5 Seconds of Summer Morph Into Superheroes in 'Don't Stop' Video: Watch

Summer is the time for superhero movies to hit the multiplex, and on Sunday (May 18) -- two weeks after "The Amazing Spider-Man 2's" opening, and a few days before "X-Men: Days of Future Past" -- the guys of 5 Seconds of Summer donned the tights and capes for the music video to their next single, "Don't Stop."

After practicing some moves in their bedrooms, the 5SOS boys find the courage to venture out into the unknown… and save a missing cat. But wait! There's also some ninja badassery, a roundhouse kick from Calum, and Luke simply has to point his finger to knock a bad guy down. Perhaps he's the one with the true crime-fighting gift!

5 Seconds of Summer rocked the 2014 Billboard Music Awards on Sunday night (May 18), performing their breakout hit "She Looks So Perfect" and making their network television debut. The group's "She Looks So Perfect" EP debuted at No. 2 on the Billboard 200 chart last month, officially announcing the arrival of the Australian group.
