Abner Ronald Jenkins, also known as the Beetle, MACH-1, MACH-2, MACH-3, MACH-IV, MACH-V, MACH-VII and MACH-X, is a fictional character appearing in American comic books published by Marvel Comics. He made his debut as the Beetle in Strange Tales #123 (August 1964) (where the character was created by Stan Lee and Carl Burgos) and later first appeared as MACH-1 in Incredible Hulk #449 (January 1997) during the Thunderbolts' debut. Jenkins started out as a gifted aircraft mechanic but grew frustrated with his boring, low paying job and created an armor plated, mechanical suit and embarked on a criminal career as the "Beetle". On his first heist he was defeated by Human Torch and Thing from the Fantastic Four. He would later become a regular foe of Spider-Man, often as he worked as a henchman for various criminal organizations. Jenkins later organized his own group of criminals known as the Sinister Syndicate. When a large number of costumed heroes seemingly died in a battle against Onslaught, Helmut Zemo recruited Jenkins and a number of other villains he had worked with in the past to form the Thunderbolts. All members adopted new costumed identities, posing as super heroes to gain access to the technology of the Fantastic Four or the Avengers, groups which had both seemingly perished. Jenkins became known as "Mach-1", using a modified version of his Beetle armor that was designed for faster flight and higher altitude. While the plan was originally to steal technology most of the members decided that they enjoyed the attention and adulation and decided to legitimately become heroes. Jenkins was convinced to give himself over to authorities to serve out an outstanding prison sentence in exchange for the Thunderbolts being granted immunity. During his time in jail Jenkins helped the authorities out, which led to him working for the government after his release from prison. He later began working at the Raft maximum security prison as head of security and worked with the Thunderbolts, who were now a team of criminals who tried to earn time off their sentence by carrying out missions for the government.
