Jeremie's room is located on the second floor of the dormitory building, close to Odd and Ulrich's room. It is often cluttered, mostly with robot or computer parts. It also contains his bed, wardrobe, shelves, a massive computer (with a connection to the Factory supercomputer) which he uses in their fight against X.A.N.A., and a poster of Einstein over Jeremie's bed. Jeremie briefly shares his room with his cousin Patrick in "Cousins Once Removed." The Lyoko Warriors often hang out in Jeremie's room. Occasionally, whenever one of the warriors wants to talk to him in private, they meet here.X.A.N.A. Awakens it is implied that Ulrich shared this room with another student, but it is unknown who he was. Their room is fairly simple, with just two beds, wardrobes and a desk. There are a number of posters on the walls, including a Pencak Silat poster which hangs over Ulrich's bed. Odd's dog, Kiwi, lives in the bottom drawer of his wardrobe, where Odd hides him from staff. It's unclear who uses which desk. On Ulrich's poster, the flags of Turkey, the United Arab Emirates, Japan, Paraguay, and China can be seen.
During her first few days at Kadic, Aelita stayed with Yumi's family. However, after she was properly enrolled she got her own room in the dormitory building. Aelita's room is on the same floor as Sissi's. It is quite a small room compared to some of the others, with a bed on one side and a wardrobe and desk on the other. Aelita's room isn't seen very often since she spends more time with Jeremie and the others than she does there, once even being caught on the computer in Jeremie's room after bedtime by Jim. It also has a computer that she used to with her father as seen in Distant Memory. The Lyoko Warriors periodically hang out in this room.
Sissi has her own room at the Kadic Academy dormitories. Her room is first seen in Teddygozilla when she is getting ready for the dance. Her room is also seen briefly in Saint Valentine's Day, A Great Day and in Log Book, when Yumi finds Sissi's diary hidden in a teddy bear. It contains a bed, various posters, a computer, a pink circular rug next to her bed, a closet full of designer clothes, and a dressing table with a vanity mirror and lots of cosmetics and make-up supplies. There is a pillow on her bed shaped like a heart with arms; it is where she keeps her diary (as shown in 'Log Book').
William's RoomSince William's arrival at Kadic in Season 2, the room was not seen at all until it made its first appearance in Dog Day Afternoon. It made another appearance in A Lack of Goodwill. In episode Fight to the Finish, it is shown that William's Dorm is very close to Jeremie's Dorm. The room is very messy, much like a typical teenage boy's room. He has a computer; and, surprisingly, some paint, a canvas stand, and a guitar deducing him to be a painter and a good guitarist. William does not share his room with any other student. His room was also used by his clone upon his disappearance.
OthersMilly and Tamiya both share a room together, although their room is seen only once in Teddygozilla and Just in Time. Jim also has his own room, located on the ground floor of the dormitory building, the walls of which are seen to be covered in posters of famous athletes; additionally, there is a punching bag, boxing gloves, various weights and barbells, and a boom box. Jim can be seen working out in his Dorm room in the episode Rock Bottom?.
