#1: Triple H's quad tear skips Invasion
The Invasion storyline is remembered for many reasons, and the most of them aren't good.
The attempted coup by WCW and ECW to destroy the WWF, the storyline took up the majority of 2001, and led to some questionable booking for all sides.
One Superstar who was able to skip it though, was Triple H.
During a tag team match on RAW, The Game suffered his first quad tear, but somehow continued the match, at one point even being placed in the Walls of Jericho.
After missing the entire Invasion (which, spoilers: WWE won!), the Cerebral Assassin returned to the company in January 2002 as a face.
Winning the Royal Rumble, the Game would cement his return by winning the Undisputed Championship from Chris Jericho at WrestleMania X8.
