Ezekiel Gray is the middle of three sons of Jonah and Elizabeth Gray. Actually the eldest of a set of fraternal twins. The Gray's are old money from early investments in industry and land during the early years of the United States. Kiel, as he prefers to be called, grew up in a situation of always getting everything he wanted. Though as is often the case with both rich children and middle children, he was always an attention hog. It didn't matter if the attention was good or bad, he just needed it, and bad attention was so much easier to get. It started with acting up as a child, getting in trouble at school and causing mischief. By comparison his younger twin bother was calm and thoughtful, which easily set him up as his parents' favorite between the two of them. By his teenage years his antics degraded from something that catches the attention of the school principal to the type of behavior that instead catches the attention of the cops. Graffiti, drug possession, taking boats or cars on joy rides, the typical nonsense that gets trust fund teens printed up in the daily tabloids. Money, lawyers and plenty of settlements out of court kept him from ending up in juvie, barely.
Around fifteen his mutant genes finally started to kick into gear. He found he could control his body chemistry to a degree, and started experimenting. He even found a way to give himself a natural high, and for a budding junkie, that sort of thing was like hitting the jackpot. On his sixteenth birthday everything went awry. Lent one of the family cars for the evening, he and his twin brother decided to go meet up with a few friends for their birthday. He managed to convince his brother to let him drive, and while intoxicated on one of his endorphin highs, ends up wrapping the car around a tree, injuring himself but killing his brother. Even as he's pulled from the wreck, his body starts stitching itself back together letting his secret out of the bag, though his father pays good money to keep that bit of information inside the family. However, the blood test reveals the high levels of endorphins and the police assume this to mean drug use. He's charged with reckless driving, and this time his father does little to protect him. He ends up serving a year in juvenile detention. Upon his release, he is rather publicly disowned and disinherited by his father. At the insistence of the Xavier Institute, full guardianship of Kiel is signed over to the institute itself, which becomes his new home.
Party Animal
Kiel just likes to have fun. While it has become tempered since the accident, old habits are hard to break and he'll rarely pass up a chance for a little fun. Especially if he can skip out on work for it.
Procrastinator
Why do today what you can do tomorrow? Kiel will put off any work he doesn't want to do, indefinitely if possible.
Brave Face
Kiel is good at putting on the act of being cheerful and optimistic, even when he doesn't actually feel it himself.
Sarcastic
Oh yeah, he lets the sarcasm rip. You can almost taste it.
WWBD?
What would brother do? Kiel's guilt ridden about his brother, and will often stop to think what his brother would have done in any given situation and try to let that guide him, rather than his own instincts.
Motivations
Kiel mainly wants to learn to control his powers. Though because of the accident, he also has a strong desire to try to be a better person, though from the way he acts he has a long road ahead of him.
Goals
Kiel wants to make up for the accident that killed his brother. He wants to be a better person, and try to actually learn from his mistakes this time.
Biochemistry
All of Kiel's powers come from his body's own biochemistry. Shutting down his body's natural functions can essentially rob him of most if not all of his powers. Though it also forces any Rush he's in to degrade naturally over time instead of allowing him to come down immediately, providing at least a lingering effect.
Adrenaline Rush/Drain
Kiel can flood his body with adrenaline, unlocking physical capability some humans can only reach in the most stressful situations. At his current skill level, this Rush can double his speed and quadruple his strength. Though he can only maintain this state for about fifteen minutes before he needs to allow his body to rest for an hour. Otherwise, his body starts to tear itself apart, no longer able to keep up with the accelerated heart beat and increased muscle strain.
Or he can drain the adrenaline from his system and halt its production, allowing him to remain level-headed in situations were most people would be freaking out. Though this does dampen his flight or fight response and he's less quick to respond to danger.
