5 Best opponents for Brock Lesnar at SummerSlam 

#4 Brock Lesnar vs. Aleister Black

Fade to Brock

Now this one is the least likely to happen due to Aleister Black being the current NXT Champion, but it is not impossible either. Aleister Black is quite possibly the best wrestler in all of NXT at the moment. The winner of the NXT Male Competitor of the Year award is one of the toughest Superstars in recent memory and commands both respect and fear upon his entrance.

I can't see this match happening before Lesnar leaves but at the same time, it is not completely impossible. Aleister could make his way to the main roster sometime before SummerSlam, and I can't imagine a better way to get him over with the casual fans than for him and Brock to have what would be an exciting match full of brawls and kicks, that would see Brock Lesnar, Fade to Black.
