Earth's first and best line of defence is its heroes. For generations, brave men and women have answered the call to protect the world from the villains who threaten its safety and security, and that threat is real. Today, organizations such as VIPER, ARGENT and PSI use both superpowers and super technology in their dastardly plots to control the world. In addition, creatures from outer space and other dimensions seek to enslave humanity and super scientist Teleios is creating an army of clones and super powered constructs to do his bidding. But the greatest threat of all is Doctor Destroyer. A superhuman genius driven to conquer, Destroyer will not stop until all of humanity bends knee to his greatness. In 1992, Destroyer obliterated the city of Detroit and killed thousands. With years to prepare, his next attack is sure to put the entire planet in peril. But humanity does not stand alone.

Led by The Champions, protectors of Millennium City, the world's heroes have launched a crusade for peace, security and justice. But they need allies. Defender is calling for a new generation of superheroes to fight in a war against evil that spans the globe - and beyond. Will you be one of those heroes? Save the world and be a champion.
