5. Iron Maiden
How many bands can say they have a mutating mascot? Well, Iron Maiden for one. Leaving aside Bruce Dickinson’s vitality and energy, the mere fact that the band created and incorporated Eddie the Head on all their album covers is enough to put them on the list of most theatrical bands. The terrifying Eddie also appears on stage in every Iron Maiden show, and can take on the form of a cyborg, Egyptian mummy, or zombie according to the album theme.
