- Large Ham: As over-the-top and hammy as you would expect from Jack Black Adam Westing.
- Mad Artist: Jacks ideas of finding ways of finding inspiration and rhythms for his songs come across as rather eccentric to say the least. Methods include: banging holes in the ceiling, subjecting himself (and Kyle) to freezing in his fridge and overheating via a steaming kettle, purifying their insides by swallowing an incredibly long string to purify (their) insides, drawing a pentagram on the floor with mustard and ketchup and drawing energy from it, and, most famously, breaking into the Rock and Roll History museum to steal the Pick of Destiny to harness its power.
- Rage Against the Mentor: When KB is ousted as a fake, JB is rightfully pissed.
- Scatting: Does this a lot when singing.
- Small Name, Big Ego: Jack is very enthusiastic in Tenacious Ds rocking abilities, often inflating how awesome he and Kyle are as rock stars and will go to any lengths to make sure that the rest of the world realizes this. Whenever a situation deflates this confidence (like Kyle ceasing to cooperate in writing a song or when the Open Mic host says that they need to write better songs), he usually lashes out in frustration and takes huge leaps to try and fix it.
- Three Chords and the Truth: Jack pretty much plays simple power chords on guitar.

He claims that he did this because loved her, but he only found out about her the night before when Jack told him with he confessed his feelings over her to him and has only actually interacted with her for a literal minute. Even if they have the same type or whatever, that is seriously a dick move to do to your best (lets face it, only) friend.
- Mentor Archetype: In the first act of the film, Kyle acts as such to Jack. While at first dismissive of him, he takes Jack under his wing after saving him from a group of hooligans where he takes him under his wing. There he teaches him various rocking tools like the power slide and cock push-ups which actually helps them both later in the film. After he is found out as a fake, he fills into the quiet Straight Man role he is associated with.
- Mistaken for Badass: When Jack first meets him, he is blown away by Kyles guitarist skills and begs him to take him under his wing. He takes the credit for saving him from a group of hooligans and convinces Jack that he is a famous pro that has worked with the greats.

A writer that moves next door to Jack and Kyle in The Greatest Song in the World.

When Jack and Kyle get a look at the website he made for them, they end up turning into his psycho-fans instead. By the time he comes home from work the next day, they leave him literal dozens of messages on his voice box, message all the hospitals in the tri-state area when he does not call back, somehow learns various personal details of him and break into his apartment window despite the door being unlocked with him there.
- Retcon: In the series, Lee first meets Jack and Kyle while the band was already formed and performing, having made a website of them on his own time. In the movie however, Lee first meets them when JB and KG first met by chance.
- Stalking Is Love: Of the platonic variety. By the end of the band's Obsession Song about him, Lee admits that while it does scare him, he has never had anyone who cared so much about him, and the episode ends with Lee singing with them on stage about their friendship.
A Cult found in the middle of the desert where Tenacious D are driving in.
- Cult: A rare, non-sinister example. The followers are all Christian hippies that believe that one parts with a piece of their souls when they defecate, and that they bury their deceased bodies with all of their feces for their souls to be whole. Their leader Liggaguie admits that they are a cult and they spend time through singing and talent-shows. While generally peaceful and probably not the kind to brainwash, they do keep guns around and board up their doors when ask to leave by the County Health Department.
- Green Thumb: Because they keep the "collective leavings" of their members as part of their philosophy, their soil is very fertile, demonstrated with a potato the size of a human torso.

- Casting Gag: To an extent, as Dave Grohl is famously known as one of the nicest people in the music business.
- Cluster F-Bomb: He only appears in the climax of the film and he swears just about as much as JB does throughout the whole film.
