Former Bullet Club members Luke Gallows and Karl Anderson debut on 'RAW'

After months of speculation and rampant teases (most of them from the parties involved), Doc Gallows (now renamed Luke Gallows) and Karl Anderson finally made their main roster WWE debut on Monday night during RAW.

They appeared out of nowhere following a first-round match in the No. 1 tag team contender tournament. After the Usos picked up a victory over the Social Outcasts to advance to the semifinals, Gallows and Anderson beat them down both inside and outside of the ring until they were sent packing by security.

Anderson and Gallows were two of the most well-known members of the massively popular Bullet Club stable in New Japan Pro Wrestling. WWE social media (and Gallows and Anderson) did not shy away from the Bullet Club references.

Both Anderson and Gallows had given their notice to New Japan on Jan. 4, the same day as the promotion's massive Wrestle Kingdom 10 event. That was also the day that Shinsuke Nakamura gave his notice to New Japan. Nakamura, of course, debuted on Friday night's NXT TakeOver: Dallas live special.

This is the first time the 36-year-old Anderson has ever been signed by the WWE. He is a former NWA tag champ and a four-time IWGP Tag Team Champion. Gallows was with the company from 2005 to 2010, first in developmental, then most notably as Festus and later Luke Gallows, part of CM Punk's now-legendary Straight Edge Society. He held the tag titles in New Japan three times with Anderson.
