5 biggest "Mystery Attacker" storylines in WWE history

#3 The Great Khali puts down John Cena's challengers

Khali stands tall over Cena

At WrestleMania 23, John Cena defeated Shawn Michaels in the main event of the night, retaining his WWE title in the process. Weeks later, all three top contenders for John Cena's WWE title were found in various backstage areas, in unconscious states. Shawn Michaels, Randy Orton, and Edge were all attacked by a mysterious Superstar.

Cena was later interrupted by none other than The Great Khali, who was revealed as the one who attacked Cena's challengers. Khali went on to challenge Cena for the WWE title, after defeating Shawn Michaels in a #1 contenders match on Raw.

Cena later defeated The Great Khali at Judgment Day by making him submit to the STFU. At the next PPV named One Night Stand, Cena again defeated Khali, handing the giant his first pinfall loss.
