5 MMA Heavyweights That Would destroy Brock Lesnar in a WWE Ring

#4 Frank Mir

Frank Mir is no stranger to Lesnar.

This list wouldn't be complete without one of MMA's bad boys, which is exactly what you get with Frank Mir. While Mir was suspended back in April for testing positive for Turinabol metabolites, he has repeatedly stated that the tests cannot be accurate, claiming, "I don't know how that's possible, I do not take performance-enhancing drugs."

Frank is no stranger to Brock Lesnar. In fact, the two have gone to war in the cage not once, but twice. In the first meeting, Mir defeated Lesnar at the UFC 81 pay-per-view. However, the results were completely opposite the second time around. At the UFC 100 pay-per-view, Brock Lesnar defeated Frank Mir.

Frank comes in at a chiselled 6'3", weighing 264 pounds. He is a very animated fighter, one who sometimes comes across arrogant. Nonetheless, his charisma would carry over well in the WWE.
