Mean Character, Nice Actor: The members often have a gangster/thuggish persona, but are actually very down-to-earth and friendly (Zacky Vengeance and Johnny Christ, in particular).
The Pete Best: The band's first three bassists (Matt Wendt, Justin Sane and Dameon Ash) are very often forgotten. Justin did in fact play on Sounding the Seventh Trumpet, but the band didn't gain any mainstream success until Johnny Christ joined the band.
Subverted by Zacky. Avenged Sevenfold were a four-man band on the original release of Sounding the Seventh Trumpet, with Zacky playing lead guitar. Syn wasn't added until the re-release (where he only played in To End the Rapture), although fans tend to assume he was always the band's lead guitarist and Zacky was always the rhythm guitarist.
