Joe Kido: Frankly, Joe is a worrywart. But he's also very smart and studied constantly before he got sucked into Digiworld. Because he is constantly analyzing every situation, it takes Joe a long time to act or make a decision. But when he finally does do something he forgets about what might happen and can be a very brave guy. Seeing how the other kids tend to joke around and not think things all the way through, Joe takes it upon himself to be the one to always think about the consequences of the group's actions. Even though Joe may seem like a third wheel to the group--always complaining, worrying, and easily frightened--he can really come through for his friends.
Like Matt, Joe wonders exactly what kind of person he really is.
Joe has an older brother named Jim, who wants to be a doctor. Joe also has plans of being a doctor, but this is mainly because his father wants him to, not because he wants to. Jim helps the Digidestined.
25 years later:
Joe is the Digiworld's first doctor. He has a son who looks like a miniature version of Joe.
