The Dark Raider comes from a world where Uata the Watcher sent Reed Richards to fetch the Ultimate Nullifier from Galactus' ship instead of the Human Torch. Reed was so fascinated by the various technological devices he found there that he spent too much time investigating them and by the time he returned to Earth Galactus had already devoured the life energy of the planet. Driven mad by his failure, Reed adopted the Dark Raider persona and began a quest to eliminate Reed Richards from all realities, so that the other Reeds would never fail like he did.
