Damian Mackle (February 20, 1985) is an Irish Professional wrestler working by ring name Big Damo and Damian O'Connor. He is currently signed to WWE under the ring name Killian Dain.

Better known to many as Damo, the stout Irishman is a full-time professional wrestler and wrestling coach based in Glasgow.
Damo has travelled the length and breadth of the UK to train under various experienced veterans of wrestling. Most recently O'Connor has spent a lot of time with current WWE NXT trainer and British Wrestling legend Robbie Brookside. Previous to that he has learned under Doug Williams, Prince Fergal Devitt, Johnny Moss and many others.
Damo's style has evolved as he has gotten bigger; developing from a technician into a brawler. He has spent the last few years marrying the two to make his style as brutal and realistic as he can.
Whether in singles or tags, you'll be sure to see O'Connor taking it to anyone, regardless of shape, size or style.
O'Connor has also trained various upcoming stars, including Nikki Storm, Joe Coffey, Mark Coffey, Joe Hendry, Jackie Polo, Viper and many more. On Monday 18 January, it was announced that he as well as Jimmy Havoc and Will Osprey will be added to the TNA Maximum Impact Tour in the UK.
