Ulrich Stern
Ulrich Stern (voiced by Barbara Weber-Scaff) is the silently-strong introvert of the group, unwilling to talk about himself unless prodded considerably. Along with Odd, he is often the first to suggest taking immediate action against Xana.
Ulrich has brown hair. In the first three seasons, he wears a light green shirt with a vest over it and cargo pants, all varying shades of green, and white shoes. In the fourth season, his vest is replaced by a black shirt and army jacket, his white shoes are replaced with black shoes, and his cargo pants are replaced with blue jeans. His night clothes are green boxers/boxer-briefs with a white sleeveless shirt. For the 1st and 2nd season he is 13-years-old and in 8th grade. In the 3rd and 4th he is 14 and in 9th grade
Ulrich doesn't say much about his personal life and is evasive when someone asks him about himself or his family. His parents, his father in particular, are very hard to please and have high expectations for their son. He also has trouble expressing his feelings, mainly where Yumi Ishiyama is concerned. A common theme in the series is Ulrich only admitting to something after a brush with death or an otherwise dire scenario. In addition to his troubles with Yumi, Ulrich has to deal with Sissi's affections. Due to her being the daughter of the principal, he is often forced into humoring her in order to get something from her father.
Ulrich sees William Dunbar as his rival in their race for the affection of Yumi and can get often very jealous at him.
Ulrich's Lyoko attire is modeled after a samurai, minus armor, and he carries a sword. An Oni is drawn on his back and the clothing is largely colored yellow and black. He gets a new outfit in the fourth season, which trades his more loose-fitting clothes for a tighter yellow and brown body suit (similar to William's). A device on his back is traded for his sword sheath, which, in addition to carrying two swords, hides the blades when they're not in use. For travel, he uses a one-wheeled motorcycle called the Overbike, which is also capable of flight.
Ulrich's two swords allow him to cut through monsters with ease or deflect enemy laser fire. His speed on Lyoko is enhanced, such that he can deflect even rapid laser fire with relative ease and run faster than most monsters. An additional boost to his speed can be gained through a super-speed running ability (called Supersprint), which can be use to easily traverse long distances, and even cross the surface of water. He can create two clones of himself to aid in battle (called Triplicate), each of which can take one hit before being destroyed. He can bring these clones back together into him (called Fusion). He can also summon his clones to make a triangle around his enemy, (called Triangulate) then attack it when least expected. Both he and Yumi are practitioners of Pencak Silat.
