Kari

Kari May have came a little later in the season 1 episodes, but many love her!  She is sweet, caring, innocent and is always putting others before herself!  She is Tai's younger sister and is in the first Digimon movie starring with Tai and Koromon.  She seems to have a weird connection with an outside force in the digiworld that no one can explain.  Kari also continues to be a main character in season 2, while Mimi and Sora are not.

Her Digimon are as follows:
In Training- Nyromom
Rookie- Salamon
Champion- Gatomon
Ultimate- Angewomon
Mega- POSSIBLY(not for sure!) Holydramon
