5: Doc Gallows
Gallows has been impressive in the little we’ve seen of him since his WWE debut as part of the Bullet Club offshoot, The Club. His previous stints in WWE as fake Kane, Festus and CM Punk’s associate wasn’t the most successful, but Gallows hit the ground running when he joined NJPW to tag with Machinegun Karl Anderson.
His size and ability made sure he stood out in Japan as he and Karl Anderson ran rough shot through New Japan’s tag team division. He joined the Bullet Club upon his NJPW debut at the 2013 World Tag League, going on to win the tournament along with Karl Anderson before going on to win the IWGP Tag Team Titles at Wrestle Kingdom 8.
Although he went on to achieve great success in the tag team division, he never really managed to cement a place for himself as a singles performer. He improved dramatically during his time in Japan, and has clearly cut down on weight since his first run in WWE. His success along with Anderson prompted WWE to sign the duo in early 2016.
