* AudienceAlienatingEra:
** The most die-hard Celtic Frost fans can't stand up for ''Cold Lake''.
** Even those that champion ''Cold Lake'', refuse to defend the ''Prototype'' demo. This includes Tom G Warrior, who has tried to at least explain why ''Cold Lake'' was even made to begin with (he had just come out of a grueling battle with his record company and "was all to willing to let the darkness go, all the way up to the music.") [[HeWhoMustNotBeNamed He's made no such attempt for Prototype.]]
* SugarWiki/AwesomeMusic: ''To Mega Therion'' in its entirety, particularly "Circle of the Tyrants".
** ''Monotheist'' is this, as well as a meta example of SugarWiki/MomentOfAwesome, being considered by many as a [[WinBACKTheCrowd triumph return and redemption]] from the abysmal ''Cold Lake''
* CompleteMonster: "[[https://www.youtube.com/watch?v=L5prpJMrWhs Into the Crypts of Rays]]": UsefulNotes/GillesDeRais was a French marshal who fought alongside [[UsefulNotes/JoanOfArc Jeanne D'Arc]] as her personal guard. A rich nobleman, Gilles found himself deep in debt after squandering his wealth on lavish living, resorting to dabbling in mysticism and the occult to increase his riches. Gilles enticed several children into partaking in his black masses where he [[WouldHurtAChild sexually abused]] and [[HumanSacrifice sacrificed them]] to different demons. Gilles took sadistic delight in snuffing out the lives of his [[SerialKiller 140 victims]].
* FandomEnragingMisconception: Anyone in the black and death metal communities will tell you this: it is pronounced ''keltic'', not ''seltic''.
* GatewaySeries: Celtic Frost is probably one of the most common gateway band into black metal, particularly among thrash listeners, as they, along with Bathory, early Sodom, Venom, Hellhammer, etc. are part of first-wave black metal. They have also gotten many people into death metal.
* MemeticMutation: '''UGH!!!''', Tom G. Warrior's signature scream. May reach NarmCharm.
** "''Cold Lake'' was a time when [[TheWoobie Tom G. Warrior]] was happy."
* {{Narm}}: ''Cold Lake'', in all its hated glory is this for fans, due to the band trying ''very'' hard to become glam metal, with [[EpicFail hilarious results]].
** The demo ''Prototype'' is all of this, especially the infamous "[[https://www.youtube.com/watch?v=Ndrcz3mybPg Hip Hop Jugend]]", which one commentator said it sounded like a "rejected [[Music/{{Rammstein}} Rammstein]] song".
* NarmCharm: Their early material can be this by today's standards. Between Tom's LargeHam vocals and the band's over the top SwordAndSorcery aesthetic, the whole thing can come off as being a little ridiculous. That doesn't change the fact that it ''fucking rules''.
* NightmareFuel: The music video for "A Dying God Coming Into Human Flesh."
** Actually, ''Monotheist'' in general is this trope.
*** Considering that ''Monotheist'' '''surpasses''' the DarkerAndEdgier aspect, especially with "Triptych" piece. Brr...
** "Tears in a Prophet's Dream", a MindScrew instrumental track on ''To Mega Therion.''
* PeripheryDemographic: They are ''massively'' popular among fans of HardcorePunk and were a gigantic influence as a whole, particularly on beatdown acts. Music/{{Hatebreed}}, in particular, was so heavily influenced by them that Jamey Jasta regularly referred to them as "Celtic Frost hardcore" to describe their style.
* SuspiciouslySimilarSong: Compare the main riff of "Cherry Orchards" to the opening riff of [[Music/{{Metallica}} "Seek and Destroy"]].
** For that matter, the riff from "Dethroned Emperor" to the one from [[Music/DiamondHead "Am I Evil?"]].
* TearJerker: While their early records were "dark" in a more silly fashion, ''Monotheist'' encapsulates a more genuinely grim tone. "Drown in Ashes", "Obscured", "A Dying God Coming Into Human Flesh" (Also NightmareFuel) and the final part of the triptych "Winter" all deserve note.
* TheyChangedItNowItSucks: ''Cold Lake'', big time.
* VindicatedByHistory: A minor case, but ''Cold Lake'', while still Celtic Frost's least popular album by a large margin, has since started to be viewed as SoOkayItsAverage as opposed to the universal hatred it when it was first released, with reviewers pointing out that if you look at it in a vacuum, rather than try to compare it to the band's regular sound, it's a pretty decent HairMetal album.
* WinBackTheCrowd: ''Monotheist'' got this for many fans, especially for those who feel it was a perfect close for Celtic Frost.
