Edward Pasternak was first seen being hired by former Secret Empire employee turned geneticist Carl Maddicks to capture the Beast, then a member of X-Factor, so that Maddicks could experiment on McCoy to learn of a means to reverse genetic mutation in order to turn his son Artie back to a human. Hank's friends would learn and Marvel Girl would offer Tower a place with X-Factor. Tower would laugh at this offer and walk away. Tower would join with the Alliance of Evil, a group of mutants under the employ of Apocalypse
Apocalypse would utilize Nowlan to boost the powers of his minions, including Tower, a process that would make Tower and the others addicted to Mike's power boosting capabilities. Mike noted that wherever X-Factor went, the X-Terminators were never far behind, being the first to come close to the fact that both teams were the same.
The members of the Institute would part company, and some years later Tower would be murdered by the hunter known as the X-Cutioner. Sometime later, Tower would be one of the many mutants resurrected by for Selene by Eli Bard using the Transmode Virus. He would be part of Selenes attack force on Utopia. When Selene was ultimately destroyed by Warpath, her death eliminated the Transmode Virus from the mutants she had resurrected, Tower's ultimate fate remains unrevealed.
