at times, he will go through lengths to come across as someone whose background was more working class and average than his truly was.  He values the importance of being resilient and 'tough enough' to make difficult and time-sensitive decisions; this no-nonsense approach sometimes manifests as a fault, as he risks hasty reactions and being unjustly critical at weakness.  That aside, Sean can be charming if in a bit of a rabble sort of way that emphasizes the 'everyday guy' and punk aesthetic he aspires to.  Sean is competitive, intelligent and energetic; he is also short-tempered, a poor business administrator, and short-sighted.<br/><br/><strong>Hobbies:</strong>Bar games (darts, pool, cards, etc.) Drum playing, Guitar playing, Martial Arts/Unarmed Combat, Music, Singing, Football ("Soccer") fanatic, Weapons/Firearms enthusiast<br/><br/><strong>History:</strong>Sean Cassidy was born to two non-mutant parents, Haigan and Riona, in County Mayo Ireland.  Due to their economic influence and proud history within the area, the family line was largely considered nobles by the town, despite being in an age where such notions were fast dying.  Much to the disappointment of his extended family, Sean was an often physical and sometimes oafish child.  At no time was this more apparent than when he was playing with his cousin, Tom.  Tom was soft-spoken and mannered, exemplifying the traits that the contemporary Cassidy clan valued most.  This was notably problematic for Sean, since even at an early age, Tom had a secretive vicious and mean streak.  Tom would often going through elaborate pranks to publicly provoke Sean's uncontrolled temper, or simply have him look brash and embarrassing to a family that placed a high value on subtle grace.<br/><br/>It was perhaps due to feeling at-odds with the more genteel background that he sprung from, by his early adolescence Sean had begun to push away from his family's lifestyle in attitude and appearance.  This was most embodied in him becoming enraptured with both the contemporary and historic punk scene.  When his parents said 'good schooling and etiquette', Sean only attempted to drown it out with the sounds of The Pogues, Sex Pistols, Apostles, and Levellers.  He did his best to distance himself from the family and upbringing much to their ire; most of all, of course, he tried to disassociate himself from his glib-tongued and manipulative cousin.<br/><br/>Sean's mutant abilities would first manifest as he was trying to mimic the heavy-lunged, shouting growl of Million Dead while alone in his room.  Instead of simply brash notes coming forth from his throat, a concussive blast shot forth that sent his bed, posters, and the many strewn about dirty clothes forcefully against the wall.  Once he learned to tap into the ability the first time he was able to slowly refine it, experiment with it, and start planting the knowledge seeds that would form the basis of many of his future powers.  Sean made the calculated decision not to share the development with his family, believing that it would only further cause him to be looked upon as a pariah.  Meanwhile, unbeknownst to Sean, Tom Cassidy was also in the process of learning about his important genetic differences.<br/><br/>When Sean was sixteen he would meet his future wife, Maeve Cassidy, while attending school.  Due to his often subversive dress and cocky attitude Sean was often the prime suspect of the school administrators; this was certainly the case when an unknown student had placed pipe bombs within the school.  Maeve covered for Sean with an alibi when the school and law enforcement came in, much to Sean's surprise.  Maeve confided to him that she believed him to be innocent because of the protective, moral character she had quietly observed him displaying.<br/><br/>Sean's cousin, Tom, unfortunately, was equally taken with Maeve the moment that he met her.    Maeve was soon torn between the two; Sean represented her own instinctual interests, while Tom was looking to be the quiet and successful businessman that Maeve's parents would prefer her to be with.  In the end it would seem that biology would aid in her decision, as Maeve became pregnant with Sean's child still months prior to her eighteenth birthday after a reckless moment she shared with the youth.<br/><br/>Sean, while terrified, begged Maeve to not terminate the pregnancy.  She made her position clear enough:  an aspiring punk-rocker from an estranged, if wealthy, family was not capable of being a fit father.  Faced with his realistic options Sean chose to fight for Maeve and his child.  Unbeknownst to Sean, even though they now shared an unborn child together, a slowly-twisted Tom was still actively working on seducing Maeve away from him.<br/><br/>Having never developed the carousing skills to succeed in family-oriented businesses, and lacking the education for many skill-based professions, Sean chose to put aside his anti-authoritarian philosophies in order to join the An Garda Síochána as an officer of the law.  Simply put, if Sean no longer had the luxury of trying to change the system from outside it in iconoclast culture, he opted to try and work the system from the inside.  His natural physical prowess and urge to protect the innocent made him a surprisingly good fit despite his background; while it was not the life Sean imagined it was starting to look like a life that he could be happy with all the same.