Space☆Dandy 2nd Season

Synopsis

Johnny, the Commander-in-Chief of the Jaicro Empire's armed forces, keeps sneaking off from his responsibilities to play guitar and chase his dream of becoming a rock star. After getting into a fight with Dandy at a bar, the two men end up forming a band called "the Dropkix"; Dandy is the singer, Johnny is the guitarist, Meow is the bassist, and QT is the drummer. Next, Johnny waits for inspiration to strike for the band's hit song while QT and Meow decide to actually practice. Dandy manages to get the Dropkix their first gig at a dive bar with only three aliens watching (including the janitor), but their popularity skyrockets when video of Dandy fighting the audience during the show goes viral. The band is quickly signed by an agent and sent to Space Budokan for their big live show, when Johnny has to duck out to lead a Jaicro assault on a possible Gogol weapons platform. At the last second, Johnny reverses his decision and crashes through the roof of the arena with his mech. His army is unsure of what to make of it as the Dropkix play their first (and last) show ever, but Johnny's actions indirectly lead to a cessation of hostilities between the two empires.
