He is the cousin of Sean Cassidy, the Banshee, a member of the X-Men. He was also once the only friend of the Juggernaut. His original principal power was that he could generate blasts of heat through a wooden medium, such as the shillelagh that he often carries. He has a rivalry with Sean, mainly because Sean won both Cassidy Keep, their estate, and the family fortune from Tom in a game of dice. They were also rivals for a woman named Maeve Rourke, whom Sean married. While Sean was away, working for INTERPOL, Maeve gave birth to their daughter, Theresa.
