Roachmon

Roachmon is an Insectoid Digimon whose names and design are derived from the cockroach (ゴキブリ Gokiburi?). Its black-lustered body is the very cockroach that everyone hates. It moves around stealthily and nimbly, and runs away even faster. Although you can hardly expect it to have offensive or defensive ability, because of its immeasurable stamina, it shows itself at its best when it comes to a protracted war.

Digimon Adventure 02
The Roachmon Brothers (sisters in the Latin American dub) were under the control of the Digimon Emperor's Dark Rings in the Night Forest. After arguing with what to do first, they chased after Mimi Tachikawa, Yolei Inoue, Hawkmon and Palmon while bombarding them with garbage until Hawkmon armor digivolved to Halsemon to fight them. Mimi and Palmon blinded them with a search light enough for them to fly into the Control Spire, cracking it. Palmon digivolved to Togemon and helped Halsemon destroy the Control Spire. After that, the last thing the Roachmon Brothers remembered was that they were arguing with each other (In the Japanese version, the Roachmon Brothers were in perfect accord with each other. But once the Dark Rings were removed, it turned out the two never get along).

Some Roachmon were under the control of Arukenimon's flute at the Giga House. ExVeemon washed them down the drain right before the Kunemon attacked

Role in Ultima
In Ultima, Roachmon are basic Grunt-class D-Minions in the Jungle Trooper division of the Organization's D-Minion Army. Their primary function is to zerg rush into enemy camps and scatter virus-infected trash so as to weaken the troops severely so as not to fight back later.

They are a natural digivolution of Kunemon and Tentomon through Junk Evolution, and will digivolve further into Garbagemon either with or without a DNA-digivolution with Numemon.
