Digimon Adventure
When Mimi Tachikawa and Palmon ended up on a fragment of File Island, they encountered a Sukamon and a Chuumon that wanted a kiss from Mimi. Outside of that, they told her where Koushiro Izumi and Tentomon landed. When the Dark Masters rose to power, Sukamon and Chuumon ran, but Sukamon fell into a deep crack and died leaving Chuumon alone. Chuumon told the Digi-Destined the same thing that happened to him and sacrificed himself to protect Mimi from a knife thrown by Piedmon when MetalSeadramon, Machinedramon, and Puppetmon were also there.

Digimon 02
The same Sukamon and Chuumon tried to get Mimi to go out with them after Shurimon broke Digitamamon free of the Dark Spiral. Mimi responded to them by punching them across the lake. When Digimon started to appear in the Real World, a Sukamon and Chuumon were seen in New York.

Digimon Frontier
Some Chuumon were seen at the village near KaratsukiNumemon Mountain, the Fortune Teller Village, and the Autumn Leaf Fair (one accompanying a Sukamon).
