Riley Marcus Dunwich, better known as "Thick Riley", is a Pro Wrestling manager, best known for having managed both the first ever SAPW Grand Champion, Cthulhu Jr., and The Walkers Brothers in SAPW. His introduction to AES seemed innocent enough with the plucky heavyset southern manager acting as translator for fan favorite, Cthulhu Jr. At Cthulhu Jr's side, Thick Riley stood by his side as Cthulhu Jr. went up against opponents like Bucky Foxworthy and Daiki Kaito. Over time, Riley started to become more and more aggressive with Cthulhu Jr.'s training, slowly showing his true colors as a bad man who had ownership over Cthulhu Jr. and abused him to make sure he held the World Title.
After Cazz Jordann earned a shot at the SAPW Grand Championship, Thick Riley tried everything in his power to make sure the Tattoo shop owner would not walk away with the title. But, in the end, Cazz ended 2012 as SAPW Grand Champion, defeating Cthulhu Jr. in a 2/3 pinfalls match. After the match, Thick Riley tried attacking Cthulhu Jr., but Cthulhu Jr. fought back, eating his eye and running away from Thick Riley. Later on the next year, Thick Riley returned with a glass eye for a match against Cazz Jordann at Renaissance Night 1 in a landmine match, ending in Thick Riley stepping on a landmine and getting knocked out.
He survived, however, sporting an eye patch and offered his services in managing The Walkers Brothers. Under him, The Walkers managed to earn several shots at the SAPW tag team championships, but The Walkers put blame on Thick Riley for any assistance he gave the two only ended up backfiring for the two brothers, leading to them dropping Thick Riley as their manager. With that, Thick Riley disappeared from the world of AES. Only time will tell should Thick Riley ever return to AES.
