* CrazyAwesome: Titus, Steerpike, ''and'' Fuchsia!
* CreatorsPet: Titus.
* DracoInLeatherPants: Steerpike.
** Though even the biggest leather pants fetishist may have second thoughts when they read what Steerpike planned to do to Fushsia...
** It's more the [[FilmOfTheBook BBC Adaptation]] version of Steerpike who gets this treatment, and seems to encourage some fans to interpret the character differently. Although he was still [[MagnificentBastard pretty damn evil]], he was deliberately portrayed as genuinely loving Fuchsia (albeit in a warped and very disturbing way) and given a great stinking FreudianExcuse to boot [[note]] - a sob story wherein he had been abandoned at the age of six, sent to work in the kitchens and abused (emotionally, physically and sexually) throughout his childhood. In the novel, Steerpike, at seventeen, had arrived in the kitchens only a few months ago, so Swelter could not have abused him as a child. Peake tells us absolutely nothing about Steerpike's upbringing or origins (beyond the fact that he came from beyond Gormenghast) so we don't actually know if he has a tragic past to explain his extreme sociopathy[[/note]]. Casting the rather handsome JonathanRhysMeyers -- who ''really'' [[AdaptationalAttractiveness doesn't fit the picture of the ugly, hunch-backed albino]] Peake described -- apparently didn't hurt either.
** Bear in mind that this was EXACTLY THE POINT, as Fuschia was a young girl looking for escape in the arms of an outsider to her world. Steerpike is an unredeemable monster, that he's sociopathic enough to think playing to the girl's fantasies will get him ahead in life, he'll do it, with aplomb.
* DumbIsGood: With the exception of Prunesquallor, the intellectual characters are depicted as cold, calculating and ruthless, most notably Steerpike and Cheeta.
** Or detached, like Lord Sepulchrave.
* IconicCharacterForgottenTitle: A double subversion in that Mervyn Peake considered this a series about Titus, not Gormenghast. The novella "Boy In Darkness" and the third novel, ''Titus Alone'' take place outside of Gormenghast.
* MagnificentBastard: If Steerpike had only had a Manga/DeathNote, the books would have been over very, ''very'' quickly.
* MoralEventHorizon: Steerpike, the murder of the twins.
* ParanoiaFuel and NightmareFuel: The companion novella ''Boy in Darkness''. In its entirety.
* TheWoobie: Nannie Slagg. She's eighty years old, three feet tall, and perpetually on the verge of tears. Also, her husband died of a stroke on their wedding night.
** Steerpike was a bit of a woobie early on, particularly when you consider his non-person status among the other members of the castle. And most especially when you consider that Swelter was not only tremendously abusive to the kitchen boys (including Steerpike), but it is implied that he also sexually molested and cannibalised them. A childhood like that has to mess you up a little. Even if he didn't fit his leather pants quite so well, Steerpike would have started out as a SympatheticVillain, at least until his first or second MoralEventHorizon.
*** A lot of the aristocracy also deserve Woobie status, because although they are completely batshit insane and a little stupid, they aren't bad people. The [[TheOphelia Opheliac]] CreepyTwins Cora and Clarice didn't deserve such a prolonged and brutal death at Steerpike's hands. And Fuschia was just in love and insanely sheltered, with the hereditary insanity that seems to possess everybody in her family. You've got to feel a little sorry for her, too.
** The "Thing" was essentially ''born'' into Woobiehood, [[spoiler: although she dies too soon for Peake to really showcase this much.]]
