to have a single super-power in his different lives, indicating this is the reason he exhibits superhuman abilities while no other tektite test subject does. Before they part ways, the Phantom Stranger warns Mitch that his life has a great purpose and reminds him that in many lives he has been an enemy to the immortal villain Vandal Savage. The villain Skism causes reality to warp around Mitch, outfitting him in a superhero costume and temporarily convincing him he is a masked hero. Mitch then formally meets Superman, who has met a future version of the Resurrection Man in the 853rd century (during the crossover DC One Million) and invites him to join the Justice League. Working with the team for a short time, Shelley decides a superhero life is overwhelming and not right for him, then leaves with Batman's blessing. Mitch later teams up with the Forgotten Heroes, a team originally formed by the heroic Immortal Man to fight his arch-enemy Vandal Savage. Before recorded history, Savage and his longtime enemy the Immortal Man gained their forms of immortality via exposure to a seemingly radioactive meteorite. This made Savage ageless and nearly invincible to injury, while the Immortal Man was able to die but each time would instantly reappear elsewhere on Earth in a new body and with his full memories intact. Cave Carson of the Forgotten Heroes explains to Shelley that the meteorite exposed the two men to tektites of unknown (possibly alien) origin, causing their immortal abilities. Savage then funded the Lab, hoping DeWitt (his son) and the other scientists could replicate the tektites in his own body. These replicated tektites were then injected into Shelley, giving him his resurrection power and slowly undoing the brain-damage he suffered from the gas main explosion, restoring his memories. Cave Carson initially believes that Shelley is actually Immortal Man, who was believed to have finally died during the Crisis on Infinite Earths and hasn't been seen since. Later, Savage confirms that the Resurrection Man and the Immortal Man are separate people, and reveals that the Immortal Man has been his prisoner for years. Shelley, Savage, the Immortal Man, and the Forgotten Heroes then join forces against a creature that emerges along with a second tektite meteorite. This creature, a "Warp Child", alters time and reality. To save the day, the Immortal Man melds his tektite field with the creature's own,
