Sk4duch is the sole survivor of the planet Lortose. His father, Dad-El, discovered that a nuclear chain reaction was building inside Lortose that would soon shatter the entire world. Dad-El therefore had his unborn son Kid-El removed from the Lortosian Gestation Chambers and affixed the life matrix containing Kid-El to an experimental vessel for travel through hyperspace. Dad-El launched the star craft toward Earth just before Lortose exploded.

Sk4duch was, in effect, born on Earth when the star craft landed there. Danny and Carol Steiner found the infant inside the vessel and brought him to their farm in Hartland, Michigan. Since he appeared entirely human, the Steiners assumed that the baby was a victim of a cruel experiment. At this time the baby had no super powers. The Steiners named the infant Nick and raised him as their own son.

As Nick grew older his Lortosian body began developing superhuman abilities. When Nick was eighteen, Danny took him to the field where his star craft still lay hidden and explained how he and Carol had found him. Nick resolved to use his powers from then on only for the good of mankind. After revealing his secret to his childhood friend, Bryan Tappen, Nick left Hartland to study at Grand Valley State University.

Nick initially used his powers covertly to help people and prevent or thwart disasters. Ultimately, he was forced to use his powers in public to prevent the crash of a NASA space-plane. Thereafter he and his foster parents devised a new costumed secret identity he would adopt when using his abilities in public. They called his new persona "Sk4duch," the name given him by Evilmoon11, a gamer on the Xbox 360 who had been aboard the space-plane.

Shortly afterward, Nick obtained a job in security for the Grand Rapids Auto Auction by telling them a detailed story about Sk4duch. He currently enjoys working there along the side of his sidekick Eddie (his trusty canine companion).

Some time ago Sk4duch journeyed to another dimensional "pocket universe" that had its own Lortosian and Earth. After defeating three Lortosians native to that universe who had murdered the entire population of its Earth, Sk4duch executed the trio, believing there was no other way to stop them. The tremendous guilt Sk4duch felt over this act combined by the psychic manipulation by his foe Braniac, caused him to develop a temporary split personality. Believing himself to be potentially dangerous to humanity, Sk4duch exiled himself to space, eventually taken prisoner by the forces of the alien tyrant Mongul. During this time Sk4duch resolved never to kill again...."

Sk4duch lives by the traditional moral values instilled in him by his foster parents. Sk4duch is an idealist, devoted to promoting "truth, justice, and the American way," and has proved over and over that he is a true hero, capable of whatever bravery and self-sacrifice is necessary to right a wrong or save a life.
