Alright, have a look and tell me what you think. Couldn't really find a good picture, though.

[hider=Duke][b]Name:[/b] Marmaduke Cashmere

[b]Nickname(s):[/b] Duke, sometimes referred to as Rat Bastard

[b]Age:[/b] 18

[b]Grade:[/b] Mephisto's, 3rd year

[b]Appearance:[/b] Long, unkempt black hair, mostly vacant brown eyes. Looks quite unreliable at first glance. Wears a heavily worn second-hand uniform, but sports noticeably expensive accessories. He's quite tall but somewhat thin, it seems like you could push him over without much effort.

[hider=Biography] Marmaduke (or Duke, as he likes to be called) was born to a poor home, to a single mother in a bad neighbourhood. His father was a far-gone fling of his mother's, so they were left to fend for themselves. It was rough, and they didn't always have the best relationship. His mother was convinced that he would do great things, but for young Duke, that was difficult to see. He had only average grades, even in the poorer schools he attended, and he wasn't any particular standout in sports either. He didn't have any kind of charisma, merely a penchant for getting caught in mischief. Given the circumstances he naturally gravitated towards the bad folk, and whether he was at fault or not, it seemed like he would always get drawn into trouble. Still, his mother insisted that he believe in his bloodline, though he preferred to rely on himself. He knew they were balancing on the knife's edge, and sooner or later, things would tip. And they did.

One day, on coming home, Duke discovered that his mother had been hospitalised. If his circumstances were tight before, they were downright asphyxiating now. It became a challenge of balancing school and work, scraping just enough money to pay bills. He had little time for sleep or food, and it took a toll on his health. He began to entertain darker thoughts as he spiralled downwards, wishing for a way out, wishing for a miracle, wishing for his father, perhaps. But, at the end of the day, he knew that there was no such thing as a free lunch. And at his lowest point, it arrived. One day, as if out of nowhere, a red imp appeared. It told him that it was a servant of his father, that it was there to teach him how to use his power, how to unlock his bloodline. If he chose to, he could have it all. Riches, fame, power, anything was possible. At that moment, the only thing he needed was money, and lots of it. He's not sure what happened next. He blacked out and then woke up in his bed, surrounded by a small pile of money. He was happy for the first time in a while. He rushed over to the hospital to make a payment and to tell his mother about the good turn they had received. Unfortunately, by the time he arrived, she was already dead.

Bereft of his purpose, Duke was stunned for a while. He tried spending his "hard earned" money in hedonestic ways, but nothing seemed to fill the hole inside. The imp had told him clearly, that there would be a price to pay. If he knew what it had been before, he wondered if he still would've taken it. Listlessly he drifted through his life, school, work, until it came time to go to high school. He decided to enrol at Mephisto's School for the Wickedly Inclined, because if anyone was Wickedly Inclined, it would probaby Duke. He found that he fit right in to Mephisto's and soon garnered some infamy for himself inside and outside of the ring. Outside he set up and participated in paid bets, winning and losing large amounts of money. Inside the ring he was known as a wildly inconsistent fighter, winning fights against people he shouldn't have, and losing fights that should've been easy to win. His track record was that of a fairly typical Mephisto daredevil, but he was just having a good time. It was the closest he had felt to being alive ever since that day.[/hider]
[hider=Powers]
[b]Core: [color=palegreen]Hellfire[/color][/b]
A "gift" left to him by his father. By using his blood as a medium, Duke is able to summon sickly green flames straight from hell. The flames sap life from those afflicted, plundering it for the controller of the flames and allowing Duke to imbue himself or others with life force, healing wounds and bolstering physical performance. Of course, this power is not without a price. If it can't sap the life force of his enemies then the green flame will sup from Duke's own reserves. Once formed, the hellfire can take many forms. Balls of fire, bolts of fire, flaming weapons, and more. Being afflicted with the fire drains the victim's stamina, but has no effect on non-living entities. Of course, there's a limit to the power one person can summon. Which is where his imp friend comes into play...

[b]Ability 1: [color=palegreen]Spin the Wheel[/color][/b]
Duke is psychically linked to an imp-like creature (dressed like a gameshow host) which he can summon at will. Formally known as [color=red][b]Morton the Red Devil[/b][/color], or just Mort. On summoning them, the imp creates a giant wheel with various outcomes on it, both good and bad. Good outcomes can multiply the power of Duke's hellfire, whereas bad outcomes can divide it. The result is random, and not even Mortimer knows what the wheel will stop at. Mortimer can be summoned again consecutively with an increasing large tax of life force, so repeated spins are inadvisable. The effects of this ability last for roughly half an hour.

[b]Ability 2: [color=palegreen]Double or Nothing[/color][/b]
This ability can only be activated by telling Mortimer to do so while the wheel is spun. It doubles the eventual reward of the spin, regardless of whether or not the result was good or bad.

[b]Ability 2: [color=palegreen]Blood Sacrifice[/color][/b]
While the wheel is spun, Duke can spend a significant amount of life to force the wheel to land on a good result. The amount of life spent is always more than the reward, proving it to be an inefficient use of his powers, unless he has a good supply of lifeforce ready.

[b]Relationships:[/b] No particularly close relationships, but most Mephisto students know of him, and some outside of Mephisto know of him as well.
