What if Superman Landed in Fallout

A dying world sends its last son toward a peaceful future, but the trajectory fails, and the ship crashes not into Kansas but into the ruins of the Capital Wasteland. Raised in secret by a farmer and his wife, the boy grows into a man of impossible power in a land that has no room for gods. When the Enclave hunts down his origin, he is forced into the open, first as a monster the wasteland fears, then as a reluctant ally of the Brotherhood of Steel, and finally as the Sentinel of a new Commonwealth built in the ashes of Project Purity. Two decades of peace follow, until the war-machine of Caesar and his Legion rolls in from the west, and a traitor inside the Brotherhood arms himself with the one weapon capable of killing a man who cannot otherwise die.
