Kid Omega

Kid Omega (real name Quentin Quire) was a former pupil of Xavier and a youth who had promising potential, at least in the eyes of Xavier, yet he would become a traitor and formed his own "Omega Gang" with the intent of brutally assaulting and even killing any non-mutants they came across - he is also an Omega-Level mutant, meaning that he is capable of surviving even after physical death: which he has apparently done several times.

Promising Potential
Quentin joined the Xavier Institute and was welcomed as a great student, quickly becoming one of Xavier's most prized pupils - in fact Xavier helped Quentin to develop his mutant abilities when they first surfaces, since they orginally caused him some distress. Despite his popularity however the Stepford Cuckoos found something disturbing about Quentin from early on, their fears however were dismissed by Emma Frost as little more than jealousy over his success.

Fall From Grace
Quentin would continue to be a fairly happy student at Xavier Institute until he was contacted by his parents on his birthday and informed he was adopted - this revelation had a severe effect on Quentin's mind as he proceeded to get a haircut based on an anti-mutant newspaper's depiction of a mutant overlord which was published on the year of his birth.

Quentin would then join in on calls for venegance for the murder of a mutant by the name of Jumbo Carnation and took to wearing clothes based off the mutant overlord depiction - at this point he started to debate with Xavier over the nature of the Institute, questioning whether Xavier would allow any dream other than his own to flourish.

Omega Gang
Shortly after this debate Quentin took a gang of like-minded mutants to town - all dressed in similiar clothing - and convinced them to take a dangerous drug known as Kick, they then proceeded to harass a group of humans in an alley and brutally assaulted them, going as far as killing some of them.

When the group return to the Institute they are confronted by Xavier but Quentin evades detection - later Quentin takes his newly named "Omega Gang" to a tattooist and have Omega symbols tattooed onto their arms and proceeded to attack the U-Men, when they returned to the Institute the gang ambushed Xavier with a baseball bat before clamping a thought-proof helmet over his head.

Riot At The Institute
The next day sees the Xavier Institute have an "Open Day" for parents and media - Quentin declares it "open seaseon" on humans and begins a riot, some of the students join in but most of the damage is caused by Quentin and his Omega Gang until they are defeated by the X-Men, however the battle against Quentin was not so easy - thankfully for all Xavier managed to break free and confronted Quentin, calling his attempt at revolution "flimsy".

However Quentin was not truly defeated until the Stepford Cuckoos, utilising the powers of Cereba and Kick, blasted into the area and confronted him - Quentin admitted he staged this event to try and impress Sophie (a member of the Stepford Cuckoos), the girls expressed their disgust at Quentin and his actions before defeating him with a massive telekinetic attack. Sadly Sophie died as a result of this battle and Emma Frost was quick to condemn Quentin for his recklessness - Quentin later died due to his psychic powers overloading as a result of his abuse of the Kick drug, however due to his powerful psychic powers he is still alive on a "higher plane" of existence.

Powers
Quentin is an Omega-Level mutant - the highest category known in the Marvel universe, simply put this means Quentin is above even Xavier in strength and could achieve potentially limitless power if he so desired, he can also exist outside the physical realm in an incorporeal yet fully sentient state.
