Early life
Mackle played as a
goalkeeper for his university
football side.[14] He also played
rugby union (up to university level),
basketball and
judo.[14] 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.[15] He cites fellow countryman
Fit Finlay as a huge influence on his wrestling style and inspiration for his success.[16]
Professional wrestling career
Early career (2004–2013)
Mackle began his training with Scottish Championship Wrestling, before moving on to train with the SWA/NWA Scotland under
Robbie Brookside (now a trainer at WWE NXT) and others. Of Brookside, he stated; "I don't think there is enough hyperbole to explain how good a coach he is...I can't think of a better coach I'd met in any sport".[15] After training at NWA Scotland, Mackle debuted for the Scottish Wrestling Alliance at the age of 20 under the ring name Damian O'Connor. He originally wrestled in Scotland and the North of England as a tag team called "Britain's Most Wanted" with Scott Renwick. Together the two won a variety of tournaments and tag team championships in promotions such as SWA (4 times), W3L (2 times), SSW and 3CW. While they never officially split up, they would both focus on singles competition around 2009. This proved to be fruitful for both and O'Connor started touring his native Ireland, the United Kingdom, mainland Europe and the United States. O'Connor would win the Heavyweight Titles in SWE, W3L, XWA, Pride as well as the Laird of the Ring Title in SWA. In 2009, O'Connor took over the SWA training school named the "Source Wrestling School". O'Connor has trained numerous wrestlers, including
Joe Coffey,
Joe Hendry and
Nikki Cross.[17]
Insane Championship Wrestling (2012–2016, 2018, 2021-present)
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. After a long feud with Drew Galloway, Damo defeated Chris Renfrew for the
ICW World Heavyweight Championship in Belfast on 27 February 2016,[18] marking the first time the title changed hands outside of Glasgow and making Damo the first ever Northern Irish-born champion. Damo defended the title in Ireland, the United Kingdom and the United States against the likes of
Drew Galloway,
Grado, VSK,
Jack Jester and others.[19] On 31 July 2016, at Shug's Hoose Party III, Damo was defeated for the Championship by Joe Coffey.[20]
On 11 November 2018. O'Connor (as Killian Dain) returned to ICW for one night only, defeating

steel cage match at Barred II 24 April 2022.[22]
In 2023, Damo challenged
Leyton Buzzard twice for the ICW World Heavyweight Championship. On ICW Fight Club they went to a no-contest when Andy Roberts interfered. Damo was given a rematch in a Three Way Dance at ICW's Get The F Out! PPV but was eliminated from the contest by Roberts.[23][24]
In June 2016, Mackle signed with

Matt Riddle following Riddle's match against
Arturo Ruas.[71] This led to a match between the two being scheduled for the 7 August episode of NXT. However, Dain attacked Riddle before the match could begin.[72] On the September 25 episode of NXT, Riddle defeated Dain in a #1 contender's street fight match for the
NXT Championship ending the feud. Shortly after, Dain would enter in a three-way feud with

Personal life
Mackle is a lifelong supporter of
Premier League team
Manchester United and
NBA team
Orlando Magic.[14] He has stated that he believes wrestling – unlike other sports – can be a uniting factor for people in his native Belfast as there are "no (sectarian) affiliations" in wrestling. He stated that he would not support Scottish football because there is "a lot of connotations" with sectarianism. He grew up in what he described as a
mixed area and is conscious of keeping political affiliations out of his public life.[76]
On January 17, 2019, Mackle married fellow WWE wrestler, Nicola Glencross, known by her ring name
Nikki Cross.[1]
