* AwesomeArt: Alex Grey's iconic psychedelic album covers for ''Lateralus'' and ''10,000 Days''.
* SugarWiki/AwesomeMusic: Pretty much their entire catalogue, although ''[=Æ=]nima'' and ''Lateralus'' are generally considered their best work.
* BrokenBase: ''10,000 Days'' has a bit of a polarizing opinion among the fanbase.
* EpicRiff: ...and not just on the guitar. The bass intros to "Sober" and "Schism" are probably the best-known. It's pretty fair to say most Tool songs are built around an epic bass riff, with the guitar and drums adding a whole lot of texture and atmosphere.
* EpilepticTrees: Tool has so many of these that [[http://toolnavy.com/index.php there is a website]] dedicated to discussing them.
* FaceOfTheBand: Maynard James Keenan. On some tours he'll try to subvert the trope by performing at the back of the stage, silhouetted against a video screen.
* FunnyAneurysmMoment:
** "Hooker With a Penis" mocks fans for criticizing bands that they obviously like enough to buy their music in the first place. With the advent of file sharing, however, the song's triumphant calls to "buy, buy, buy" come across a little tragically now that audiences no longer need to buy music to criticize it. The speaker in the song is glorying in a power that no longer exists in the music world.
** The song "[=Æ=]nema" speaks about the suffering of UsefulNotes/LosAngeles, in usual TakeThat fashion towards the city of angels becomes disturbing considering the 2014-2015 drought that's plaguing not just LA, but ''California in general''.
* FunnyMoments: Every single line of ''Opiate'''s hidden track "The Gaping Lotus Experience".

* GeniusBonus: Do you happen to be a kabbalah scholar, UsefulNotes/ConspiracyTheories nut, musician, possess degrees in psychology and mathematics, and have a passing familiarity with drug culture? All at the same time? At this point you may, unaided, begin to understand just how many, ''many'' obscure references and in-jokes Tool loads their music and lyrics with. Being genuinely insane may or may not also help.
* ItsPopularNowItSucks: When Tool made their first steps toward popularity, some fans reacted with typical outrage, causing an obviously angry Maynard Keenan to fire back with the song "Hooker with a Penis," in which he mocks a typical fan for having ever "bought in" to his music in the first place.
* ItsTheSameNowItSucks: Most of the criticism leveled at ''10,000 Days'' is that it's basically just a slightly heavier ''Lateralus'', offering very little that differs from said album (for instance, the main riff to "Vicarious" is basically a [[SuspiciouslySimilarSong rewrite]] of a riff that appears near the end of "Schism").
* MemeticMutation:
** [[DevelopmentHell "So when is Tool's new album comes out?"]]
*** Related to this, claiming the title of ''10,000 Days'' as being the amount of time it will take for the new album to come out.
** "Tool hates [[FanDumb their]] [[MisaimedFandom fans]]"
* MisattributedSong: For some reason, more than a few people think the theme song for ''VideoGame/{{Doom 3}}'' is by the band. It's a very understandable mistake, but it's actually by Tweaker.
* {{Mondegreen}}: Given the lack of official lyrics and the at times distracting background sound, it's almost inevitable even for the lines that aren't completely indecipherable. Check three Tool fansites about how lyrics to any given song go, and you'll likely receive between two to five answers.
* NightmareRetardant: Finding out what "Die Eier von Satan" is actually about.
* ParanoiaFuel: "Faaip de Oaid".
* ReclusiveArtist: Maynard, primarily because he hates how famous musicians are deified and also because he's not particularly comfortable with fame to begin with. This has, among other things, resulted in him chasing stalkers off his property [[CrazyAwesome with paintball guns]].
* SignatureSong: "Sober" to many. "Schism" is also arguably their most played song. Most fans cite "Lateralus" as the best, though.
* TearJerker:
** "Wings for Marie/10,000 Days," seeing that it's an emotional tribute to Maynard's mother from Maynard himself.

** "Sober", which was written about a friend who had descended into alcoholism and co-dependency.
** "Disgustipated" can be considered this too if you consider the possibility that it's about how no lifeform on this planet is safe, animal, human or plant.
** "The Patient", enforcing the trope of GoodFeelsGood despite how bad things get.
* TheyCopiedItSoItSucks: Music/KurtCobain mentioned the music video for "Sober" as being very similar to [[DerangedAnimation the style]] of the Brothers Quay and was unimpressed, saying that the Quays could sue Tool for copyright infringement.
* TrueArtIsIncomprehensible: The kings of the trope, just look at the music videos or art work.
