Editing Abner Jenkins (section)

== Fictional character biography ==
Born in [[Baltimore, Maryland]], Abner Jenkins was a master mechanic at an aircraft parts factory who became dissatisfied with his boring, low paying job. Using his considerable mechanical knowledge, Jenkins built an armor-plated, strength-augmenting suit, a pair of wings, suction-fingered gloves, and a [[cybernetics|cybernetic]] control helmet. Calling himself the "[[Beetle (comics)|Beetle]]", Jenkins decided to use his battle-suit for fame, wealth, and adventure, becoming an enemy of Spider-Man.<ref>''[[Strange Tales]]'' #123 (August 1964)</ref> He later joins [[Egghead (Marvel Comics)|Egghead]]'s [[Masters of Evil]] and founds the [[Sinister Syndicate]], a team of mercenaries.<ref>''[[The Avengers (comic book)|The Avengers]]'' #228-229 (February - March 1983)</ref><ref>''[[The Amazing Spider-Man]]'' #280-281 (September - October 1986)</ref>

When most of Earth's heroes, including the Avengers and [[Fantastic Four]], are seemingly killed battling [[Onslaught (Marvel Comics)|Onslaught]], [[Helmut Zemo]] recruits Jenkins and a number of other villains to posing as a superhero team called the [[Thunderbolts (comics)|Thunderbolts]]. Jenkins adopted the guise of "MACH-1".<ref>''[[Thunderbolts (comic book)|Thunderbolts]]'' Annual (August 1997)</ref> However, the Thunderbolts' members begin to enjoy heroism and convert the group into a legitimate team.<ref>''Thunderbolts'' #21-23 (December 1998 - February 1999)</ref><ref>''Deadly Foes of Spider-Man'' #3 (July 1991)</ref>

When the Thunderbolts uncover and thwart a [[Commission on Superhuman Activities]] (CSA) conspiracy to exterminate superhumans, Hawkeye blackmails the CSA into pardoning the Thunderbolts in exchange for the group's silence. CSA agent [[Henry Peter Gyrich]] insists that he will not go along with the deal unless Hawkeye is imprisoned for his [[vigilante]] activities. Hawkeye agrees, despite the protests of his teammates, and surrendered to federal custody.

Most of the rest of the Thunderbolts, including MACH-2 and [[Songbird (character)|Songbird]], are pardoned and released. However, they are forbidden from public use of superhuman powers or costumed identities. MACH-2 and [[Songbird (character)|Songbird]] turn their equipment over to authorities and move to Burton Canyon, [[Colorado]], where Abner Jenkins finds work as a [[tech support]] specialist.<ref>''Thunderbolts'' #50 (May 2001)</ref><ref>''Thunderbolts: Life Sentences'' one-shot (July 2001)</ref>

Later, [[Graviton (comics)|Graviton]] launches his latest attempt at world conquest in Burton Canyon, reshaping Earth in his image. Despite their reluctance to risk their freedom, Jenkins and Songbird join Helmut Zemo in attacking Graviton as part of a new team of Thunderbolts. Graviton is defeated and Earth saved, but MACH-3 and the other Thunderbolts disappear in an explosion created by Graviton's power.<ref>''Thunderbolts'' #59 (February 2002)</ref>
