Power Description:

SONIC GENERATION :: Banshee can generate intense sound and make attacks of narrow or wide dispersal. The Sonic Scream can generate frequencies normally inaudible. Banshee can disrupt other sound-based effects by creating dissonance as his harmonics clash with the second source. It cannot function in a vacuum.

DISRUPTION :: Banshee can destroy a target's physical structure without resorting to a physical or overt energy attack. The molecular bonds that give a target its solidity are directly disrupted, with the result that the target collapses into dust, sand, liquid, or even vapor. Banshee can Disrupt any target within both line-of-sight and range. The range is roughly 500 to 1000 feet. FLIGHT - Banshee can fly through air by generating a sonic scream and using it to bounce off the resulting sound waves as a means of propulsion. Banshee requires a special rigging that allows him to glide on the sonic waves he creates. He can achieve cruising speeds of 150 mph. .

HYPNOTIC VOICE :: Sean can modulate his voice to create sympathetic vibrations and gives him the ability to subtly influence people's subconscious mind by changing the tones and vibrations of his voice using sonics.

SONAR :: Banshee is able to use sound to determine location, distance and movement of objects, terrain and people. This process requires him to make periodic checks to update his mental image of his surroundings. SONIC SHIELD - Banshee is able to create Incredibly strong barriers of sound protecting himself and others from all types of attacks except telepathic.

INDUCE SLEEP :: Banshee can induce sleep by stunning the subject with high frequency waves that induce unconsciousness.

VOCAL DISORIENTATION :: ability to change someone’s balance, by affecting their equilibrium using his sonic scream Vocal Trance:

VOCAL STUNNING :: ability to affect the fluid in someone’s ear causing the person to go unconscious. SOUND AND VIBRATIONAL

IMMUNITY :: Banshee's body, hearing and equilibrium are unaffected by his power or other similar sound or vibrational abilities up to his own rank.

Banshee's superhumanly powerful lungs, throat and vocal cords could produce a sonic scream for various effects, in concert with limited, reflexive psionic powers which directed his sonic vibrations. He could hover or fly at the speed of sound, and could carry at least one passenger. He could overwhelm listeners with deafening noise, stun them with tight-focus low-frequency sonic blasts (effective even against shielded ears by penetrating the skull via bone conduction), plunge them into a hypnotic trance, disorient them, nauseate them, or simply render them unconscious. Using sonic waves, he could rapidly vibrate himself or other masses at will. He could generate sonic blasts which struck with tremendous concussive force, liquefying or outright disintegrating targets at his highest levels of power. By radiating sound waves outward and reading the feedback, he could locate and analyze unseen objects in a sonar-like fashion. By modulating his scream's harmonics, he could confuse most scanning equipment. He could instinctively analyze, replicate, and block sonic waves or vibrations from other sources. Banshee generated a psionic field which protected him from the detrimental effects of his sonic vibrations, though his sonic powers could still injure him when pushed beyond safe limits. His physiology seemed fully vulnerable to conventional injury when his sonic powers were not engaged. Banshee had selective hearing, enabling him to focus upon, enhance, or totally block out any given sound in his environment; this shielded him from the deafening sound of his own screams, and made him a superhumanly acute eavesdropper in surveillance situations. Sean and his cousin Black Tom were immune to each other's natural mutant energy powers, though Sean's immunity did not extend to the new powers Tom later developed via artificial mutations.


ADMINISTRATION :: Sean is quite good at keeping things organized and coordinated, keeping track of the various aspects of an organization and making sure nothing is neglected, and keeping things documented in case the need arises to go back and check over something.

BLUFF :: If anyone could be have said to have kissed the Blarney Stone it's Sean. He has the gift of gab, and in years of working undercover it has kept him alive on more than one occasion.

COMBAT STYLE (Aerial) :: Sean can use Agility instead of Strength to attack while flying. He can also use Agility instead of Intellect for declaration order during aerial combat.

DIPLOMACY :: Sean has moved through most levels of society, from the lowest to the highest, he adapts well to all situations with a practised ease. He can negotiate, act as an advocate, and bring people together and do it all with a benevolent air.

ESPIONAGE / LAW ENFORCEMENT :: Sean has a career as both a police officer and Interpol agent.

LEADERSHIP :: While Sean isn't usually the one in charge, he is capable of keeping a team together and focused on goals. MECHANICS/REPAIR - Sean has an intuitive understanding of how parts come together to make machines work and how to fix them.

