Kari Kamiya (Adventure)
In the first season of Digimon, there were seven DigiDestined that got transported to the Digital World. But lo and behold, there was a secret eighth one who had yet to discover their destiny, and that person turned out to be Tai’s younger sister Kari. She’d already come into contact with Digimon over the course of the season before, but it wasn’t until she took Gatomon home with her and Wizardmon showed up for them both that the younger Kamiya got her Digivice. With Gatomon as her partner, she was able to help the others save the Digital World and defeat Myotismon, and later Apocalymon.
She and TK return in season two as main characters, older and joined by Davis, Cody, and Ken. Aside from the growth spurt that comes with being older, nothing has really changed about her, including her kindness and love for others. It’s the only way she could put up with Davis’ admittedly obnoxious personality, and without it, Gatomon would’ve gutted her when they first met. Maybe moreso than Mimi, love and kindness is just an integral part of who she is, so much that her dream is that humans and Digimon live with each other in harmony.
