Zetman

ゼットマン

Jin Kanzaki was engineered by the Amagi Corporation as the ultimate weapon to destroy the Players, shape-shifting creatures that escaped the company's labs, but was smuggled out to be raised as an ordinary human. Kouga Amagi, the corporation founder's grandson, builds powered armor to fight as the hero Alphas out of his own sense of justice. As Jin's ability to transform into the monstrous ZET surfaces, the two are drawn into the same war from opposite sides.
