* NiceJobBreakingItHero: Saitou and Shun [[spoiler: succeed in waking the [[{{GodInHumanForm}} Earthkami]] to stop [[{{GaiasVengeance}} D's army]], which ends up causing the collapse of civilization.]]

* KillerRabbit: Yukito and Ryou. Both are quiet, calm, and sweet, but [[spoiler: {{EmotionEater}} both are able to drain life energy to the point of death]].

* KillerRabbit: Yukito and Ryou. Both are quiet, calm, and sweet, but [[spoiler: {{EmotionEater both are able to drain life energy to the point of death}}]].

** Kaworu [[spoilers: likes to troll whole dimensions. And he gets away with it.]]

* Sliding scale of immortality and aging:

** CompleteImmortality: Angels, kami, and chaos demons are both unaging and cannot die from normal means (although there is the GodNeedsPrayerBadly clause and they can 'lose their connection' to the place or idea they represent). This list includes Bakura, Rune, D, Kaworu, Folken, Yue, the Earthkami, eventually [[spoiler:Saitou, Shun, and Aoshi]], and possibly Yukito.

*** [[spoiler: Confirmed after a hundred years of Kenshin's companionship allows Mamosei to become a sword youkai in his own right.]]

*** [[spoiler: Becomes a Living Weapon after a hundred years of Kenshin's companionship allows Mamosei to become a sword youkai in his own right.]]

* PhysicalGod: Rune, D, the Earthkami, and all the other kami, including eventually [[spoiler: Saitou and Shun]] are gods with physical form.

* FantasticRacism: Japan's, and particularly [=KaibaCorp=]'s, views toward youkai ever since they wouldn't intercede in some [[{{WorldWarII}} petty squabble]] is somewhere between "racist" and "Holocaust".

* WellIntentionedExtremist: Saitou [[spoiler: when he assassinates the generals in 1942 to try to stop WorldWarII]]. D’s army-gathering to try to protect the Earth. Aoshi [[spoiler: when he destroys the government]], arguably.

** The Ageless: Vampires, daiyoukai, dragons, tsukumogami, and most of the super-mortals fall into this, people who no longer age but can die of violence and misadventure. This list includes Kenshin, Aoshi, Hiko, [[spoiler:Seth]], Rei, Sesshoumaru, Shun, Hana, Kurama, Abel, and possibly Yukito.
** CompleteImmortality: Angels, kami, and chaos demons are both unaging and cannot die from normal means (although there is the GodNeedsPrayerBadly clause and they can 'lose their connection' to the place or idea they represent). This list includes Bakura, Rune, D, Kaworu, Folken, the Earthkami, and eventually [[spoiler:Saitou, Shun, and Aoshi]].

* TheAgeless:
** The vampires settle into a kind of stasis in the appearance of about age 20 (save Hiko, who is worldweary and might look 30).
** Kami are born fully-formed and never change except in response to their environment.
** Daiyoukai also seem to stop aging, though it's never explained; Sesshoumaru seems to look the same forever.
** [[spoiler: Saitou ends up looking about 30ish once he reverts after dying from old age and being saved.]]

* ResurrectiveImmortality:
** Yoko no Kurama keeps coming back to life, to the heroes' chagrin.
** The vampires can be resurrected continuously as long as their master is around.

* OneManArmy: Many youkai, but Sesshoumaru, Kenshin, and Aoshi specifically, in very different ways. [[spoiler: Sesshoumaru has only to take his true form to beat back an attack from the government and [=KaibaCorp=]. Kenshin has to channel his ki into maintaining a force field and boil magma, and still meditate on top of it, to keep his people safe from him in the apocalypse. Aoshi's attack on the Diet leaves about 500 people dead with nothing but his swords.]]

** Atem, [[spoiler: Seth]], and Rei are another longterm threesome, though on less equal footing.

* AbortedArc: Koenma tells Kenshin he may call on them again, which goes nowhere.
** And Saitou's control-collar on Aoshi, which seems to've disappeared over a time jump.

* TheAgeless: The vampires settle into a kind of stasis in the appearance of about age 20 (save Hiko, who is worldweary and might look 30). Furthermore, kami are born fully-formed and never change except in response to their environment. Daiyoukai also seem to stop aging.

* AndIMustScream: [[spoiler: Saitou and the rest of Kurama's victims]] are kept alive long, long after they should be dead while he experiments on them.

* BadassNormal: Saitou deals with the government, youkai, vampires, demons, and kami, all while refusing to be given any supernatural upgrades. He remains a normal human, with the only allowance made for the result of Aoshi's ImpossibleTask.

** AncestralWeapon: Ookami no Hantei

** And MissingMom. Kitsune apparently aren't very maternal.

* ExtraParentConception: At least two of Yuki's children: Yue, whose fathers are Bakura and Ryou, and [[spoiler: Mamoru, whose fathers are Saitou and Kenshin]].

* GaiasVengeance: The kami D raising an army of dissatisfied youkai to wage war on humans because they are damaging to the natural world.
* GenderBender

* HotBlooded

** HalfHumanHybrid / {{Dhampyr}}: Kenji, who also gets an understated case of the above. [[{{InformedAbility}} He's supposed to be very powerful]], but he's too down-to-earth to use it.

** Also Seth - his specialty opposite Seto's force. Up to the level, [[spoiler: post-apocalypse and to Atem]], of ManBehindTheMan.
** Atem also goes for this, but sometimes falters at SmugSnake level as his sadism distracts him.

