Early Life

Brendan Doyle was a high priced mercenary from Scotland.[2]

Cordco, Inc.

He was hired by Edwin Cord, an industrialist whose company made the Mauler battle-suit but was imprisoned for his immoral business dealings. Doyle was hired to steal the Mauler suit from Stark International, where the battle-suit had been stored after Cord's business was bought by the company.[2]


Doyle, however, promptly left Cord's employ, and began a life of crime as a super-powered mercenary. He went up against Spider-Man[3] and Wonder Man.[1]

Armor Wars

However, Tony Stark realized that some of the circuits in the Mauler armor (among other armors) utilized principles stolen from the Iron Man Armor. Stark, as Iron Man, began a crusade to neutralize the technology that had been stolen from him. When confronted by Iron Man, Doyle realized that he could not succeed in stopping Iron Man, and surrendered the Mauler suit without a fight.[4]


At a certain point, he was employed like a mercenary by unidentified employers for to kidnap Vindicator in Canada. However, she manage to neutralize him, menacing him to don't return in Canada.[5]

Civil War

During the superhero Civil War; he was recruited into Hammerhead's criminal army to take advantage of the Superhuman Registration Act. Iron Man and a number of S.H.I.E.L.D. Agents raided their meeting and they were all arrested.[6][7]

The Mandarin

Years later, Mauler was used by Mandarin in an army of Iron Man villains to take down the armored Avenger.[8]


At some point in time, Brendon had a son named Danny. Danny's mother abandoned him, and Brendon was denied of custody due to his criminal past. Brendon let him go and understandably so, because he believed Danny would be safer without him.

However, Danny died at age five in a bus collision. Brendon had a breakdown, feeling that he had failed the boy. Distraught, he went into a fugue state and travelled to Danny's town of residence, Rosemont, California. Brendon came across Bobby Morris, a child that resembled Danny, and kidnapped him in order to raise him the way he couldn't raise Danny. Brendon immediately drove away, but, on the outskirts of the Rosemont, he was intercepted by Hyperion, who managed to get Brendon to snap out of it and surrender to authorities.[9]
