Pulsar by Mattel

Pulsar action figure Pulsar was a 12" action figure released in about 1977 by Mattel. When the child squeezed a button on the figure's back, Pulsar's circulatory system could be viewed through his clear plastic chest. He also came with a red and black tracksuit. His enemy was Hypnos, a weird purple-skinned alien. The one playset for the character was the Life Systems Center.
