The League Of Justice: Age Of Metahumans

It has been seven years now since unnatural beings commonly known as "Metahumans" appeared out of nowhere and plagued the world with terror, chaos and destruction making it unsafe for human race in general.
Powerful government agencies such as the National Security Agency, the Federal Bureau of Investigation, and Central Intelligence Agency came together with everything they have in their arsenal just to make the world a better place for everyone, but the overwhelming population of metahumans is so great, not to mention they do not possess the weapon powerful enough to neutralize the credible threats.
The government agencies struggled with the devastating rising population of metahumans to the very extent they realized that they have been fighting a war they will never win. At that very moment of devastation, a group of masked metahumans who called themselves "The League Of Justice", came into the limelight to protect mankind from the impending doom by hunting down evil metahumans; therefore starting a feud with the Black Shield, an organization of mad scientists responsible for creating most of the world's metahumans.
The unthinkable actions of the League of Justice didn't just bring the Black Shield into the picture, but also caught the attention of a destructive elite association of metahumans who called themselves " The Elite", whose sole is to deactivate the so-called League of Justice and also wipe out the Black Shield and their army of metahumans once and for all.
