#3 Eddie Guerrero
When it comes to shock WWE Championship victories, look no further than Eddie Guerrero. His incredible ascent to finally hold the WWE title came in January 2004, when he won a 15-Man Battle Royale to cement himself as the Number 1 contender.
Brock Lesnar was the man holding the title at the time, and he was every bit as much of the beast he is now, back then. Guerrero was the absolute rank outsider, but in one of the biggest upsets of all time, he shockingly defeated Lesnar at No Way Out to find himself as the WWE Champion heading into WrestleMania 20.

Guerrero pinned Lesnar after delivering a DDT to Lesnar onto the title belt, and then a Frog Splash to send the crowd into a state of pure electricity. The reaction as the ref’s hand striked the mat for the third time was incredible.
That particular event stokes up some highly charged emotions for many, as Guerrero retained his title against Kurt Angle before closing out the show in the ring, celebrating with Chris Benoit, after Benoit had indulged in his own stunning performance to win his first World Heavyweight Championship.
The fact that the image of these two great champions celebrating together in the ring is one that WWE attempts to erase from history, is one that is tragic as much as it is understandable. What can never be erased, however, is the massive impact that Eddie Guerrero had on the wrestling industry, and his against-all-odds WWE Title victory will go a long way towards defining his legacy.