<br/><br/>That sense of peace would be far too short-lived, however.  While Sean was working as an under cover officer, Maeve and their young daughter, Theresa, were involved in a blast targeting the home they had built for themselves in Rathmines.  The attack was apparently done as retaliation from someone who had learned of Sean's cover, but the exact identity of the attacker remains unknown.  The fact that the news had taken several days to reach Sean, whom was still using a secret identity at the time, infuriated Tom.  Tom accused Sean of always being incapable of taking care of Maeve, and proclaimed that this would not have happened if he had not taken her from him.  Sean was viciously and physically attacked even in his grief, and was left with both a broken leg and Tom's sworn enmity.<br/><br/>Sean would choose to turn away the comfort of his native country, as well as the approval of his parents, for the option of not being around those things that most reminded him of the life that he and Maeve had started for themselves.  No longer feeling the need to be settled due to concerns for a family, he moved to New York City, determining to continue his tract through a criminal justice education and an internship program with Interpol.<br/><br/>It was while working under Interpol that Sean first encountered Xavier's Institute for Higher Learning.  He was initially dismissive of their mission, however began to realize the benefits in seeking acceptance at the institute.  The powers that he kept hidden from the world could be used without judgement; furthermore, he no longer had to pretend that the punk-rock aesthetic he wore in undercover operations was not truly part of who he was.  In some ways, the man he pretended to be was more the man he truly was.  In short, he would be accepted, he could learn about his own abilities, and provide protection to those in need at the same time.  Perhaps more importantly, he could forget about the life back in Ireland that still hung heavy in his memories.<br/><br/>Sean's time at the school has been a beneficial one.  His experience in law enforcement, police procedural, and firearms has been helpful in the mission of the institute.  Furthermore, his own abilities have continued to develop.  He has developed rivals and friends, mentors and pupils.  He has used his passion and skill in the brash styling of punk music to have a few makeshift bands and performances during his time at the Institute, which has helped his popularity among some of the younger and more iconoclast students.<br/><br/>Most recently, he was severely injured during the recent attack on the school.  Sean's throat was fully slit by Mystique while she was under the guise of a student, and while his powers allowed him to recover from the attack, returning from that critical wound in combination with a broken leg and many lacerations has been difficult.  As a somewhat prideful, independent man, Sean has made quite the terrible patient, and the staff assisting in his recovery are likely even more relieved than Sean to see his autonomy start to return.<br/><br/><span class="bbc_size" style="font-size: 18pt;"><span class="bbc_u">Mutations and Powers</span></span><br/><strong>Classification:</strong>Generational Skip<br/><br/><strong>Type of mutant:</strong>Alpha Level. Mostly, but not completely in controlled/mastery of powers at this time (~85%).<br/><br/><strong>Powers:</strong>As his canonical counterpart, Sean Cassidy's lungs, throat, and voice may combine to do a variety of supernatural sonic-based effects, which is complimented by an assortment of low-grade reflexive psionic powers.  These abilities help to give him strong aptitude in combat situations as well as notable utility.  This, of course, makes his throat and lungs his greatest asset, but also his greatest liability since smart foes are able to identify it as a point of disablement.  Excessive use of his abilities in a condensed period of time will likewise cause vocal strain and eventual hoarseness, which will prevent him from power use until recovery.<br/><br/><em>Psionic Shield (Self-limited)</em>- Shawn has a limited psionic shield whose sole utility is to prevent him from generally being affected by his own powers.  In extreme situations, however, as detailed in the following power entries, this shield may partially or fully fail.<br/><br/><em>Low-Wave Frequency Scream</em>- Sean may stun an individual or group, even with shielded ears, by letting out a scream that penetrates the skull via bone conduction.  By varying the degree of the scream he may coax them into nausea, disorientation, or simple unconsciousness.  While normally protected from these effects via his<em>Psionic Shield</em>, if Sean seeks to cover too large of an area his protection has a chance of failing, effecting him as well.<br/><br/><em>High-Wave Frequency Scream</em>- Sean may generate blasts of high profile concussive force, which can be aimed to knock back or physically damage an opponent or a close-clustered group.  While canonically Sean's highest achievement of this power allows outright disintegration/liquification of his opponents, this is not a level of power he has access to at this time.  For storytelling purposes, at the GMs discretion, the higher aspect of this power may be accessed in the presence of a life-threatening level of adrenaline or equal stimuli; however, it's use would easily overcome Sean's<em>Psychic Shield</em>and leave him both severely wounded from the effects of his own attack and completely depleted in the process.