Kevin Owens
While some fans might argue that John Cena did end up going over Owens in the end, the fact that Owens defeated John Cena, clean, on his PPV debut is part of the reason that Owens is the star he is today.
Cena was in the middle of his US title open challenge run at this point and his feud with Owens was no doubt the high point of that excellent run. Owens and Cena tore the house down at the Money in the Bank PPV, and Owens, the then WWE champion ended up looking like a star when he pinned Cena clean in the middle of the ring.
