4. Brock Lesnar
One of the most physically intimidating superstars in the WWE, Brock Lesnar has done it all in the WWE. Winning championships and destroying superstars was always Lesnar's motto, and he has successfully completed both of those missions. Now, Lesnar has nothing else to do - except facing the Deadman, the Undertaker. Brock Lesnar is a dominating beast who isn't scared of any competition. After returning to the WWE in 2012, Lesnar has defeated every single challenge he had in front of him - except John Cena. John Cena and Brock Lesnar might have a feud later on, but the feud everyone craves for is Lesnar facing the Undertaker. Undertaker and Lesnar have no history, and it would be interesting to see two monsters collide. Brock Lesnar could easily end the Streak, but that depends on the WWE, however, if we get to see the Lesnar/Taker match at WrestleMania XXX, the event would be excellent.
