What exactly were Pulsar’s powers?

When I first saw the commercial for Mattel’s Pulsar, I admit I wanted one, but even then, I wondered what exactly was the advantage to having a see through chest.
Was it a good for fighting crime, did bank robbers drop their guns in order to vomit? Pulsar’s enemy was named Hypnos and is pictured above, he had the same issues as Pulsar, but he’s not as gross. There is a backstory here that the world needs to know, how come we have erotic stories for Chip and Dale’s Rescue Rangers but not a decent Pulsar origin story? H/T>
