Powers: Banshee has the mutant ability to create a sonic scream which he can use in a variety of different ways. Flight, hyponisis, and basic destruction have been varieties of his power. There have been many times when Sean has spoken while he uses his sonic scream, but that is theoretically impossible unless he has two throats (which might be the case with his daughter, Theresa).
Origin: In one of the first uses of his mutant power, young Sean Cassidy saved the life of the beautiful Maeve Rourke. Shortly after, Maeve and Sean were married. However, Sean was pulled away from his dear wife by Interpol. During a raid, Maeve was killed, but was able to give birth to a little baby girl: Theresa Rourke. Her "uncle", Tom Cassidy, took her and raised her as his own daughter, never telling her about her father, Sean.
After defeating the Reavers, Banshee and Forge decided to search out the X-Men and try to join up with them again. They also noticed a change in the people on the Muir Island Complex. Moira, Legion, and the others began to act mean and dark. The influence of the Shadow King (in combination with Lorna Dane's new mutant powers) caused this change. However, it was only temporary and was resolved with the defeat of the Shadow King by Professor Xavier. So, Banshee joins up with the X-Men as a reserve member.
Banshee doesn't do much for a long while. He goes off and on between the X-Men and Moira until the Phalanx invade the mansion. As one of the four remaining occupates of the X-Mansion, Banshee is forced to destroy Professor Xavier's files as well as part of the mansion, to protect the next generation of mutants from the Phalanx. With the help of Sabretooth, Emma Frost and Jubilee, Banshee is able to rescue the new mutants, with the exception of Blink, who "died" saving him from Harvester.
In an attempt to find out where their students were, Emma mindscanned Banshee for a clue. The way that Black Tom had Generation X arranged was identical to the way Krakoa had the original X-men arranged. So, the two headmasters headed for Krakoa's last location, where they found a ship. No one was on it, so the two headed for Colorado, where the X-Men were being attacked. They were too late, so Banshee and Emma tried to find a safehouse to stay at. In Florida, Emplate confronted them with a bargin: the location of the students for Penance. Emma was planning to trade Penace (she wasn't going to, though), but Sean stopped her and ordered her never to go back to the Academy again.
Banshee takes Penance back to the Massachusetts Academy, where the
rest of his students are. Then, he heads for Muir Island in order
to get a clue what had happened to M (who was now two little girls).
He and Moira had a reconciliation, reviving a bit of their old relationship.
After getting the test results, Sean headed back to the school, where
Emma promptly punched him in the face.