STEALTH :: The art and science of avoiding detection. Banshee is very aware of his body, of it's movements and most importantly of it's limits. This understanding allows them to move with the utmost care and silence, and also to freeze stock-still in a concealing shadow when necessary in an effort to avoid detection. Likewise, he can also prowl about rooftops and the like; high-technology electronic systems and some superpowers and heightened senses, however, will negate this ability.

WEAPON STYLE (Guns) :: Modern personal firearms of all types-handguns, rifles, shotguns, submachine guns, including laser, stun, and concussion varieties.

A gifted detective, veteran undercover operative, and formidable unarmed combatant, Cassidy was an excellent marksman and a competent amateur machinesmith, well-versed in combat strategy & tactics and teamwork drills. An effective educator, organizer and lobbyist, he was also an avid American country music aficionado and skillful amateur piano player.


APPROACHABLE :: There's something very approachable and nonthreatening about Sean. This means that it is often Sean that people come to with their problems or questions.

ATHLETE :: Naturally athletic, Sean has won multiple awards for athletic achievement. Much of this is due to training, but natural ability and aptitude also plays a lot in to it. This athletic ability can be in any sport or athletic event.

CHARISMATIC :: Sean just seems to have that special magnetic charm or appeal about him. There is something about Sean that people just can't seem to resist. He seems to have a personal attractiveness or interestingness that enables him to influence others.

COMBAT REFLEXES :: Sean's years law enforcement have razer honed his ability to react to threats almost instantly, meaning that he is very difficult to surprise and is extremely effective in close-range hand-to-hand combat

CONFIDENCE :: Sean possesses an untouchable air of superiority that makes others instinctively realize he is in charge.

POKER FACE :: Sean is totally unflappable, on the outside. No one knows what he's thinking or how Sean actually feels if he doesn't wish it known. While he is ordinarily not a guarded person with his emotions, if he wishes to hide something, or fake something or even tell a point blank lie, he can and you're likely to believe him when he does. If there is one thing the Sean isn't thought to be is a man who lies or bluffs.


SENSITIVE VOCAL CORDS :: His vocal cords are susceptible to injury from excessive strain in using sonic powers. He can also survive normally fatal throat wounds at the temporary cost of his sonic powers.

Character History:

Sean Cassidy Is the clone of the original Sean Cassidy that joined the X-Men in the 1960's. Moira Mctaggart found a mutant who called "Mother" who could recreate any person from their genetic material and she could return memories to the body through an unknown psionic means.

Sean believes he is the grandson of the original Banshee and is unaware that his father is also a clone. The secret is only known by Moira who was in love with the original Banshee and has not let him go.

Ireland's storied Cassidy clan is an ancient and noble lineage steeped in heroism, secrets, adventure, feuds and tragedy, all of which Sean Cassidy would inherit in some measure. The family's ancestral home is Cassidy Keep, a fortress-like castle in a remote, sparsely populated coastal area of County Mayo, overlooking the Atlantic Ocean from high atop the granite cliff Cassidy Crag. The Cassidy presence there predates historical records, and Cassidy Keep itself was built by Liam Cassidy over a thousand years ago to defend the Irish coast against Viking raiders. The Keep also covertly sheltered the "Families" (diminutive enchanted leprechauns or elves). In recent decades, the castle's Seneschal (steward), Eamon O'Donnell, has served as both caretaker of Cassidy Keep and guardian of the "Families". Born and raised in Cassidy Keep, Sean Cassidy had a happy boyhood there, fantasizing about fighting dragons and rescuing damsels. During adolescence, Sean discovered his mutant sonic powers but concealed them - partly because his wail spooked the superstitious elders of the community, who likened it to the ghostly banshees of Irish lore

Sean's cousin, "Black Tom" Cassidy, became his lifelong rival. Like Sean, Tom was secretly a mutant; Tom was a gambling man who loved to live dangerously. Tom was next in line to inherit the Cassidy estate and its modest wealth, but gambled away these rights to his cousin Sean in an ill-advised wager. Despite this setback, Tom remained a suave, charming, Oxford-educated ladies' man, often making the less cultured Sean feel like a hapless country bumpkin by comparison. As young adults, the cousins competed for the affections of Maeve Rourke, whom Sean met in Northern Ireland. He had been hitchhiking home from a concert when he was harassed by corrupt policeman Sergeant McLanahan, who seemed keen on arresting Sean as a supposed terrorist, despite lacking evidence. A passing motorcyclist (Maeve) rescued Sean, but McLanahan chased them across the Irish border and sent their motorcycle off a cliff, forcing Sean to use his sonic scream to fly him and Maeve to safety. Sean took Maeve back to Cassidy Keep, where she adapted surprisingly quickly to her discovery of Sean's bizarre powers. She just as quickly grew fond of both Sean and his charming cousin Tom, each of whom was quite smitten with her. Maeve dated both cousins for months, apparently genuinely torn between the two, but chose Sean as her escort for the university ball. Badly injured when a vengeful McLanahan ran him off the road en route to the university, Sean sent Tom to escort Maeve in his place. Tom initially offered no explanation for Sean's absence, and the disappointed and puzzled Maeve accompanied Tom to the dance; but Tom, unable to lie to her, eventually confessed Sean's true circumstances. Touched by the gesture, Maeve called Tom her dearest friend, though her heart clearly belonged to Sean. Stepping aside gracefully, Tom later served as best man at their wedding; but losing Maeve to Sean accelerated Tom's gradual, secret descent into immoral, dangerous and increasingly criminal acts as he dabbled in mercenary work and various illegal ventures.

