* SugarWiki/AwesomeMusic: Pretty much their entire catalogue, although ''Ænima'' and ''Lateralus'' are generally considered their best work.
* 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.
* SugarWiki/FunnyMoments: "L.A. Municipal Court" and "Maynard's Dick".
** Also, "The Gaping Lotus Experience."
* GeniusBonus: Do you happen to be a kabbalah scholar, ConspiracyTheory 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. See ViewersAreGeniuses.
* 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.
* MagnumOpus: ''Ænima'' is usually considered this. Sometimes ''Lateralus'' gets the nod instead.
* MisattributedSong: For some reason, more than a few people think the theme song for ''Doom 3'' is by the band. It's a very understandable mistake, but it's actually by Tweaker.
** Before the release of the game, various sources claiming Tool made a song for it did ''not'' help matters much.
** Even more misleading is the fact that there were no vocals in the song.
* {{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.
* NightmareFuel: A lot of their videos, a few of their songs, and arguably the entire ''Lateralus'' album.
* 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 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.
