Dwight Hubbard, much like the name sake he would adopt with Genetech, was an impulsive person, often acting before thinking. As a gang banger, Dwight made a name for himself, before Genetech took him in and experimented on him, turning him into Impulse. As Impulse, he had enhanced strength, agility, endurance and super human speed. The armor he was equipped with also had blades that were tainted with a powerful toxin that could instantly paralyze and render people unconscious. Impulse was one of the original members of Psionex, and as such, had several encounters fighting the New Warriors.
When the New Warriors fought against Terrax, only Mathemanic and Impulse remained from Psionex to help the New Warriors. Mathemanic was put into a coma when Terrax shifted the earth and buried Mathemanic under stone. Terrax also, with a swift strike, snapped Impulse’s back. Mathemanic eventually awoke from his coma, but Impulse remained bound in the wheel chair.
