!! Leviathan (Webcomic)
* BrokenBase: The series' switch to a webnovel format was contentious among readers. While some preferred the overall art-style of the webcomic format, other fans felt that the prose of the webnovel greatly benefitted the overall flow of the story.
* UnexpectedCharacter: ''Nobody'' was expecting [[spoiler:''[[VideoGame/LobotomyCorporation Schadenfreude]]'' of all abnormalities to make an appearance]].

!! Leviathan (The novels)
* AluminumChristmasTrees: The flechette bats seem absurd (what's a dart going to do against a warship?), but they're actually based on real WWI-era aerial flechettes. These were simple steel darts dropped from aircraft (either dumped out of the aircraft with a bucket or released from special belly-mounted steel containers) that were scattered over enemy trenches and infantry formations to wreak havoc. When dropped from sufficient height, they hit with enough force to pierce a steel helmet and the skull beneath it, or even [[AgonyOfTheFeet nail soldiers' feet to the ground]]. There was even discussion of using larger flechettes to [[ArmorPiercingAttack penetrate the roof armor of tanks]]. KineticWeaponsAreJustBetter, indeed.
* SugarWiki/AwesomeArt: Keith Thompson's [[http://img.sparknotes.com/content/sparklife/sparktalk/2014/westerfeldarttime_LargeWide.jpg insanely gorgeous]] illustrations expertly depict BioPunk and steampunk TechnologyPorn in equal measure and are a major draw for fans.
* AngstWhatAngst: Alek copes with his parents' deaths really well... It's especially jarring in comparison with Deryn, who's still pretty broken up about her father dying two years before the start of the story.
* CrazyIsCool: Zaven. So much. Nikola Tesla is even crazier, and even more awesome.
* EnsembleDarkhorse: [[UsefulNotes/NikolaTesla Nikola Tesla]], to the surprise of exactly no one who knows their history well.
* HoYay: Loads [[SweetOnPollyOliver between Alek and "Dylan"]], mostly in ''Behemoth''.
* IKnewIt: chapters 78 and 80 of the fanfic collection Fanfic/QuitePeculiar made up a two-part story arc called "Fit to Print". They were uploaded just weeks before the release of ''Goliath'', and made a spot-on prediction on how [[spoiler:Alek learns about Deryn's gender]] in the book: by [[spoiler:reading a newspaper article about her father's accident]].
* LesYay: Lilit. Her last line to Deryn before she leaves implies that she figured out that Deryn was actually a girl, and this is ''after'' she kissed Deryn full on the lips and said she was "just curious."
** "I know you better than you think, ''Mr''. Sharp." (Cue chuckling from Bovril.)
** It's worth noting that Deryn doesn't seem too bothered by it, either.
----> '''Alek:''' That girl is quite mad.
----> '''"Dylan":''' Aye. But she's not a bad kisser.
* NarmCharm: [[spoiler:Alek and Deryn's declaration of love at the end of ''Goliath'' is pretty cheesy, but it's pretty sweet as well.]]
* PortmanteauCoupleName: Dalek has become quite popular in the fandom for Deryn/Alek...no, not [[Series/DoctorWho that Dalek.]] Volger and Barlow also have Varlow.
* TearJerker: [[spoiler:Zaven's]] death.

!! Leviathan (The Band)
* ArchivePanic: '''So many demos''', that's all we can say. And that's not even ''going'' into Jef's other projects such as Lurker of Chalice, his involvement with Twilight, and god knows what else.
* SugarWiki/AwesomeArt: The album cover and supplementary artwork for ''Scar Sighted'', which [[TearJerker were made by Jef's girlfriend while she was dying of a brain tumor, and which he decided to keep.]]
** The rest of his album covers could also qualify, particularly ''A Silhouette in Splinters.''
* SugarWiki/AwesomeMusic: '''Everything''', most have been recently labeling ''Scar Sighted'' as his best work, although a majority of his albums such as ''The Tenth Sub-Level of Suicide'', ''Tentacles of Whorror'', and ''Massive Conspiracy Against All Life'' are considered this as well.
