Serious champ is serious.

UFC Bantamweight Champion Dominick Cruz looks down on his 135-pound title challenger Demetrious Johnson, who will try to be the mightiest mouse in the bantamweight division this Saturday night (Oct. 1) at the Verizon Center in Washington, D.C.

Also in action is heavyweight “Skyscraper” Stefan Struve, who is head and shoulders above the competition (literally) in his fight against Pat Barry.

Their staredown, after the jump.
