“The Machine Gun” Karl Anderson is the long-time tag partner of Doc Gallows in The Good Brothers and one of the founding members of Bullet Club in Japan. He originally broke out in the tag team Bad Intentions in New Japan Pro Wrestling with Giant Bernard (former WWE Superstar Albert/Matt Bloom), where they captured the IWGP Tag Team Championship. Anderson has shown singles prowess as well as being a tag team specialist, winning the NEVER Openweight Championship in NJPW in 2022. But it’s alongside Gallows that Anderson has dominated, winning the IWGP Tag Team titles on three more occasions, as well as winning tag team gold in the WWE (twice) and TNA Wrestling (three times). In 2026, Anderson and Gallows became the inaugural MLP Canadian Tag Team Champions.
