At a glance, Joe appears to be a nervous wreck, panicking over little things (in the dub, he has a tendency to feel "allergic" to everything around him). This stems from Joe's strong sense of responsibility, in addition to being the oldest of the group. He acts as the voice of reason and tries, often without success, to steer the other DigiDestined away from danger and tries to find a safer way. His "safety first" attitude is often the source of teasing from others specially Gomamon, who teases him the most but all the DigiDestined respect and trust Joe for being reliable. His reliability is shown whenever Joe will not hesitate to put his life over the others (for example, he saves T.K. from drowning). Teasing aside, the DigiDestined respect and trust Joe because they know he can be relied on to be selfless and brave when problems arise. During the time the Infected Digimon start showing up, Joe is struggling in school, leading him to focus on studying more than on assisting the team. This anxiety builds until Joe is confronted by Gomamon, who, feeling unable to help, leaves Joe, causing Joe to reevaluate his priorities and make up with Gomamon.

Joe is very intelligent and has practical knowledge of first aid and astronomy. He is also extremely clumsy, and often finds himself falling on his face or dropping things. He eventually becomes much more mellow and level-headed, though the clumsiness remains. Joe is the youngest brother of his family, who follow a strong tradition of being doctors.

Holder of the Crest of Reliability.

Bryan Previte did a nice job on Joe, so I'm looking forward for his emulation on Joe. But I'm OK with some imitations akin to the late Michael Lindsay or the more recent Robbie Daymond.
