Black Tom Cassidy is the cousin of Banshee and also his archenemy, an Irish mutant born with the ability to fire energy-beams from any wooden surface, he has a fondness of utilising weapons such as shillelaghs to focus his power, he has also displayed some control over plants (florakinesis) and was even mutated into a plant-like monster at one point: though he is back to a human form these days - he is the black sheep of his family and a shameless criminal who will do almost anything if he feels it will further his influence or make him wealthy, despite his ruthlessness he has admitted to having a close friendship with Juggernaut - though the two men have been at odds over Tom's merciless murder of a young mutant named Sammy Pare.
