Early Life
After Rachel divorced Augustine, and Gerald and Jerry elected to stay with their mother, Augustine deemed both of his biological sons "failures", and sought to create the perfect son. Using DNA taken from Gerald's amputated, infected arm, Augustine made a clone of his eldest child, and genetically enhanced him to superhuman levels. The result was Deux.

Mt. Itoi Arc
Deux appears for the climatic battle, where he is again ordered by Augustine to kill Gerald and his friends. Despite Gerald being his Berserker mode, and Fred subjecting Deux to a brutal beatdown with PK Freeze, Deux was able to trump his foes easily. And while Ruby was able to damage him with PK Thunder Omega, it didn't really faze Deux. To protect Ruby, Fred desperately knocks Deux into an iron maiden construct made of ice, but Deux's endurance allowed him to survive being inside it, and he was able to free himself and throw the iron maiden at Fred and Ruby, weakening them both.

Gerald, who was out of his Berserker mode and had gained greater control over his memories, tried to sacrifice to protect his friends from Deux, just as Ruby predicted he would. As a last resort, Fred uses Spectrum on Gerald, temporarily making him invincible. This combined with Gerald's act of selflessness makes Deux have an epiphany about what Augustine told him, and he ultimately refuses to kill Gerald and his friends

Deux's act of disobedience angers Augustine to the point where he disowns him and calls him a "mistake", leaving Deux very heartbroken. Seeing this makes Gerald start heading after Augustine, but Augustine flees through a secret elevator. Fred sympathizes with Deux due to his empathy, and tells him that he understands his situation before giving Deux a hug.

Physical capabilities
Due to being a clone of Gerald and a product of Bush Co., Deux has superhuman strength, endurance, and speed.
