Nemesis is a sadistic, mischievous, domineering and mysterious transformation weapon - a living artificial being with shape-shifting capabilities. She believes that a transformation weapon's only purpose for living is killing. Nemesis has an erotic side to her, and has claimed that she does not have full control over this side of her personality. She is eerily optimistic and apathetic at all times, and whether things go her way or not, she shows little negative feelings for any reason. Nemesis seems to like Japanese culture. She replaced her main outfit with a summer yukata, she likes dango (meatballs), and uses old Japanese terms to call people such as "hime" (princess) and "geboku" (servant).
