Joe Kido (城戸 丈 Kido Jō?, lit. "Jo Kido") 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).
Joe has become the first Doctor for Digimon, and taking along with the job, all the complications that occur because of it (like his patients eating the tongue depressors). In a way his family's tradition continues and his son (who very closely resembles him, and has a Bukamon) may carry it out as well. His second eldest brother, Shuu, appears to be working with Izzy and Sora's father to study the Digital World. He has Daisuke Niwa as he Digi-Destined apprentice.
