Tucker and Trudy's teenage daughter and missions investigator. Tuesday is the most normal of the team, despite her rather extreme punk-rock garb and frequently changing hair-color. She is also the most knowledgeable 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 for making fun of the size of her huge butt, despite that, she behaves like a caring sister like in the episode "You Only Sneeze Twice" when Truman's look-alike robot was about to explode, she became worried and in another episode "From Crusha With Love" she guided Truman with his date by advising him. In the episode “X Take A Holiday” it's revealed that Tuesday is 16-years-old.
