- Awesome Music: Pretty much their entire catalogue, although Ænima and Lateralus are generally considered their best work.
- Broken Base: 10,000 Days has a bit of a polarizing opinion among the fanbase.
- Epic Riff: ...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.
- Epileptic Trees: Tool has so many of these that there is a website dedicated to discussing them.
- Face of the Band: 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.
- "Funny Aneurysm" Moment:
- "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 "Ænema" speaks about the suffering of Los Angeles, in usual Take That! fashion towards the city of angels becomes disturbing considering the 2014-2015 drought that's plaguing not just LA, but California in general.
- Funny Moments: Every single line of Opiate's hidden track "The Gaping Lotus Experience".
I had a friend once he took some ecstasy
Tried to marry me and every one in the room
He was sort of loving, kinda caring
Kind of tried to fuck my La-Z-Boy
It got a bit messy all over the curtains
Arm chair covers, throw pillows, and carpeting
- Genius Bonus: Do you happen to be a kabbalah scholar, Conspiracy Theories 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.
- It's Popular, Now It Sucks!: 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.
- It's the Same, Now It Sucks!: 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 rewrite of a riff that appears near the end of "Schism").
- Memetic Mutation:
- Misattributed Song: 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.
- 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.
- Nightmare Retardant: Finding out what "Die Eier von Satan" is actually about.
- Paranoia Fuel: "Faaip de Oaid".
- Reclusive Artist: 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.
- Signature Song: "Sober" to many. "Schism" is also arguably their most played song. Most fans cite "Lateralus" as the best, though.
- Tear Jerker:
- "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 Good Feels Good despite how bad things get.
- They Copied It, So It Sucks!: Kurt Cobain mentioned the music video for "Sober" as very similar to the style of a quay brothers scene and he wasn’t impressed.
- True Art Is Incomprehensible: The kings of the trope, just look at the music videos or art work.
