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. Truman X (voiced by Jansen Panettiere) is Mr. and Mrs. X's son and technology expert. Truman is the smartest of all the X's. His radiation "experiments" cause so many "meltdowns" that the local Decontamination Squad are on a first name basis with the "X"s. The enfant terrible of the "X"s, Truman can sometimes be a nuisance and make trouble. Truman is 10 years old. Rex X (vocal effects provided by Dee Bradley Baker) is Truman's dog he got on his 9th birthday from Sasquatch. Rex was meant to kill Truman with Sasquatch controlling Rex with his mind-controlling roar, but after Truman wouldn't fight him because he thought he would finally have the perfect birthday with him and Truman told about all the good times they had. After those words, Rex broke free from the mind control and also all the other animals. Later, Rex became an honorary member for SUPERIOR. His first appearance was in "Boy's Best Fiend" and has since appeared in other episodes such as "To Err Is Truman". Home Base (voiced by Stephen Root) describes itself in the title sequence of The X's as "the house they live in", but Home Base is most likely the name for the computerized brain that runs the functions of their house (neither Mr. X nor Mrs. X appear to be competent about household chores, though Mr. X can mow the grass). Home Base serves as advisor, SUPERIOR contact and mission alert for the X's, and can be contacted from the X-Jet. It also serves as the (somewhat beleaguered) voice of reason in the family. Seen from above, Home Base is shaped like an X. He is visually similar to HAL 9000 from Stanley Kubrick's 2001: A Space Odyssey. Villains S.N.A.F.U. – Short for Society of Nefarious and Felonious Undertakings, S.N.A.F.U. is an evil organization that the X's fight. Glowface (voiced by Chris Hardwick) is the X's' archenemy, the leader of S.N.A.F.U., and the main villain of the series. Glowface's head is encased in a glass