Sean, meanwhile, graduated college with a science degree and went into law enforcement. Well over two decades ago, he became an agent of the international police organization Interpol. As a rookie agent, Cassidy failed to prevent the terrorist organization Hydra's enslavement of weapons specialist Patrick Lipton, whom Cassidy subsequently believed dead. Later, Cassidy hunted down the Russian mutant serial killer Arkady Rossovich (the future Omega Red) with the aid of Magneto and Interpol colleague Magrite Deveraux (who was slain by Rossovich). He also teamed with fellow agent Daniel Peyer to infiltrate the offices of mob boss Almadavor until the mercenary Deadpool interfered, saving Sean's life but ruining the operation by killing Almadavor. While Sean was on a long-term deep cover assignment that kept him away from home with no contact for many months, Maeve gave birth to their baby daughter Theresa; but mother and child were soon caught in a terrorist bombing and apparently killed. Sean had not known Maeve was pregnant, and the few who knew about the newborn baby decided it was better to conceal her existence from Sean, lest it cause him further pain. Theresa secretly survived, rescued and adopted by her "uncle" Tom. When Sean finally returned and learned of Maeve's death, Tom considered telling his cousin the truth about Theresa; but a grief-crazed Sean lashed out at Tom, blaming him for not protecting Maeve in his absence, and accidentally gave Tom a crippling leg injury. Further embittered, Tom decided to raise Theresa himself in secret. Sean became an obsessive workaholic and, perhaps hoping distance would help ease the pain, he briefly transferred to the NYPD in New York City, where he once aided young mutant telepath Emma Frost (though she mind-wiped his memory of the incident). He soon rejoined Interpol, and encountered the mutant brawler Logan (later Wolverine) while apprehending criminals in Calgary, Alberta. After years of international assignments, Sean came home and led an undercover operation targeting his cousin, Black Tom, by now a major criminal. Tom was soon sentenced to life in prison, but Theresa remained unaware of her true parentage since Tom had long since sent her to a distant private school to shield her from his darker dealings.

Apparently by now aware of Sean's mutant powers (perhaps due to an investigation of Cassidy's exploits by the Weird Happenings Organization), Interpol sent Sean back to America to infiltrate the rising mutant subversive organization Factor Three. The increasingly disenchanted Sean, still mourning Maeve, quit Interpol for good and became a freelancer, secretly dabbling in minor crimes. Ironically, this attracted the attention of Factor Three (mostly mutant criminals themselves), and their deputy leader Changeling tried to recruit Cassidy. When Sean refused, they forced him to wear a remote-controlled explosive headband which would detonate if tampered with. Thus enslaved, Cassidy (code-named Banshee) performed criminal missions for Factor Three under the supervision of their loyal agent Ogre, a gifted human machinesmith. In a bitter twist, Cassidy soon found himself on Interpol's wanted list. Banshee and Ogre were ultimately defeated by the X-Men, who freed a grateful Banshee from Factor Three's service. Cassidy later helped the X-Men bring down Factor Three and exposed its "Mutant Master" leader as an extraterrestrial, prompting the defeated villain to kill himself. Banshee kept a low profile thereafter, apart from escaping the anti-mutant Sentinel robots with the aid of the X-Men, and skirmishing with Captain America and the Falcon while fleeing the mutant-hunting Secret Empire.

A diehard country music fan, Cassidy was in Nashville, Tennessee when Charles Xavier recruited Sean and several other mutants to form a new squad of X-Men to rescue the previous X-Men from the living island Krakoa. After the successful completion of this mission, Banshee considered leaving, since he felt too old for the mostly-youthful group, but Xavier and team leader Cyclops convinced him to stay.
