Tropes which apply to everyone
Cool Plane: They go on tours in a customized Boeing 757 called "Ed Force One", piloted by Bruce Dickinson himself (who works as a commercial pilot between rocking).
Digital Piracy Is Okay: The band couldn't give less of a flying rat's behind if you downloaded their music. In fact, they encourage downloading of their music, and have even gone so far as to state "We're not like Metallica".
In an interview with Steve Harris, when asked about bootlegs
"I have some... I collect them."
The band also asked fans attending the first leg of Somewhere Back in Time to send over any video footage they took during the concerts, as they were hoping to include it in their documentary Flight 666.
In the Give me Ed 'Til I'm Dead Tour, Bruce said this once:
"... if you wanna record this song and you wanna put it on a world wide web - on the internet, so all your friends could listen to it - as long as you buy the album in September - we don't give a fuck my friends!"
Distaff Counterpart: The all-female, California-based tribute band The Iron Maidens. Special mention should go to the lead singer, Bruce Chickinson. Rather than being just a novelty act, all of the members of the Iron Maidens are accomplished musicians who do such a good job covering Maiden's songs that they've received praise from the group itself.
Arguably, the true Face of the Band. He started as a creation of Derek Riggs for a punk band, which got rejected. Harris then picked him up, and the rest is history. Eddie has been part of the band since their very beginnings.
Take That: In the cover of Sanctuary he's seen murdering Margaret Thatcher (who eventually returns to stalk him on the cover of Women In Uniform for revenge). He's also used a bit more lightheartedly when a band member departs, such as Paul Di'Anno and Bruce (though the latter came back).
Arguably Iron Maiden's most well-known member, Bruce Dickinson sung in several bands before singing in Samson, band which was part of the New Wave Of British Heavy Metal in the early eighties. In 1982, after Paul Di'Anno left the band, he was hired as the new singer. That same year, "The Number Of The Beast" came out, and the rest is known history. He has also a solo career, which comprises albums of Hard Rock, (Tattooed Millionaire) Grunge (Skunkworks) and Heavy Metal. (Accident of Birth, The Chemical Wedding and Tyranny Of Souls)
One of Maiden's main composers, Adrian joined the band in 1981, coming from Urchin. He was responsible for many of Maiden's biggest hits, and the band took a big hit in 1990 with his departure. He then had some Hard Rock projects (A.S.A.P., Psycho Motel) and played with Bruce Dickinson in two of his solo albums (Accident Of Birth and The Chemical Wedding) before coming back to Maiden in 1999, along with Bruce.
He started in The Eighties playing in a band called White Spirit. Then, he played with several musicians such as Fish, Ian Gillan and groups and projects such as Gogmagog (where he played with Clive Burr and Paul Di'Anno, former members of Iron Maiden) and Bruce Dickinson's first solo album. It was in fact thanks to Bruce that he was hired for Iron Maiden, as replacement for the then exiting Adrian Smith. He never left the band since then, even when Adrian Smith came back in 1999.
Aerith and Bob: Inverted: Paul, Adrian, Dave, Michael, Steve... and Janick.
Berserk Button: Do not suggest that Iron Maiden was influenced in any way, shape, or form by punk rock when Steve Harris is around.
Creator Breakdown: The X Factor was an album Darker and Edgier than even Fear of the Dark. A lot of it comes from Steve Harris's divorce and his dad passing away. "Blood Brothers", from Brave New World is said to be about said death.
Not Christian Rock: He said he's not religious, even if many songs deal with spirituality. But the band is far from being Satanist.
Record Producer: After Martin Birch's retirement, he took part of the producing duties since The X Factor.
Step Up to the Microphone: Immediately before Maiden's second ever gig, Paul Di'Anno was arrested outside the club they were due to perform in for carrying a concealed switchblade. Ron Smallwood, their prospective manager, ended up ordering Steve to sing on the basis that he was the only one who knew all of the lyrics.
Garfunkel: He can be seen as this, considering that all the other 5 members are prolific composers but he has only written one album track. But he compensates by being one of the best drummers in the business.
Biography: Di'Anno has written an autobiography, titled The Beast. The book is full of his rock star exploits, namely getting drunk, banging groupies, and beating people up.
Berserk Button: Di'Anno is known for starting fights with people who anger him, as mentioned in his book The Beast. Also evidenced with an infamous show in Ukraine where Paul was going to beat up a fan who suggested that Bruce Dickinson was a better singer than him (even though Paul made a similar statement in the early days).
Name's the Same: He shares his "Paul" name with PaulDay, and Paul Bruce Dickinson, both former and current vocalists of Maiden.
Stage Names: He's got Italian and Brazilian parentage, and thus created a surname that reflected the former heritage.
Start My Own: He went on many solo projects as well. (Battlezone, Killers and the band Di'Anno) Sadly subverted in that the majority of Di'Anno's solo career is spent playing old Maiden songs, either live, re-recording them for "best of" compilations, or appearing on Iron Maiden tribute albums.
