Joe Kido

Joe Kido (城戸 丈) is a character in the anime and manga series Digimon Adventure and Digimon Adventure 02. He is in the sixth grade. He is partnered to Gomamon. In the Japanese anime, Joe has two older brothers, named Shuu and Shin. The two brothers "became" one brother named Jim in the English anime due to mistakes that were made in the dubbing process. Joe's father planed on the boys to each become a doctor, a tradition which had existed since the Edo period. Joe is the bearer of the Crest of Reliability and his respective colour is teal and element is water. (Sincerity in Japan).
