#3 The Ruthless Aggression Era (2002-2008): Edge
These two guys were just too hard to choose between. Both Randy Orton and Edge were two heels who were head and shoulders above the rest during the Ruthless Aggression era, but compared to each other, I think they were neck and neck.
However, as I am a person who does not like to give an indecisive answer, I will go with Edge as my choice as the Ruthless Aggression Era's best heel.
When Edge was paired with his then real-life girlfriend Lita after winning the first ever Money in the Bank briefcase at WrestleMania 21, the man set off on a heel run that no one will forget anytime soon. When Edge's relationship with Lita became public, it gained him a lot hatred from fans, because he had an affair with her whilst she was in a relationship with his friend and fellow WWE Superstar, Matt Hardy.
Despite many wrestlers in the locker room losing their respect for Edge, this was the greatest thing to ever happen to him, because it helped him find his dark side. Edge became this crazy, obsessive, brutal heel, and when WWE used the real-life beef between him and Hardy as a storyline, and Vince McMahon knew he had struck gold.
The "Rated-R Superstar" really came into a world of his own, especially after venom-filled matches with Matt, and he was great at shoving his victories both in bed and in the ring in the faces of fans.
Edge truly solidified himself as the company's top heel when he cashed in his Money in the Bank contract on a battered and bloodied John Cena at the New Year's Revolution PPV 2006, with the on-screen backing of Vince McMahon. The Edge and John Cena feud that ensued after this was my favourite John Cena feud of all time, and many would agree with me,
Their back and forth exchanges throughout 2006, before and after WrestleMania 22, were extremely intriguing and entertaining, with Edge's twisted and evil ways playing a big part in the success of the rivalry.
In 2007, Edge got the Money in the Bank briefcase again (this time by winning it off that year's Mr. Money in the Bank, Mr.Kennedy, in a singles match), and this led to one of the other great Edge feuds, as Edge left Raw for SmackDown and cashed in his Money in the Bank contract on The Undertaker, defeating him for the World Heavyweight Title.
This led to these two feuding with each other for the next year or so (2007-2008), with Edge trying to cheat every possible way in order to retain his title.
During that year-long rivalry, Undertaker did manage to win it from the "Ultimate Opportunist" in the main event at Wrestlemania 24, in what was a match considered to be "The Deadman's" best WrestleMania match up to that point.
Edge's heel skills would continue to shine brightly until the very end of the Ruthless Aggression Era in mid-2008, with other feuds involving Jeff Hardy, Big Show, Batista and Rey Mysterio. He then turned face after returning from an injury in 2010, before his eventual forced retirement due to injury in 2011.
Edge's heel run throughout the Ruthless Aggression Era in WWE was a piece of art that will be hard to ever emulate. Edge was inducted into the Hall of Fame in 2012, and deservedly so.
