Apocalypse orphan

Commander Orlando Iron Wolf is aboard the International Space Station when a blinking light on his computer console alerts him of a fast-moving comet headed for a collision with planet Earth. With no way to stop the impending doomsday, the world descends into anarchy. Massive transport ships are built to colonize the moon, and evacuation of a chosen few begins. After a shuttle mission to study the approaching comet goes awry, Wolf is forced into cryogenic sleep, and the onboard computer assumes control of the ship. Wolf awakens 50,000 years later to a wildly different earth. Endowed with incredible strength, he finds himself caught in a war between primitive tribes, and his survival depends on Syn, an advanced computer intellience who has fallen in love with him.
