The Justice Brigade

Four teens from different places live double lives as a superhero team that protects the world from evil at any time and location. Working together and using state-of-the-art crime-fighting technology, their superpowers, and their martial arts skills to help them, they think they can beat any evil guy or problem that comes their way. They also use their smarts to figure out how to stop their bad guys before they get away with whatever they're after. And if they see or hear any trouble, they immediately try to stop it, with or without their teammates.
