The Aquabats! Super Show! 1x13

Down on their luck and out of money, The Aquabats try to find an opportunity to re-establish their superhero status in order to help sell their surplus of merchandise. When an impending alien invasion masterminded by the diabolical Space Monster "M" defeats the city's other, far more competent superhero teams, it's up to The Aquabats alone to summon their collective strengths and stop him before he destroys the planet.
