Bio: Kari has a heart condition known as tachycardia, or rapid heart beat, meaning her heart beats faster than normal and too much activity is dangerous for her. Because she also has asthma, her heart works twice as hard to pump blood, causing her to become tired very quickly and if she is not careful she can faint from exhaustion or worse. This, for some reason, doesn't seem to effect her on Lyoko.
Kari lived with her parents and older brother until she was 10. Her father's business associate stole money from the company he worked for and sent it under. Her parents were forced to send her to live with her grandparents while they tried to rebuild the company, and her brother went to a boarding school in America (he got a full scholarship). Kari is bitter because of how her lifestyle changed so much. What makes her the most unhappy was that her parents had scheduled a surgery to fix her heart, but after the incident occurred they no longer had the money for it.
Kari has been living with her grandparents ever since then. She has not seen her parents since she was 12, and has not seen her brother since a year ago, before he went to college.
Kari is a gamer-girl, and enjoys playing online games and with her gameboy, even though she only has 3 games for it. She also likes to draw sketches in her notebook.
(edit) Personality: Kari seems cold, quiet, and distant most of the time. She hates it when people pity her because of her health problems or her family situation.