Endorphin Rush/Drain
Kiel can flood his system with a sudden rush of endorphins. This dampens his ability to feel pain. The more endorphins rushing through his system the greater the pain he can ignore. The damage to his body is still present, he's just able to ignore it, but might end up damaging his body more by not knowing just how bad off he is. There's also the problem of the endorphins giving him a 'high', inhibiting his judgement.
Alternately, Kiel can empty his system completely of endorphins. While this will instantly clear his head of an endorphin high, it will also cause all his pain to come crashing back at once.
Melatonin Rush/Drain
By flooding his system with melatonin, Kiel can either calm himself down, or put himself completely to sleep. This also has the added benefit of slowing his metabolic rate, and helping to speed along the healing processes.
Conversely, Kiel can completely drain his system of Melatonin, keeping himself perfectly awake and not the least bit drowsy. However, his body still needs sleep, and while he may feel awake, his body will start to shut down if he goes for more than three days without rest.
Healing Factor
Kiel has a increased healing factor. While not at the level of some, he can heal at a fast enough rate that most bruises will disappear in an hour, cuts in a day, and major bodily injury in just about a week with enough rest. He could even potentially regrow lost body parts if given enough time and rest. This also allows him to survive injuries that may kill others, as his body can quickly stem bleeding and repair nerve damage. May also potentially slow his aging to a degree.
Xavier's Institute
Kiel is a student, and also the legal ward of the Xavier Institute. He has access to resources and faculty similar to any student of his age and skill level.
Known
Kiel is known in certain circles. High society and pop culture circles. While he may not always be looked favorably upon, at least his is a name people will recognize.
Quick Learner
Kiel is quick on the uptake and smart enough to grasp most concepts quickly. Motivation on the other hand is a completely different matter.
Socializing
Kiel knows how to schmooze and rub elbows. He's perfectly at home in a night club or at a high society gala. He's been trained in etiquette and knows how to act in a variety of situations.
Streetwise
Time in juvie and his delinquent antics at least taught him how to act on the street. True, he didn't grow up on the rough streets, but he knows enough to get by, and where the scum of society likes to hangout, like dealers and fences.
Technology
Like most of his generation, Kiel is skilled at using a wide variety of technologies. He may not be a hacker, but it's rare for him to come across a piece of equipment he doesn't know how to use or couldn't figure out with a litte thought.
Larceny
Not a master thief, but still Kiel knows how to pick locks and spot security systems. Hotwiring cars and shoplifting are also well within his areas of knowledge. Those skills only got better with a few pointers from the other teens in Juvie lockup.
Brawling
At least he knows how to throw a punch. He doesn't have any offical combat training nor does he know any martial arts. Still he's enough that he could at least stand his ground if fists started flying.
Minor
Kiel is under 18 and still a minor. He can't do fun things like vote and buy lottery tickets.
Guilty Conscience
Kiel blames himself for the death of his twin brother, and bringing it up is a good way to either set him off or shatter his self-esteem, depending on his current mood.
Nervous Behind the Wheel
Kiel hasn't driven any form of vehicle since the accident, and for now he's content to keep it that way. Just thinking about driving gets him twisted up in knots that even his powers can do little to diminish.
Publicly Disowned
Kiel has been rather publicly and bluntly disowned and disinherited by his family. The Gray family has a lot of clout, and he's officially on their list of Persona Non Grata. Not only does he find the situation humiliating and distressing, but having one's own father as an enemy can cause serious damage in the long run.
Rap Sheet
Kiel's actually seen his fair share of arrests. While most of the charges were dropped or settled out of court, there is the instance of him spending a year in juvenille detention. Includes: vandalism, destruction of property, drug possession, driving under the influence, possession of stolen goods and disturbing the peace. And, of course, one count of vehicular manslaughter - term served.
Daddy Dearest
Kiel has not managed to endear himself to his father. In fact, at this point they're pretty much enemies, and his father has power. Jonah Gray is wealthy, on the board of several companies, and a member of the Hellfire Club (though not of the Inner Circle). While content to stay out of each others' ways for now, a clash between them could be devastating.
