"The Mercenary" Pain is known to have been at Exist Pro Wrestling for quite a while and is a former Exist Pro Wrestling Champion.

He is a major threat within the company due to his powerful in-ring performance and intimidating nature. Pain doesn't need to speak up about anything, as he uses his demeanor and performance to comunicate his intentions to the crowd and wrestlers at the promotion.

Pain is known to have been working in collaboration with the GGM whilst he was holding the Exist Pro Wrestling championship, although due to altercation with the GGM's attitude towards him, he is no longer under the GGM's instructions, now free to show all his true potential in whichever way he finds fitting.
