Odd's blond hair has a purple spot and is worn up in a spike. On Lyoko, he is clothed like a cat, with a tail and clawed gloves that shoot "laser arrows." In season 1 he had a precognitive power named "Future Flash", but it was deleted before season 2 and is replaced by his defensive ability to create a purple energy shield by crossing his arms in front of his body, covering half of his body. Another one of Odd's abilities is being able to use his claws to climb on walls like a cat. Ulrich Stern Voiced by: Marie-Line Landerwijn (French); Barbara Weber-Scaff (English) A more reserved member of the group, Ulrich has a hard time sharing his feelings. His parents pressure him to achieve well in school, but he has difficulty learning and living up to their expectations. In his off-time, he practices Pencak silat with Yumi, whom he has a crush on. He suffers from vertigo, which makes it hard to participate in activities such as rock climbing. Due to his many activities, Ulrich has a rather muscular build, thus many girls (particularly Sissi) consider him to be extremely handsome. On Lyoko, he wears a yellow and brown outfit inspired by Japanese samurai. His main weapon is a katana, and can dual wield them. His "Supersprint" ability allows him to dash at high speed, and his "Triplicate" power lets him create two clones of himself. He can combine these abilities in a technique called "Triangulate," using his clones to form a triangle around an enemy and ambush it from behind when it is distracted. Yumi Ishiyama Voiced by: Géraldine Frippiat (French); Mirabelle Kirkland (English) A fairly reserved student who lives near and attends Kadic. She is the oldest of the group. She is of Japanese descent and has one younger brother, Hiroki. Because of her parents and culture, she must maintain good grades and observe family values. At home, she generally has to deal with marital issues between her parents. She is a friend of William Dunbar, who transferred to Kadic during season 2. She practices pencak silat with Ulrich, whom she has a crush on, though it's not as obvious as Ulrich's crush on her. She always wears black and has enough basic knowledge of the Supercomputer to operate it in Jeremy and Aelita's absence. On Lyoko, Yumi is dressed in a geisha-inspired outfit with
