Abe Jenkins was a master mechanic for an aircraft company but grew dissatisfied with his low paying job. Using his considerable knowledge he created a suit that enabled him to lift up to 1 ton on each arm. The armored suit also had suction fingered gloves, wings and a cybernetic helmet to control it all. Abe hoped his new suit would give him the fame he sought. After being defeated by Human Torch and Thing] he was sent to prison.

Upon his release he looked to gain revenge on Human Torch but found only defeat at the hands of Spider-Man. Deciding to forgo his pursuit of fame he decided to focus on gaining wealth. Failing repeatedly he offered his services to Justin Hammer who dispatched him to fight against Iron Man. During the battle his armor was severely damaged and he used all his wealth to repair it with the help of the Thinker. After adding many modifications he hired the Ringer to fight Spider-Man so he could learn his fighting style and add it to his suits system. Defeated by Spider-Man once again he was put back in jail only be released by Egghead. Beetle joined his Masters Of Evil only to be defeated by the Avengers. Abe then created his own team, Sinister Syndicate only to have it collapse due to infighting.

After the "death" of many of Earths heroes at the hands of Onslaught, Baron Heinrich Zemo created the Thunderbolts. Taking the name Mach-1, he grew to like the hero life and along with Songbird sought to leave their villainous past behind them. Baron Zemo revealed that the group were actually former Masters Of Evil members and the public was unwilling to trust them. Abe was convinced to go back to prison by Hawkeye, who had taken over leadership of the group. Upon his release he looks were changed by the Fixer to go with his new identity of Matthew Davis. Abe's new face at first caused some friction with his girlfriend Songbird but she grew used to it. His features eventually returned to normal and he is still working with the Fixer.
