- Awesome Music
- Broken Base: Just about every Leppard fan loves Pyromania, but other than that they're split between people who prefer what came before it and people who like what came after it.
- Chorus-Only Song: "Pour Some Sugar on Me".
- Crowning Moment of Heartwarming: The band never considered replacing the drummer.
- Crowning Moment of Awesome: Rick Allen's comeback concert at Donnington Music Festival.
- Think Rick can't do drum solos anymore thanks to his missing arm? THINK AGAIN.
- Earn Your Happy Ending: In contrast to Steve Clark, Pete Willis quit drinking after he was fired from Def Leppard. He said he drank originally as a crutch because he couldn't handle the pressure of the band's sudden fame, and found his firing to be something of a relief in hindsight. He's since retired from music and runs his own successful property-management business.
- Epic Riff: Many.
- Face of the Band: Joe Elliott is the face, and Phil Collen is known for appearing with him in most interviews. Rick Allen is recognised for obvious reasons.
- Fanon Discontinuity: Slang. The band even started phasing out songs during the supporting tour for the album once they realized fans weren't into them.
- Genius Bonus: One scene of Hysteria: The Def Leppard Story shows Phil and Steve arriving at a video shoot riding a two-seated bicycle. This mirrors an anecdote they tell about renting a two-seater and riding it to a concert sound check.
- The same scene invokes their nickname "The Terror Twins." Oddly, this more well-known bit of trivia is only mentioned the one time.
- Germans Love David Hasselhoff: They concentrated their early efforts on breaking into the American market and did well there with Pyromania and "Photograph". They didn't have a proper hit in their home country until "Animal" was released a full decade after they formed and Hysteria became a huge seller. This prompted some less clued in critics to assume they were American "Bon Jovi rip-offs". "Another Hit and Run" was written as a response to people in the U.K. constantly criticizing them for nonsensical reasons(to the point of pelting the band with objects during the Reading Festival)
- Growing the Beard: Pyromania is regarded as the album where the band's songwriting, sound and style came together completely.
- "Holy Shit!" Quotient: Pete Willis. How much do you have to drink to get kicked out of Def Leppard?
- Protection from Editors: They actually became pretty irritated by this trend during Jim Steinman's brief tenure as producer for Hysteria - they were used to Mutt Lange getting them to do endless takes of a song and then tirelessly edit them into a finished product, whereas Steinman was happy to use takes in which the band hadn't even tuned their guitars because it "sounded honest".
- Since then, the band has been happy to mention that Jim Steinman was famous for being a great songwriter, not a great producer.
- Signature Song: "Pour Some Sugar On Me" and "Rock of Ages".
- Uncanny Valley: The CGI in "Let's Get Rocked" hasn't really aged well.
