In the 21st century, noted scientist and computer engineer Doc Yoshiyama had succeeded in creating the world's most advanced Artificial Intelligence. He called his creation "C-Life" and managed to make her aware, thinking, and feeling. However, he soon found himself in love with this C-Life girl and wanted to be closer to her, so he digitized and uploaded himself into his computer core, where the two "made love" by combining his DNA and her program core. The end result of their love was the birth of a half-human, half C-Life boy named "Pulseman". Pulseman was unique in that he didn't need to remain inside a computer to survive, and had the power to channel electricity through his body, using it both as a weapon and as a means of quick transport through the power of "Voltteccer".
Unfortunately, living in the computer world for so long twisted Doc Yoshiyama's mind, corrupting his brainwaves and his body. Doc Yoshiyama emerged back into the human world, but twisted and changed into the evil Doc Waruyama. Now, Doc Waruyama establishes the Galaxy Gang, spreading a new wave of cyber-terrorism across the world, and Pulseman must fight his own father and put an end to his gang for the sake of the free world.
