5 biggest "Mystery Attacker" storylines in WWE history

#2 Triple H turns on Shawn Michaels

Triple H

After WrestleMania 18 was done and dusted with, Shawn Michaels returned to WWE. Soon after, he aligned with Triple H and convinced him to choose Monday Night Raw over SmackDown. The Game agreed and the two reformed D-Generation X. On an episode of Raw, the duo came out sporting DX gear. Just when the two were about to perform their signature DX taunt, Triple H hit a Pedigree on Michaels.

Michaels was mysteriously attacked later in a parking lot, and his head was put through a car window. A segment on Raw saw Michaels showing a CCTV footage from the night he was attacked, revealing that the mystery attacker was Triple H. The Game thus turned heel on his best friend and the two Superstars went on to have a "Non-sanctioned Match" at SummerSlam, which Michaels won.
