Lionel Jefferies and his brother (Madison), though they were Canadian, joined the American Military. Lionel had the mutant ability to manipulate flesh, bone and other organic components. He used his powers as a medic but went insane during wartime. Madison, who wasn't affected by Lionel's powers, captured him and placed him in psychiatric care.
He remained there until Heather Hudson discovered him and accidentally freed him. He repaid her by physically converting into a rather monstrous appearance. Alpha Flight finally caught up to Heather and Madison was finally able to get Lionel to turn his powers against himself, apparently healing his psychiatric trauma.
Lionel went on to form the New Life Clinic with backing from unknown sponsors. There he began to acquire a patient base of various super-humans. He became an ally of Alpha Flight often using his powers to aid in medical matters. When Roger Bochs was diagnosed with the Bends, he was placed in Dr Jeffries care. During his recuperation, Jeffries gave Bochs new legs and a younger, fitter body.
Alpha Flight soon discovered that Jeffries was not cursed of his insanity when it was discovered that Bochs' legs were created using dead tissue. Jeffries' own insanity seemed to spread to Bochs as well. After returning Bochs to Jeffries care, they discover his insanity. Jeffries and Bochs merged to become Omega, capable of changing his own physical form. He mutates his brother to prevent him from stopping them.
Omega battles Alpha Flight and begins to absorb them. When Bochs had a change of heart, Jeffries lobotomized him. Kara took control of Omega and forced him to restore Madison. Madison merged with the Box armour and decided the only way to stop Omega was to kill him.
