Millie is a very lively and cheerful individual. Often with a smile on her face and rarely standing still, she is a clear extrovert and is not afraid to speak her mind. This is regardless to whether it's expressing her excitement or flipping off a co-worker. As the bruiser for I.M.P and as an assassin, she is shown to enjoy her job. Her meek exterior appearance belies a tough and very violent skillset. This is highlighted during a conversation Millie once had with her mother and sister. According to Moxxie, she is aggressive in "the sack" as well as her job. In "Murder Family", she appeared to be very unsympathetic about killing a possibly innocent target, only caring if it was what their client wants, showcasing her dedication to her work, and her ruthlessness. However, in "Bad Reputation," in a flashback, she was genuinely horrified at seeing innocent farmers at Stiffwood farm get slaughtered during a mission. This implies that she may only have no issue with killing innocent humans
