With a 'F5', Brock Lesnar defeated Kofi Kingston and won the WWE title for the fifth time; however, his joy didn't last long. Cain Velasquez appeared at SmackDown surprisingly to attack him.
After his victory, Lesnar stayed celebrating. At that moment, Rey Mysterio's music played and the masked wrestler appeared, who had been beaten by Lesnar at RAW. But this time, he wasn't alone, as Cain Velasquez accompanied him.

The audience was shocked and shouted with excitement as they saw the UFC fighter walk straight into the ring. Cain Velasquez climbed into the ring, to the surprise of Brock Lesnar. After that, he launched himself and attacked Lesnar with a couple of body blows.
It's worth noting that they had a rivalry not in a WWE ring, but in the UFC octagon. In fact, Cain Velasquez defeated Brock Lesnar by technical knockout and took away the heavyweight title in 2010.
