In Universe 1, Baron Blade’s plot to kill the Legacy line at the Wagner Mars Base resulted in failure, because both the current Legacy and his daughter were not present due to previous injuries. But in another, disparate reality, the Baron’s plot was successful, and he slew America’s Newest Legacy. Thus, Iron Legacy was born. He clashed with the heroes of many timelines, always being banished to another universe at the end of the conflict. He eventually wound up back in his original reality, which was shortly destroyed with him in it by La Comodora in order to save Universe 1.
In Universe 1, the Wraith failed to stop Spite from killing her friends Eduardo Lopez and Sarah Scott. But in another, disparate reality, when the serial killer held the Wraith in his grasp and was about to execute her friends, she grabbed one of his superdrug-filled syringes and injected herself with it, giving her the strength to kill Spite before he killed her friends. The Wraith soon after broke into the Pike Industrial laboratories to acquire more of the power-enhancing toxin. Driven by it to be more aggressive than usual, the Wraith went on a killing spree, culminating in the deaths of the Chairman, his Operative, and all of their Underbosses. She then assumed control of The Organization and used it to ruthlessly exterminate anyone who would threaten Rook City. The Wraith’s tyranny was eventually brought to an end, though, by the hero team Dark Watch, aided by Parse, when they killed the Wraith. Yet, years later, when the dread GloomWeaver was hatching another plan to enter the prime material plane, he revived the Wraith in a zombified state, and commanded her to aid his plot. His plan was successful, and he conquered that reality. The Wraith served as his top operative, yet she secretly plotted against him, and with the help of the mystic Zhu Long, she overthrew the Nightmare Walker and ruled the world in his stead.
In Universe 1, the Freedom Five and Omnitron-X defeated the robotic menace of a Cosmically-empowered Omnitron-II with no casualties. But in another, disparate reality, although Omnitron-X did defeat its villainous predecessor, the battle was not without losses. Legacy, Absolute Zero, and the Wraith were slain during the course of the conflict. Wracked with survivor’s guilt Bunker urged Tachyon to help him build something to stop anything like that from happening again. The two remaining members of the FF, along with Tachyon’s sidekick Unity, integrated the Omnitron tech from the recent battle into the Bunker Suit. Donning the newly-upgraded, massive armor, Tyler Vance used its drone-production capabilities to police Megalopolis, pre-emptively quashing any insurrection. Bunker’s former allies attempted to stand up to him, but were imprisoned by him for their “betrayal.”
In Universe 1, an Oblivion Shard crashed near Huntingdon, England. But in another, disparate reality, that same shard crashed near the city of Megalopolis. It was recovered by the heroic Freedom Five, who placed it in secure containment. Tachyon, scientific genius, studied the crystal’s strange emanations, and found that interacting with it would result in unpredictable, and likely destructive, consequences. So the team simply left it in secure storage. Tachyon, though, was tempted by the prospect of studying the strange object, and performed minor experiments in it in secret. Years later, Earth was invaded by Grand Warlord Voss’s gene-bound armada. With Legacy incapacitated and the heroes of Earth seemingly overrun, a desperate Tachyon quickly constructed a device to channel the shard’s power, and used it against the alien horde. It created energy construct-duplicates of Tachyon, which successfully drove the invaders away. But while doing so, the device fused itself permanently with Tachyon. The shard-device also created an energy-storm which ravaged the area, and was slowly growing. After the battle, Tachyon continued to experiment with the shard and the storm. The other members of the FF, however, urged her to stop her experiments before they caused more destruction. But she refused, and so was forced to take them out of the equation, for science.
In Universe 1, the ice man Ryan Frost was revived by Tachyon and later persuaded to join the Freedom Five. But in another, disparate reality, Ryan Frost was reawakened by scientists working at the Barzakh Wing of the Pike Industrial complex. The Chairman quickly but the frozen elemental to work for his criminal empire, by threatening to withhold the cryo-chamber and suit that Frost needed to live. But during one job with the Organization, Absolute Zero and the thugs he was working with were ambushed and defeated by heroes the Wraith and Legacy. Absolute Zero was recovered from the fight and brought to a hastily-constructed cryo-chamber built by Tachyon. He was given an offer by the Freedom Five: either fight crime to pay off his cryo-suit, or spend the rest of his (likely infinite) days in a cryo-chamber. Absolute Zero was fed up with others trying to profit from his unique abilities and condition. He snapped, and attacked the heroes. He unleashed the full might of his elemental power, and plunged the Eastern Seaboard into an eternal winter.
Iron Legacy perished with his universe, but his ideas did not. In his travels throughout the multiverse, he had encountered other “heroes” who had forsaken their restrictive ethical codes in order to more effectively vanquish evil. He brought them together into one team that continued to fight even after its leader’s demise: The Iron Five!
