Chronicled in both live-action and animated segments, The Aquabats! Super Show! is centered around the adventures of The Aquabats, a group of superhero rock musicians who travel the countryside on a self-appointed mission to fight evil and "destroy boredom", protecting the world from the villains and creatures who threaten to destroy it while aiming to become a famous rock and roll band in their own right.  The Aquabats consist of singer The MC Bat Commander (Christian Jacobs), the swaggering leader of the group; bassist Crash McLarson (Chad Larson), who can grow up to 100 feet in size; drummer Ricky Fitness (Richard Falomir), who has the power of super speed; guitarist EagleBones Falconhawk (Ian Fowles), who's armed with a laser-shooting electric guitar; and keyboardist Jimmy the Robot (James R. Briggs, Jr.), an android. Despite their superhuman strengths and abilities, The Aquabats are quite bumbling, disorganized, and sometimes cowardly when faced with danger; this has in fact led them to be labeled "the world's most inept superheroes". The band lives and travels by way of their "Battletram", a modified recreational vehicle which, despite its small exterior, has an implausibly massive interior (similar to the TARDIS from Doctor Who or The Big Bologna from The Kids From C.A.P.E.R.), which contains, among many things, a science lab, a command center, and a living room.  The Aquabats' origin story was left intentionally vague throughout the series, a choice Jacobs explains was done for the sake of the viewer's imagination, as kids are more accepting of the inherent absurdity of the premise than adults tend to be: "'There's five guys. This is what each of the five guys does. There are monsters. They're gonna try to fight them'. It's so simple. And I think that's why it's so awesome with kids--they just take it and run with it". In the first five episodes of season two, each member of The Aquabats shares their memory of how they joined the band via animated flashback sequences; however, all of these flashbacks directly and intentionally contradict each other, leaving it unknown which--if any--could be considered officially canonical.
