Tuesday X is the X's teenage daughter and missions investigator. She is 16 years old. Tuesday is the most normal of the team, despite her rather extreme punk-rock garb and frequently changing hair-color, and is also the most knowledgable of "real-world" behavior, which the other family members either misunderstand or ignore outright. She definitely takes after her mother in savagery and fighting skills, but at heart Tuesday is a genuine teenager who wants to do other things besides spy missions with her family. She easily gets annoyed with Truman and is not good at talking with other girls her age. Currently, Tuesday is involved in an on-again-off-again relationship with Glowface's nephew Brandan.
