Shlemenko is known for his unorthodox striking style, which is difficult to refer to as traditional Muay Thai , Kickboxing , or ARB . Alexander is known for his knee strikes, he also often uses techniques such as the spinning backkick or spinning backfist. As stated in many interviews, he prefers to fight stand-up rather than on the ground, always trying to knock his opponent out. Often esteemed as a pure striker, Shlemenko also has some grappling skills, which he showed by defeating via submission among others Gregory Babene and Zakir Lalashov   (both via triangle choke). Alexander switches from southpaw to orthodox during his fights. In his blog he says, that he can fight equally in both positions. 
The whole situation was kind of sketchy because they waited until the very last minute to announced Brock’s return, which helped him avoid a usually-mandatory 4 month testing period. It wasn’t enough, though, because he still tested positive before the competition took place (But the results weren’t revealed until after the fight), and also failed another test that took place on the night of the fight. His opponent, Mark Hunt, was rightfully upset – he was the one getting smashed in the face by a roided up BEAST of a human being.
