Biography

is an Irish Professional wrestler working by ring name Big Damo and Damian O'Connor. He is currently signed to WWE on the Smackdown brand under the ring name Killian Dain. He wrestled regularly on the European wrestling circuit for promotions including Insane Championship Wrestling, Westside Xtreme Wrestling, Revolution Pro Wrestling, Scottish Wrestling Alliance, British Championship Wrestling, HXC Wrestling, Scottish Wrestling Entertainment, WCPW, XWA, PWU and many more. Mackle played as a goalkeeper for his university football side. He also played rugby union (up to university level), basketball and judo. He stated that as a child he was attracted to professional wrestling because of the "larger than life" personas and face paint of wrestlers such as Sting and The Ultimate Warrior. He cites fellow countryman Fit Finlay as a huge influence on his wrestling style and inspiration for his success. O'Connor wrestled sporadically for ICW between 2009 and 2012 under various gimmicks, but his return in November 2013 saw him debut as Big Damo. Damo defeated Chris Renfrew for the ICW World Heavyweight Championship in Belfast on February 27, 2016, marking the first time the title changed hands outside of Glasgow and making Damo the first ever Irish-born champion. On 31 July 2016, at Shug's Hoose Party III, Damo was defeated for the Championship by Joe Coffey.
