Eri Karan is a major heroine in Digimon Universe: Appli Monsters. Her Digimon partner is Dokamon.
She is voiced by Umeka Shōji.
Eri appears as a teenage girl with fair skin, long, wavy pink hair in several shades tied up with yellow hairties into of two ponytails, and blue eyes. She dons a blue jacket over a bare midriff white shirt and a pink tie. She also wears jean shorts, black knee-high socks with pink trims, and aqua-and-hot pink sneakers.
At the first glance, Eri is described as a energetic person with a unique personality who is very agile. However, in truth, she is very kind and a bit prone to loneliness. She is an active member of the idol group Appliyama 470.
Eri and others are lured into an ambush by Hackmon and his Appli Driver Rei Katsura, who challenge them for a fight.
Haru, Eri, Torajirou and Rei are attacked by the Ultimate 4, a team of powerful Appmon under Leviathan's that easily destroy both their buddies and AppliDrives. Just as they are about to be killed as well, Yujin and Shutmon appear and face the enemies by themselves to help them escape.
Eri and the others reunite with their Appmons, who do not remember them at all, and are sent to a journey to restore their buddies' memories. In the occasion, they not only reconnect with Hackmon and the others, but obtain each one their own AppliDrive DUO.
