!!The TV series
* CompleteMonster: [[MorallyAmbiguousDoctorate Doctor Randall]], from "Parts Unknown", is the head of an [[OrganTheft organ trafficking ring]] that is operating out of Long Island. Using a health club called the Fitness Factory as a front, Randall [[DeathFakedForYou fakes the deaths]] of the club's healthiest patrons by exposing them to a paralytic neurotoxin so that he can later dig up their graves and kill for them real by harvesting their organs for sale on the BlackMarket. When a pair of teenagers stumble onto the latest grave exhumation, it forces Randall's henchmen to quickly [[BuriedAlive rebury the victim]], who suffocates while trying to claw his way out of his coffin; the incident attracts the attention of Jonathan [=MacKensie=] and Edgar "Benny" Benedek of the Paranormal Research Unit. Randall is shown personally cutting the organs out of one of his abductees before having her disposed of, and he later tries to gun down both Jonathan and Benny to prevent his criminal enterprise from being exposed by PRU.

* UncannyValley: In ''The Eldritch", the people the Possessor controls move very awkwardly, as though the entity doesn't know how to simulate human movement properly.

* CopyCatSue: Shinjiro, especially in the first Shadowchasers fic where he was quite clearly the author's version of Yusei Fuso, right up with giving him a similar deck to Yusei's and a DarkAndTroubledPast with Yusei and even having an undefeated streak in the first fanfic, something the author was criticized over. Fortunately this was toned down in ''Power Primordial'' wherein he changes his deck and actually loses an important duel.

* HilariousInHindsight: The cards that Bruno uses in ''Tournament of Shadows'' are based on characters from ''Literature/AlicesAdventuresInWonderland'' with a much DarkerAndEdgier theme, including an older version of Alice using a Vorpal Blade as a weapon. The author first introduced these cards in a fic called ''Legacy of the Duelist'', which appeared ''years'' before [[VideoGame/AmericanMcGeesAlice a certain video game with similar themes]], was released.
* MoralEventHorizon: Several examples:
** [=DaPen's=] brutal MindRape of both Jinx and Gears in the first fic, along with the rather [[FateWorseThanDeath horrid description of his plans for them]] qualifies.
** The Aboleth from the second fic crossed this line a long time ago. It was willing to murder the populations of entire planets for no reason other than greed. It did so at least once, with the homeworld of the Primordial Titans, and tried to do so on at least one other occasion.
** In ''Torment'' Lorelei crosses it by her rather sadistic act of CruelMercy, turning Nichole into a cat after forcing her to try to win an antidote back from her (intending to keep her as a pet once the change becomes irreversible).
** Lareth damns himself by [[spoiler: turning on his partners, shooting them in cold blood in order to flee and save his own skin.]] Clearly, what ultimately happens to him is not undeserved.
** In ''Backwater'', Solex's in-story crossing is done when he and his entourage beat and gang-rape Kastleneid (his golem servant, purchased for the intent of serving as a SexSlave) and leaving her to die in a gutter like trash, for no other reason than to blow off steam following his public loss to Tsuki. Clearly, when a demon and a vampire are both sickened by your actions, it's clear you've gone too far.

* UnfortunateImplications: 7th Librarian changed Tsukihime's name to Tsuki via RetCon after research showed that it is inappropriate in Japanese culture to name a child after a deity.

* [[WinTheCrowd Win the Crowd Back]]: In-universe example. Part of the reason why Jalal agrees with the idea of the 2nd Duelist Kingdom tournament in ''Tournament of Shadows''. With their public relations with Shadowkind faltering lately, the tournament would be a great idea to re-establish themselves in the eyes of the Shadowkind community, especially if a Shadowchaser wins the tournament.
