Joe Kido (城戸 丈 Kido Jō?) is a character in the anime and manga series Digimon Adventure and Digimon Adventure 02. He is in the 7th grade. He is partnered to Gomamon. In the Japanese anime, Joe has two older brothers, named Shin and Shuu. The two brothers were treated as if they were one person, named "Jim" in the English version of the anime due to choices that were made in the dubbing process. Joe's father planned 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 (Honesty in Japan).
All his studying pays off as he is now a senior in a private middle school (junior in a private high school in the English dub). He later is busy studying for the high school entrance exams (college entrance exams in dub) while helping the others out with the spare time that he has. One of his older brothers, Shuu, is revealed to be studying folklore under Professor Takenouchi, Sora's father. He attends Wada Cram School (和田進学塾 Wada Shingakujuku?) every day after school to prepare for exams.
Michi e no Armor Shinka
Much of Joe's family history was revealed as well as how his father now accepts his son's choice to carry on their tradition or not. It was because of Joe that the D-Terminals were all mixed up & new Armor forms were introduced to fight Pukumon. Interestingly, Joe was seen dating Yolei's sister Momoe.
Revenge of Diaboromon
At the beginning of the movie, Joe was busy trying to register himself in a university of his choice (high school in the Japanese verison). Later on, he helped secure some bikes for Davis and Ken so they could get to the harbor, which was where their partners were.