<br/><br/><em>Inanimate Destruction</em>- Sean may use his scream to shatter, warp, or otherwise destroy an object.  Particularly substantial objects will require more power, may be beyond his capability, or compromise his<em>Psionic Shield</em>.<br/><br/><em>Sonic Shield/Deflection</em>- Sean may propel a wave of sonic energy in order to form a sonic shield against incoming objects, including weapons and attacks.  Unfortunately, Sean himself is uncertain of the full limits of this power (which can be exemplified no better than the attempt to deflect a crashing plane resulted in the Marvel character's canonical death.)<br/><br/><em>Flight</em>- Sean may hover, or fly at the speed of sound, and carry a single person without burden in the process.<br/><br/><em>Sonar</em>- Much like a bat Sean may radiate soundwaves outwards and interpret their feedback.  This allows him to have a level of orientation and sense of object placement, even when his sight is affected.<br/><br/><em>Mimicry</em>- Sean has the ability to reach and repeat sound frequencies he has heard, even those well outside a normal human's vocal register.<br/><br/><em>Selective Hearing</em>- Sean has the ability to selectively 'phase out' sounds around him, providing him immunity to some of his own abilities, and superior eavesdropping skills in noisy situations.<br/><br/><em>Vocal Stamina</em>- Sean's throat, lungs, and vocal chords are super-humanly resilient, and he is capable of withstanding damage and recovering from throat wounds that would have permanently muted, if not outright killed, many others.  Strength, of course, does not equate to invulnerability and it remains an effective targeting point to harm the mutant.<br/><br/><strong>Abilities:</strong>Things not given to your character by their mutation. Ex: multilingual, martial artist, etc.<br/><br/><em>Carousing</em>- Sean not only is a natural in a party crowd, but he has had reason to do so under pressure.  He knows how to be charismatic, hold his liquor, play a mean game of pool, and blend in with the crowd.<br/><br/><em>Firearms (Advanced)</em>- Sean is very competent with firearms due to often being unable to rely on his mutant abilities when he wishes to maintain cover.  He is capable of teaching others this training to a degree.<br/><br/><em>Musician</em>-  Sean has a lifelong love with punk rock music.  His supernaturally strong lungs and vocal chords make him a an unusual, if far from classically-trained, singer and he has the ability to play the guitar, bass, and drums.  He is all garage band and no orchestral background, however.<br/><br/><em>Police Procedural</em>- Sean has experience in police procedural and investigation techniques due to his history at both An Garda Síochána and the New York City division of Interpol.<br/><br/><em>Unarmed Combat (Intermediate) -</em>While Sean favors keeping his distance in a fight, his training as a police officer (as well as a streetfight or three,) has provided him some skill in hand-to-hand situations.<br/><br/><span class="bbc_size" style="font-size: 18pt;"><span class="bbc_u">School Information</span></span><br/><strong>Classes Taught:</strong>Law/Criminal Justice (College Level), Assists Xavier with General Institute Activities<br/><br/><strong>Staff Relations:</strong><br/><br/>Ezra "Streak" Bell - Coming Soon/TBD<br/><br/>Kyle "Vyrus" Morgan -  You can't live under the thumb of your adviser all the time, right?  Sean and Kyle initially bonded over their mutual interest in marksmanship, but time spent hanging out soon turned into an opportunity for sharing other interests.  Knowing that Kyle has more than enough hierarchical advisement from Scott Summers, Sean has taken up more of the buddy role.  Sean is actively interested in the hacker culture that is more Kyle's domain, and the two share both their mutual interests and the occasional kvetch session.<br/><br/>Laura "X-23" Kinney - Sean and Laura quickly bonded over punk music, politics, and aesthetic.  He's an open admirer of her resilience and frank, no-nonsense way of dealing with the world.  The fact that she looks up to him for guidance in matters of counter-culture both thrill and often amuse him.  He openly advocates for her while trying to keep enough of a distance to allow her that unique style of independence.  Many times, particularly after Sean's injuries, the two managed to spend hours together communicating barely at all, though appreciating the company of the other while listening to music.<br/><br/>Marcel "M"  St. Croix - Marcel and Sean are tumultuous frenemies who seem incapable of either entirely getting along or fully disliking each other.   Their already strong personalities seem to only amplify when they are too close to each other; Sean's punk-leaning greater-good and anti-establishment philosophies are always clashing with M's hedonistic, indulge-in-the-moment ways.  When they aren't fighting they are sharing a drink together or laughing, though, providing some quiet affirmation that when the proverbial chips are down, they are loyal defenders of each other.<br/><br/>Samira "Sam" Kane - Sean quickly learned to values Samira's connection to nature and live-in-the-moment ways.  While his recent injuries have largely prevented their walks, talking, and general not-too-serious-now decompression sessions, with the start of the school year they should be back to their routines.
