As believable as they come, fans find it easy to buy into the fact that Lesnar is a fighting machine, probably because he's been there and done it, capturing the UFC Heavyweight Title in the process. After 'The Beast Incarnate' had been first placed against John Cena, Lesnar needed another feud which would reflect his top star status. Enter Triple H, who had a fittingly war-like series of matches opposite Brock. Not all of them were terrifically well-received by critics, but generally, the pair worked well together. The entire atmosphere of the rivalry would have changed if somebody like Justin Bieber had become involved. The mere thought of the pop prince standing mid-ring, frozen in fear at the chaos ensuing around him is pretty funny, but by some miracle, we haven't yet been subjected to Bieber fever in WWE. With that in mind, there's a lot of people who would plunk down 9.99 to see Brock Lesnar hit Justin Bieber with an F5.
