seishirou defiled the Shibuya 109 building's kekkai with the blood of an innocent, sending it careening into the Shibuya Station, thus breaking both the Shibuya kekkai and the Yamanote kekkai in one fell swoop, something that the combined efforts of three Dragons of Earth could not achieve - only to watch it burn whilst discussing sampling delicacies from Tokyo's best restaurants before destroying them all.
 * 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
 * The Scrappy: Kotori, because femininity is an unforgivable flaw according to many fans.
 * Ship to Ship Combat: Seishirou/Subaru VS Subaru/Kamui. Heaven or Hell, let's rock!
 * Tear Jerker: Oh god, yes.  The anime and manga add many more.
 * There's a Tear Jerker for whichever character you like best, really.
 * Now has its own page.
 * Wangst: Kakyo
 * What Do You Mean It's for Kids?: The series is mistaken for Shonen/Seinen when it is shoujo. This is due to violent content and a dark story.
 * What Measure Is a Non Badass: A lot of fans just love to bash Kotori for being emotionally and psychologically damaged after.
 * The Woobie: Kakyou, Kotori, Subaru, Kamui, ... 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 that awful movie version, pretty much everyone is a Woobie or just plain Affable.
 * Subaru was a Woobie before X even started, having lost his twin sister
