Koushirou "Izzy" Izumi

Hey, I like this guy! Izzy's a fourth-grader and a MAJOR computer geek. He's more comfortable around computers than people (like me ^_^). He has trouble making friends, because he'd rather go out and get information than spend time trying to understand people's feelings. Tentomon is the perfect partner for a geek like Izzy: he's an electronic bug! (But not the type of bug that's a small black magnetic disc. Not a Rita Skeeter bug either. Then again, she isn't exactly electronic. You know what I mean. If you're wondering, she's from Harry Potter.)

Izzy is adopted. His real parents died when he was very young, and he doesn't remember them. Izzy started to suspect that he was adopted in the middle of the series and this was confirmed by his parents when he returned home.
