Pipismon

Pipismon is the Armor Digivolved form of Patamon through the Digi-Egg of Love. They are known to mimic someone's speech and they resemble bats.

The Adventurer's Battle
Pipismon was one of the Digimon who invaded the island base of VP Labs, and held company president Ryuuji Tamashiro and programmer Takehito Uehara captive, threatening Uehara’s daughter, Minami, to make Uehara reveal the location of the V-Pet vaccine program. When Seasarmon and Growlmon burst into the complex to free Minami, Pipismon was destroyed with one Pyro Blaster shot, along with Ponchomon and Sepikmon.

Digimon Frontier
A bunch of Pipismon were seen in the Dark Continent and mimicked the speech of the Legendary Warriors. Some were destroyed and had their Fractal Codes absorbed by Arbormon.
