Bio:
Ulrich Stern is 13. Unlike his best friend and roommate, Odd, he is well known for being somewhat introverted, in that he seems to have trouble opening up to people. Though on the outside he appears to be fairly emotionally strong, many would argue that he's probably dealing with some hidden issues underneath that no one knows about. One cause of this could be his parents, who, as we learned in "Zero Gravity Zone," are very hard to please.

On Earth, Ulrich wears olive green baggy pants and a dark yellowish-green top with a green jacket over it. In Lyoko, he wears a samurai-like outfit which is yellow and brown. He fights with a Katana, and also has the power to create clones of himself which attack enemies along side him. (Though they usually die fairily quickly.)

Something that Ulrich is probably most noteable for (especially in the fangirl community) is his relationship with Yumi. Though it's obvious that they like each other, they technically aren't an item. Yumi, however, is not the only person interested in him; Tamiya , Milly , Emily , and Sissi also like him quite a bit. Sissi is the most noteable of the bunch because she's the most persistant in trying to get him to like her back.

Notes:

• The big Ulrich-Yumi almost kiss occurred in "Routine."
• Ulrich keeps a diary. (We learned this in "Log Book".)
• Ulrich is on the soccer team ar Kadic.
• In Odd's band, Ulrich plays the electric keyboard.
