Darius once had it all, wealth, fame, fortune. He never feared the rumors of mutants and how disease spread. By the time he had learned it was too late. A fan attacked him, an infected one, he show have died, but he didn't he was saved although you could say Darius did in fact die that day, only his body remained.
Every memory, every frigment that made him Darius faded as his body changed. The thrill of the hunt, the bloodlust, the urges. He hated them. His family gave him up, this was nit there son anymore, this was a monster.
He escaped from the lab he was held in, roaming the streets, killing those like him, he hated them, how they ruined the lives of the healthy. Even if he didn't remember his own life before his infection, he refused to let the innocents suffer.
He was hunted like a dog, dangerous, feral. That's what they called him. When he was caught he figured his life was over, but one human, a young woman, treated him like a person, not some feral beast. When she spoke, he listened, what she said he would do, he didn't know why, but he did. The others called him tamed, thay called him her pet. She would correct them, tell them he was a person too, but they didn't listen. He didn't care.
Now he was living with her, she said it was for research but he new that was just an excuse to get him out of the lab. She called him Darius, said that was his name, he wouldn't know. He can't remember much, but he would take her word for it.
