A mysterious young man named "D-boy," driven by resentment towards the alien life forms known as Radam, transforms into the agile and powerful warrior Tekkaman Blade. He hunts down the extraterrestrial enemy with the Tekklancer (variable twin-lances) which provides him with a barrage of diverse, powerful and lightning fast attacks. Coupled with his Voltekka body armor, he is capable of emitting a lethal dose of antimatter particles, sending enemies running for cover.
