Double is one of the two secondary antagonists from Megaman X4.
Double has two forms that he can shift between.
In his first form, Double slightly resembles an American football player. His pudgy appearance and bumbling façade give him an untimidating cover, but this is merely a cover for his actual agenda.
When he assumes his true form, Double grows to nearly double X's size. His appearance in this form is more threatening, and his eyes turn red and are given green outlines.
Double at first comes across as likeable and good-hearted, but he is really insane and demented. He also had a high charisma, duping his so-called ally Mega Man X into trusting him. He is also shown to be loyal to Sigma, as Double had been willing to pose as a spy within the Maverick Hunters until his boss called upon him.
Double was a spy who worked for Sigma. During the Repliforce Incident, Sigma sends him to spy on Captain Mega Man X's actions. Double disguises himself as a chubby, clumsy worker robot, which easily grants him the trust of X and the other Maverick Hunters. Double then works as X's navigator, always reporting to Sigma on X's progress.
Once X departs for the Repliforce's Final Weapon, Sigma informs Double that his mission is over and to terminate the Hunters. So he destroys the Maverick Hunters who mocked him and goes after X to finish him by himself.
At the Final Weapon, he faces X and challenges him, revealing his true agenda. X was confused by his so-called "friend's" betrayal, but he fights and defeats Double, who mocks X for being so naïve to trust him, exploding shortly after.
In Other Media
Double makes a cameo appearance fighting against Guile from the Street Fighter universe in Archie Mega Man Issue 51. Double was one of numerous Mavericks duplicated by Sigma-1 using the power of the Genesis Portals to form an army to battle Sonic the Hedgehog and Mega Man's team of allies. However, he and his fellow Mavericks were then attacked by the arriving Street Fighters, with Guile giving Double a taste of his Sonic Boom technique (Sonic not being particularly impressed by the ability's name) and finishing him with a Dragon Suplex.
- Double is one of the few Chaotic Evil villains from the Mega Man series, another being the Ra Moon and another being his boss Sigma.
- Double's sword-arm and evil grin upon showing his true nature is similar to that of Shadow from Mega Man X: Command Mission, another double agent/traitor that served with both Mega Man X and Zero later on.
- Double has a short cameo appearance in the opening scene of Mega Man X5 as a flashback of sorts.
