New Roulette [+]

Roulette

Alias: Roulette
Real name: Catherine Wila
Age: Catherine doen’t age. She remains as vigorous now as she was in 1973.
Gender: Female

Appearance: Catherine's appearance changes completely while she sleeps and she never looks the same twice. Apparently even her fingerprints change, so there is no way to identify Catherine physically. While sometimes her appearance is totally human, Catherine's transformations sometimes include some non-human traits. Curiously, her metamorphosis revolve around an athletic body archetype. Sometimes she can be slender and at other times a mid-weight woman, in the same way she can wake up with a voluptuous body or flat body. Likewise Catherine’s height varies the same way as her skin, hair and eyes colors.

Regardless of her appearance she is considered an attractive woman, frequently preening herself for just the right amount of bounce in her hair, or glow in her face. She wears expensive feminine clothing carefully chosen to match whatever situation she expects to be in depending on the hour of the day.

She uses a red jumpsuit made of an expandable material which adapts to the body. Additionally, the suit comes with shoulders, thighs and part of the chest reinforced with bulletproof materials. She wear long knee boots and gloves—all in the same suit’s color. She keeps more than one suit, ranging in size and heght. The suits are resistant to high and low temperatures.

Personality: Catherine usually is a lovable woman with a charming, down-to-earth attitude and a disarming sense of humor—but with those she dislikes she can be extremely acid. She’s temperamental, often showing mood swings when those she loves and protects are threatened, and in stressful situations she can have temper tantrums. She’s capable of violence and she will not hesitate to badly hurt those who deserve it. Although not shy, Catherine has a reserved space in her heart for relationships and generally tries to cultivate them as long as possible no matter the person. She has a tendency to treat an attraction to a woman as a love-at-first-sight. She used to crave fame and fortune but she knows that the days of fame are long gone.

She has adopted a deadpan attitude to all the strangeness that is her life. After decades of witnessing weird events, there is little she hasn't seen. Her greatest fear is going to sleep—meaning yet another unpredictable physical change—and she is afraid of dying during one of her comas. Sometimes, to postpone going to sleep, Catherine uses drugs. When she is far gone into amphetamines, Catherine ceases to be a friendly woman and gradually becomes a raging paranoid. She is more prone to acts of extreme violence and believes everyone is against her.

Short Biography: The Roulette is Catherine Wila, a woman who transforms every time she sleeps, each time waking up with a new appearance and new powers. Sometimes she is a powerful hero, sometimes she is nothing. Catherine began as criminal, stealing to survive as she fled from Soviet Union. Eventually, when she arrived in the United States after trying to make a living as an actress she decided to became a heroine.

Powers, Skills & Equipment: Roulette powers are unpredictable. She can sleep for weeks, sometimes months, lapsing into a sort of hibernation. While she sleeps, her body slowly transforms, and she wakes up with new powers and sometimes new appearance related to the power. Sometimes she wakes up powerful superheroine, sometimes with no power at all. When she has powers, they seem to depend on the emotional state and subconscious desires she had when she last went to sleep—and sometimes accompanied by drastic changes in her appearance. For instance, if she goes to sleep feeling cold, next time she can wake up with heat powers to compensate. If she desires to fly, she can develop flying abilities next. If she goes to sleep in a very rotten mood, she can wake up with no powers or a alien-like appearance. So, when she wakes up, Roulette usually isn't sure what her powers are this time around, and must perform several little experiments to discover them. Usually she always feature or superhuman strength, or endurance, or speed with others random powers.

While she sleeps, Roulette's body regenerates, so that she heals from any wounds, even regrowing amputated body parts. A side-effect of this regeneration is that she doesn't age. And while her sleep periods can last months, she also can stay awake for a much longer time than an ordinary human. At least one week, sometimes much longer. Catherine can't be affected by alcohol, since her metabolism while she is awake is much quicker than a normal human's. Her appetite is also superhuman, and Catherine must consume enormous quantities of food, particularly right after waking up.

She also can absorb information and knowledge while she sleeps. Catherine usually sleeps with a radio turned on, so that she wakes up with a subconscious knowledge of news and events that have transpired while she slept. She is also an expert acrobat and knows several styles of unarmed combat.

Weakness: Roulette is limited to the powers she has while awake and she can not change them freely without going through deep sleep and she can't keep the same power for two consecutive sleeps. Because of the randomness of her powers, Roulette can have super strength today and, after sleeping find that she can create bubbles or speak with butterflies. With the vast arsenal of powers also comes weaknesses. Each of the powers she randomizes sometimes has its own weaknesses—she can become a powerful human torch but she can lose her powers to the slightest rainfall or worse, she can have fire powers but without vulnerability to it, or even need to scratch the skin to generate the flame.

