==Biography==
===Early Life===
Sean Cassidy was born in County Mayo, Ireland to unnamed parents, and his lineage to the Cassidy family made him the heir of to Cassidy Keep. With his new fortune, Sean went off to Trinity College where he earned his bachelor degree of science, and later learn of his mutant power to cause sonic vibrations with his voice. He demonstrated this ability when saving Maeve Rourke from the police, and developed romantic feelings for her. Sean also started to compete with his cousin Tom for Maeve's affections, but Maeve would choose Sean over Tom. The two would later get married, but Cassidy would become an Interpol agent, leaving Maeve to give birth to their daughter Theresa by herself.
===Becoming Banshee===
Sean would later learn of Maeve's death from a bombing, but wouldn't learn of Theresa since his cousin Tom got custody and raised her himself. Though Sean initially tried to escape his anguish by doing countless Interpol missions, but he would turn to a life of crime that dodged the authorities. Cassidy would get himself intertwined with the Factor Three, being forced to do their bidding when they strapped explosives on his headband. Given the code name "Banshee", Sean came across the X-Men and Professor X removed the headband, allowing Cassidy to help them stop the Factor Three's leader Mutant Master. Afterward, Banshee joined the X-Men, being first sent to stop the sentient island Krakoa.
During his early tenure with the X-Men, Cassidy met Professor X's colleague Moira MacTaggert, and developed romantic feelings for her. When the X-Men traveled to Japan to stop Moses Magnum, Banshee used his voiced to stop Magnum from causing earthquakes, at the cost of his vocal cords. After battling Proteus, Cassidy relized his feelings for MacTaggert, and decided to retire from the X-Men and began a relationship with the doctor. He briefly returned to the team to help them fight off Arcade, and later met his daughter when Tom Cassidy attacked the X-Men with Juggernaut. When the X-Men were kidnapped by the Phalanx's, Banshee worked with Emma Frost to save mutants, and later became the co-headmaster of xavier's institute.
Following the disbandment of Generation X and Moira's "death", Cassidy turned to alcoholism, but returned to form the X-Corps to make up for his past mistakes. The team didn't last long, as the corps was infilitrated by Mystique and attempted to kill Cassidy, but she was stopped when Banshee unleashed Abyss. Though his throat healed from Mystique's attack when she joined X-Corps, he could no longer use his powers. During a mission after M-Day, Banshee was killed when he was rammed by a blackbird jet, and he was buried at the Xaver institute.
