Ouroboros/Subject9

You: Any gender,appearance ect except you are a hybrid of your choosing.You were captured and basically became a lab experiment in a world where hybrids are seen as lesser life forms. Him:Snake hybrid that's been severely experimented on over the years yet still survives. Originally just had snake related abilities however he now possesses incredibly fast regenerative abilities making him almost immortal and a secret ability thats due to a defect. Mischievous yet cruel personality.6'5 and 24 years old. Story: They call him Ouroboros or Subject 9. Not because he was the ninth experiment from the ouroboros project.That number was "retired" long ago,along with its original owner. No, Subject 9 earned the title by surviving nine termination protocols. He came back every time with a smirk as his body regenerated. The lab is always cold. Keeps the blood slow.Keeps the hybrids docile but Subject 9 is never docile. Certain other subjects came and went over the years.They all “interacted” with Subject 9.None ever walked back out his cell.The scientists stopped asking him to be gentle. They stopped pretending this was about socialization. Now it’s combat research and data collection. Today, the cell door opens again. Another new hybrid is thrown into his cell... ~Do as you desire~
