never seen, but the silhouettes of their heads are seen in those globes. They have their birthdays celebrated each month on a day called "Cake Day" for any foot soldiers who have their birthday in that month. Copperhead (voiced by Tom Kenny) - Half-man, half-machine. Unlike Glowface, he never stays in one place for long. It was never actually revealed that he is part of S.N.A.F.U. or not, but he is "The most evil of all evil spies". He has power over magnetism (like that of Magneto in X-Men), but he runs on a large battery in his back. Minor Kimla Meeks (voiced by Ashley Johnson) is Tuesday's 1st friend appeared in "A Truman Scorned", "Theater of War" and "License to Slumber". She is a huge fan of science fiction and is also very knowledgeable about sci-fi movies, comics, etc. Kimla also seems to be somewhat naive as she didn't notice Truman's crush on her and that the X's are spies despite her being presented with proof. She appears to have started talking to Tuesday more after their slumber party as they worked together on a school project later in "A Truman Scorned." A running joke throughout the series involves Kimla's "intergalactic chanting." Skipper Swenson (voiced by Lindsay Sloane) is Tuesday's 2nd friend appeared in "License to Slumber". Skipper is generally stuck-up and is rude to Tuesday. She doesn't like Tuesday very much and only came to her slumber party because Trudy apparently promised to pay her fifty dollars. Skipper is very popular and is also shown to have an interest in beauty and boys. Annasthesia Montiho (voiced by Soleil Moon Frye) is Tuesday's 3rd friend appeared in "License To Slumber". She is a goth girl and notices the strange occurrences at Tuesday's slumber party. She also likes to talk about boys. Wally (voiced by Tom Kenny) is a friendly neighbor of the X's. He is a devoted father with a wife and child. Wally is very nice to the X's when ever he sees them. While he's suspicious of the X's at times, he never catches on that they are spies. Wally first appeared in "Mr. Fix It," and has made appearances in "Mock Tutors," "Y's Up," and "Live and Let Diaper." Although his name is never mentioned in the series, it is listed as Wally in the credits of episodes that featured him. Mother (voiced by April Winchell)
