Black Tom Cassidy (Thomas Samuel Eamon Cassidy) is a supervillain appearing in American comic books published by Marvel Comics. The character is usually depicted as an enemy of the X-Men, and of his cousin, Banshee. In addition to fighting the X-Men, he has clashed with Deadpool a number of times. Black Tom is a mutant who can manipulate, bond with, and project energy through plant life. He is also capable of issuing concussive blasts with a wooden object, usually a shillelagh. Tom was the black sheep of a prominent Irish family. He secretly raised Banshee's daughter Siryn, of whose existence Banshee was unaware, and conscripted her into his criminal gang. Black Tom was also a longtime criminal partner of the super-strong villain Juggernaut, until Juggernaut's reformation. Black Tom Cassidy makes his film debut in Deadpool 2, played by Jack Kesy.
