Ulrich Stern is a character on Team Lyoko from the French animated television series Code Lyoko. His romantic love interest is Yumi, whom he falls in love with during the series and often finds himself dealing with his romantic feelings for her.

Personality and Characteristics

Ulrich is the introvert of the group. He doesn't say much about his personal life and is evasive when someone asks him about himself or his family. He seems to have trouble opening up to people

and hides his feelings in order to use them all the more explosively in action. Whenever someone is in danger, his feelings tend to surface very quickly. The first example of this is in the episodeKiller Music, when Odd is sent to the hospital and later on slips into a coma and Ulrich blames himself for not being there when Odd had needed him. A similar situation occurs in the second season episode Cold War, when Yumi is trapped under a fallen tree during a blizzard and he cries as he tells her that he needs her while holding her, after several failed attempts to free her, and screams when she appears to have died.

Though on the outside, Ulrich appears to be fairly emotionally strong, he deals with hidden issues few could understand. One cause of this are his parents, who are very hard to please and have high expectations of their son. In Zero Gravity Zone, Jeremie berates Ulrich for going to the soccer game instead of helping to fight X.A.N.A., yet Ulrich does not retaliate or change his mind. Odd explains his reasoning after he leaves the room that Ulrich wants to go because he doesn't want to disappoint his parents, especially his perfectionist father who is a businessman. This is later proven in Final Round, when Ulrich's father appears and berates him for his failing performance in school (and even insults his friends, accusing them of being a bad influence on him, despite having never met them). A clear example of his bad grades is when he receives a D- on a science test in Nobody in Particular and receives a F+ on a test in another episode (the plus being added "so he can do worse on another") despite having tried his sincere hardest to get a passing grade. 

In the second season episode Vertigo, it is discovered that Ulrich has vertigo, which is a chemical disorder that causes dizziness. He shows signs of it when attempting to climb a rock wall, which reveals the condition to his friends. It hasn't seemed to affect him before this point, except in the prequels, when he hesitates to slide down the ropes to the factory floor. Having vertigo does not seem to be a hindrance on Ulrich when on Lyoko, with the notable exception of the episode Bad Connection.