* BrokenBase: ''True Traitor, True Whore'' tends to be this for many people, if not helped due to the RealitySubtext over the allegations towards him by his ex-girlfriend. And even ''besides that'', most people find it very weak and underwhelming compared to the complex-like nature of ''Massive Conspiracy Against All Life''.
* CreepyAwesome: Jef is the living embodiment of this.
* EnsembleDarkhorse: ''A Silhouette in Splinters'', arguably due to it being Jef's experimental chance to dark ambient.
** Jef's secondary project Lurker of Chalice is this, due to being incredibly depressing and haunting, even ''more'' so than Leviathan.
* EpicRiff: He's more known for the atmosphere of his music, but he can still write some distinctive, memorable riffs when he wants to. "Aphonos" is a good example.
* JerkAssWoobie: Jef Whitehead had a very rocky childhood and it's clear growing up was rough for him, with him mentioning once trying to kill himself during the ''Tenth Sub-Level'' / ''Tentacles'' era of Leviathan, adding to the tragedy of his deceased girlfriend, who was his muse for Lurker of Chalice. At the same time of course, the controversies surrounding him in 2011 really doesn't paint a good picture of him, even if he did clean up his act in the end.
* NightmareFuel: Basically everything about his music, but ''especially'' his screams, which are just inhuman. Then there's the hateful, despairing, and disjointed tone of the music itself. It really isn't surprising when you learn about the dude's CreatorBreakdown.
** Again, his album covers. ''Tentacles of Whorror'' might be the worst one, because of how [[NightmareFace obscene]] it is.
** All of ''Scar Sighted'' is nightmarish, but the closing track, "Aphonos", might be one of the most apocalyptic, crushing things he's ever recorded. Between the brutalizing riff and Jef's tortured screams, it legitimately sounds like a nightmare. The haunting ambient outro doesn't help matters.
--> ''I wanna see it in your face. I wanna see it in your eye. '''I wanna see it in your tears'''.''
** The chaotic atmosphere of the first two albums really add a sense of paranoia and sense of TheNothingAfterDeath in ''The Tenth Sub-Level'' and the hateful fury of ''Tentacles of Whorror''. Special points with songs such as "The Idiot Sun" and "Vexed and Vomit Hexed".
*** ''Even non-metal stuff is unnerving'', the hauntingly depressive tone of the Lurker of Chalice debut and ''A Silhouette in Splinters'' can give a creepy vibe.
* TearJerker: Oddly enough, in the VICE documentary ''One Man Metal'', Jef opens up about his struggles when he was a teenager writing his first two albums, and then explaining his depression about the loss of his girlfriend Jesse.
** When he talks about Lurker of Chalice and mentions that the project had a "muse", only to pause and simply say... "…she’s dead, so I don’t think Lurker will happen again…" before looking away in sadness. The doc even shows a scene where Jef's showing interviewer JR Robinson a sketch he did of Jesse, along with a newspaper clipping of her obituary. He then mentions to JR how Jesse used to leave him little drawings each time he'd leave to work, before uttering a small but quiet "I've saved them all", ''showing that he did save all her drawings''.
*** It goes more into TearJerker territory when one looks at Jesse's little drawings and notices ''they're all the supplementary album art for Scar Sighted''. Gives the album a much more saddening vibe.
*** Lurker of Chalice's music also qualifies, considering how much more depressive it is than Leviathan. The intro to "Piercing Where They Might" and "Specter as Valkerie Is" are particularly sad.
** The title track of ''Scar Sighted'' definitely counts. The instrumental sounds almost like a funeral dirge, and the vocals are mainly just tortured, agonized screams.
** The majority of ''Massive Conspiracy Against All Life'' feels this way, especially considering it was essentially a [[GriefSong Grief Album]] about Whithead's deceased girlfriend, notably with the song "VI-XI-VI" being believed to be about her death (the Roman numerals being the date of her death) and being the only song off the record to not have its lyrics published.
* ValuesDissonance: ''Tentacles of Whorror'' and ''True Traitor, True Whore'' can cause some to quirk eyebrows due to it's misogynistic lyrics. While ''Tentacles'' can be chalked up to shock value (as the title track and "The History of Rape" seemed to be the only songs that have those type of lyrics), ''True Traitor'' makes it clear it ''is'' all of that due to it's RealitySubtext.
