10. Chris Jericho Ruins Edge's Dream Comeback WrestleMania XXVI
After Edge returned and won the 2010 Royal Rumble, he initially held off on announcing whether hed challenge for the WWE Championship or the World Heavyweight Championship at that years WrestleMania. Following former partner Chris Jerichos WHC win at the Elimination Chamber PPV, Edge seized the opportunity to face his one-time cohort at the Showcase of the Immortals. Story-wise, this made perfect sense seeing as how Jericho had regularly mocked Edge on TV after the Rated-R Superstar got injured whilst the pair were still Tag Team Champions. So the stage was set. WWE love a feel-good triumphant return from injury storyline, and so all logic pointed to the only possible result at WrestleMania XXVI being a World Heavyweight Championship win for Edge. Needless to say, it was a major shock to see Jericho emerge victorious at the University of Phoenix Stadium. Not to worry, though, for Edge would get some semblance of justice by spearing Jericho through a barricade after the match and then also attacking him on the post-Mania edition of Smackdown, which led to Jack Swagger cashing in his Money in the Bank briefcase and becoming World Heavyweight Champion.
