Cain Velasquez climbed the beanstalk at UFC 121 and felled the giant atop the heavyweight division, Brock Lesnar.

When he did so, the new Heavyweight Champion might've started a dominant reign over a talented division a la middleweight champ, Anderson Silva. On the other hand, his seismic shift might've triggered a constant rumbling throughout the ranks of the biggest boppers a la Quinton Jackson's dethroning of former light heavyweight king Chuck Liddell.

In the latter case, the belt was on Rampage's waist for one defense against a fading Dan Henderson, then Forrest Griffin kicked it away from Jackson. Griffin got throttled by Rashad Evans in his very next bout, but Suga fared no better—handing the hardware to Lyoto Machida in his first defense.

The Dragon held Mauricio Rua at bay with five shaky rounds to retain the belt for one scrap, but Shogun obliterated him in the rematch to leave no doubt the title would change hands once again.

I mention the travails of the 205-pounders because the current state of the 265-pound division looks increasingly like its littler brother—the deepest class in all of mixed martial arts.

In other words, if Velasquez is able to string together some victories, he'll have accomplished quite a feat. Of course, his performance on Saturday night should convince anyone watching that it's not wise to underestimate Cain—el hombre es muy peligroso.

But the new champ also reminded us that no man or woman is unbeatable. With that in mind, here is the list of the top contenders to Cain Velasquez' shiny new belt:
