Throughout their career The Aquabats have maintained a fictitious backstory which purports them to be superheroes from a distant island called Aquabania. The band's costumes and pseudonyms tie into this mythology, which is detailed in the liner notes of their albums. Over the years the story of their origins has evolved, changed, and occasionally been reconnected to explain changes in the band's lineup. They have also built up a roster of allies and enemies, many of whom are featured in their album artwork and often appear onstage with them as costumed characters in choreographed fight scenes.
