#1. Karl Anderson and Luke Gallows were released by WWE days after headlining WrestleMania 36
Probably the most obvious, yet vital addition to this list; Karl Anderson and Luke Gallows' release from WWE came as big surprise to the WWE Universe. The Good Brothers were let go by the company just days after headlining Night One of WrestleMania 36 with AJ Styles and The Undertaker.
Anderson and Gallows didn't get off to a proper start in WWE and the company's creative team received heavy criticism for how the treated the former IWGP Tag Team Champions.
After a few rare appearances throughout the course of 2018, Anderson and Gallows were finally reunited with their former Bullet Club stablemate AJ Styles for the second time in WWE. That is exactly when things finally started to fall in place for The Good Brothers.
Having already won the WWE RAW Tag Team Titles on one previous occasion, Anderson and Gallows were on course to help AJ Styles win the WWE United States Title off Ricochet and the duo themselves became two-time RAW Tag Team Champions.
With The OC dripping in gold, it then seemed as if the former Bullet Club trio was destined to do great things in WWE. But that wasn't the case, as after making a cameo appearance in the Boneyard Match at WM 36, Anderson and Gallows were released by WWE within the same month.
