Guardians of the Galaxy 1.

Kathrine Malus never thought anything of life. She was just another person trying to get through living as a Ravager. She preferred not to go by the term 'petty thief'. She thought of it more as... Taking things from people that don't deserve them. Ever since she was taken from Terra by Yondu to become a Ravager she has been beside Peter Quill. He goes by 'Star-Lord'. He always tried to give her a 'menacing' nickname but she just refused. He did it anyway and called her 'Serpent'. She hated it. Yondu used to say the only reason he kept her around was that she was a good liar and could sneak around like a snake.