* MeaningfulRename: Aoshi, when [[spoiler: Bakura's chaos mark is changing him]] - the kanji of his tattooed name changes from the canonical spelling, which reads "blue + violet", to reading "blue + death".

** Aoshi is the amoral sidekick to [[{{TechnicalPacifist}} Kenshin]], who retains his vow not to kill, and [[{{LawfulGood}} Saitou]], who still believes in the law.

* EmpoweredBadassNormal

* LoveRedeems: Bakura[[spoiler:, on finding a mortal soulmate he admits to loving, loses his status as a chaos demon.]]
** A more subtle example: the love and unwavering faith of his child changed his nature to suit expectations. Not metaphorically, either - chaos is malleable.

* StrongerWithAge: Youkai in general and ryu-youkai in particular grow stronger as they get older. In addition kitsune are explicitly stated to store 100 years of power in a tail

* TheUnmasquedWorld: As of the 1940s TheMasquerade began shattering, due to Japan recruiting youkai for warfare. Within Japan, it was a slow creep starting several decades earlier, resulting from Aoshi revealing himself to Saitou.

* AndIMustScream: [[spoiler: Saitou and the rest of Kurama's victims.]]

** Harming [[{{PapaWolf}} Kenshin's family]] is enough to sometimes break his ThouShallNotKill vow.

* FantasticRacism: Japan's, and particularly [=KaibaCorp=]'s, views toward youkai ever since they wouldn't intercede in some [[{{WorldWarII}} petty squabble]].

** {{Twincest}}: Yuugi and Atem, mostly implied.

* JerkAssHasAPoint

* PhysicalGod: Rune, D, the Earthkami, and all the other kami, including eventually [[spoiler: Saitou and Shun]].
* PoisonousFriend: Aoshi to [[{{TechnicalPacifist}} Kenshin]], who retains his vow not to kill, and [[{{LawfulGood}} Saitou]], who still believes in the law. As well, [[spoiler: Bakura]] to Seto. Or he would be, if Seto had any compunction using him to his fullest.

* ThePollyanna: Yukito. S/he seems determined to be optimistic and kind, (almost) no matter what and to whom.
* {{Polyamory}}: Kenshin, Aoshi, and Saitou are the canon OT3. With flavors of open relationships and EthicalSlut, since they all sleep with at least one other person and it's not considered cheating or a big deal.

* PutOnABus: [[spoiler: Jounouchi, Mokuba, Yuugi, Yukito's babies, and Kenji's girlfriend and unborn child]], for their own protection.

* ResurrectiveImmortality: Yoko no Kurama, to the heroes' chagrin. The vampires as long as their master is around.
* {{Sadist}}: Atem, particularly [[spoiler: post-apocalypse.]]
* ScarfOfAsskicking: Aoshi's outfits usually include one from 1882 onward. Semi-justified, in that he's protecting his vulnerable throat.
* SeparatedAtBirth: Atem and Yuugi
* ShadowWalker: Bakura teleports this way, with amusing results.

* StalkerWithACrush: Bakura, who has no concept of respecting boundaries.

** Or as Bakura put it: "She won't kill you, but She'll put you into a position where you'll kill yourself."
* ToHellAndBack: Both Aoshi and Sesshoumaru.
* {{Tricksters}}: Bakura is a chaos demon, and Atem and Yuugi are both part kitsune.

* TheUnmasquedWorld: As of the 1940s, due to Japan recruiting youkai for warfare. Within Japan, it was a slow creep starting several decades earlier, resulting from Aoshi revealing himself to Saitou.

* WellIntentionedExtremist: Saitou [[spoiler: when he assassinates the generals in 1942]]. D’s army-gathering. Aoshi, arguably.
* WhatTheHellHero: Several people to Aoshi [[spoiler: after he massacred most of the Japanese government.]]

* DoorstopBaby: Atem, though at least he is given to his real father.

** [[spoiler: Seto gets cursed with this for pissing off a kami. In his case it's controlled by water, a la Ranma.]]

* HeroicBSOD: Kenshin, usually related to his vow not to kill and sometimes to his family.

* ILoveYouVampireDad: In this case generally overlaps with MentorShip: master-little one relationships are both mentorly and sexual. The cases when they become romantic (Kenshin and Aoshi, [[spoiler: Seth and Rei]]) are the exceptions.

* TheAlcatraz: The youkai prison in 1942 is on an uninhabited island in the north, mostly underground, with layers and layers of locked doors, and ''then'' surrounded by a holy energy barrier.
** ExtranormalPrison

* BerserkButton: Harming [[{{PapaWolf}} Kenshin's family]] is enough to sometimes break his ThouShallNotKill vow.

* BreakTheHaughty

* MassivelyMultiplayerCrossover: The main series is ''Manga/RurouniKenshin'', but there are major characters from ''Manga/YuGiOh'', ''Manga/CardCaptorSakura'', ''SaintSeiya'', ''Manga/DragonKnights'', and ''Manga/NeonGenesisEvangelion''. There are also minor characters from ''Manga/SailorMoon'', ''Manga/YuYuHakusho'', ''Manga/InuYasha'', ''Manga/PetShopOfHorrors'', ''Anime/{{Free}}'', ''LightNovel/TrinityBlood'', and ''Manga/{{Saiyuki}}'', as well as a ''[[Anime/{{HellGirl}} Jigoku Shoujo]]'' cameo.

** IntercontinuityCrossover: Some characters are just lifted completely out of their canon universe and dropped into the Rurouni-Kenshin-with-youkai baseline, including Card Captor Sakura and Yu-Gi-Oh characters, completely repurposed.
