The heel with the shaved head and all the chest tats is Marius Al-Ani.
This Link to the 2014 Roster might help. They have wrestlers listed on their site, but you have to register.http://www.cagematch.net/?id=8&nr=583&page=16&year=2014
Some guesses: Arabian Star, Juvenile X, and Mike Skull. It's sort of hard to ID folks from some of the angles. And not everyone has a Roster Image.
Guy in the yellow jammies is "The Arabian Star," Hakem Wakuur; Guy in red is Juvenile X, I think; the over-tattoed fellow looks like Marius Al-Ani;
Overall, he's won only 27.1% of his matches, but I'd like to see some of his victories over wrestlers that mostly have defeated him: Adrian Severe, Maxi Schneider, Johnny Rancid, Juvenile X (1/5), Markus Antonius (1/3), Arabian Star, Veit Müller, David Finlay, Michael Schenkenberg (1/1), and Vincent Heisenberg (1/1).
Juvenile X has a better record than, Marius (40.9%), but some of his victories vs. wrestlers that generally dominate him that I'd like to see are: T-K-O, Adrian Severe, Big Brother Steve, Mexx, Muslim Sultanov, Julian Nero, and Säx Mäx.
In contrast, Arabian Star is someone I'd enjoy seeing demolished as often as possible by: Mexx, Adrian Severe, Juvenile X, Big Brother Steve, Tommy Blue Eyes, Veit Müller, T-K-O, Bad Bones, Freddy Stahl, Marius Al-Ani, Marcus Antonius, Michael Schrenkenburg, Axel Tischer, BAM, Bernd Föhr, Chaos, Felix Reiter, Ivan Markov, Jack Hammer, Joe E. Legend, Martin Nolte, Robbie Dynamite, Tim Karsten, and Will Breaker
Almost left out Arabian Horse. Star beat him, but I'd like to have seen him win a rematch!