Full Biography:

My Hider [+]

Catherine was born in Leningrad, Soviet Russia in 1955. Her father was a scientist working in the Biopreparat, a major biological warfare agency founded in 1970. He was not only just a renowned scientist but also an American spy, he had been secretly equipped with a laboratory in the basement of his home with the goal of creating counter reagents to the Soviet’s bioweapons. Catherine's adolescence was problematic and early on she fell in love with a girl from her school. And with fear of government retaliation, she was living a double life. As Catherine held openly a relationship with a random boy from school, she also was secretly dating a girl.

In 1973, Catherine was a completely average 18-years old girl, just finishing high-school. She was making out with her secret girlfriend in her father lab when she was pushed toward one of the shelves, accidentally knocking a beaker filled with a gas. The beaker hit the ground and released a red gas that seemed harmless. Catherine's first instinct was to pick up a broom and sweep the broken glass but, to make up for the accident, her girlfriend offered to fetch the broom and as she returned, she saw Catherine body lying on the floor.

Catherine’s adolescence vanished while she slept. Nearly five weeks passed before she awoke, and he was different. She not only was half-feet higher, but looked stronger with an athletic build looking 10 years older. She was looking at herself in the bathroom mirror and wishing to not be seen by anyone when she started to fade to the point that she could see only the tiled wall in the mirror. In panic, she wished to reappear and she gradually faded in. On the same day her father brought her the bad news—it was a miracle that she had survived. Catherine’s “friend” died, her boyfriend eventually broke up with her, and her mother had requested divorce, traumatized by the event. Her father had done everything to cover up the event, but he feared the KBG. Catherine had to stop going to high school as she and her father came to an agreement that it would be better that she stayed in the house.

Three days later the KGB stormed their house, her mother had told everything about him being a spy and the “small” accident. Catherine managed to escape by becoming invisible just before seeing her father taken by the KGB. Even short of money life was a bit easier for her, she crossed to Poland by taking advantage of her invisibility and sleep disorder. It was winter when she found an abandoned shack to sleep. That was the first time she yawned. Catherine woke feeling cold, she didn’t know how long she had slept. She missed home, but she couldn’t go back—not now. She noticed she was different, her hair was black and very long, she was taller and a little more voluptuous. Before long, she found out she could raise her body temperature to the point of not only creating but projecting flames. And she used the newfound ability to hunt food as she felt an uncommon hunger that seemed to cease after 4 rabits and few fruits.

Catherine arrived in Gdansk without speaking Polish, but that didn’t stop her making money. She found that she could melt door locks by the touch and used it to steal enough money to bribe a captain to take her to Amsterdam. She continued stealing from houses to get enough money to pay two months in advance in a hotel—she was afraid to sleep in the open again. She slept in the comfort of a hotel, this time for almost a month. She woke with multifaceted eyes and dragonfly wings. She could fly, but she was a monster. The two weeks could be summed up by she sliding money under the door and receiving food through a half-open door—thankfully, she decided to take more money than needed. She slept wishing to not be seen. She woke up a week later normal—she didn’t liked the large bust she had now, though she liked her short red hair.

When she tried to explain to the hotel’s owner she found that once again she had powers. For some reason, after the man greeted Catherine and turned back, "forgetting" about her and greeting her again. The scene repeated three times until Catherine give up and leave without paying, the man didn’t care. In the street she managed to steal three wallets by simply pulling out their pocket without worrying about the outcome, when they turned around or looked away they forgot everything about her.

It took roughly one year but she finally arrived in the United States. Despite the immigration control, Catherine’s latest power gave her the ability to possess small animals, control them and appear where they were—easy to sneak around. In the United States she tried to live an ordinary life making the most of her powers. Throughout the time she lived in Los Angeles she nourished a desire to accumulate material wealth, and soon she tried her luck in the television industry. She appeared in TV shows like Star Trek, Magnum, P.I., and Hawaii Five-0. And even a TV show about superheroes saving the world called A-Team. Everyone loved the girl of a thousand faces.

Despite appearances, Catherine's life as an actress was shrouded in controversy. Her personality began to be affected by the abuse of amphetamines and working with her has become a hell. Eventually people get tired of her personality and multiple appearances and no one else would hire her. And the last one was her sexual preference which she was hiding from the press as she got involved with an actress—until then the press thought she was straight, keeping a relationship with a famous producer.

After decades making money her life changed when she saw a lady having her purse stolen. Heartfelt, she pursued and managed to catch the thief. She liked the feeling of heroism, something she had never felt before. So, she decided to become heroine. She rented three apartments in Grimmarch and bought few custom-made military suits. She took the name of Roulette, a simple tribute to the lethal game of chance.
