#4. The Undertaker's attacker
The Anonymous RAW General Manager may have plagued Monday Nights in 2010, but that same year, there was something lurking on SmackDown. During Father's Day weekend, The Undertaker was found in a vegetative state, leaving him unable to compete for weeks, as fans wondered who did it.
Could it be Rey Mysterio, the most beloved man on SmackDown, or Kane, the tormented brother of the Deadman, that had battled him countless times, and turned on him plenty?
It was Kane.
Despite Kane being the one at first proclaiming he would find the man responsible, his investigation went no-where, with the whodunnit eventually being dropped, as Mysterio just came out and told fans that it was the Big Red Machine all along.
A swerve everyone saw coming, and somehow made even less sense when revealed.
