Pipismon

Pipismon is the Armor Digivolved form of Patamon through the Digi-Egg of Love. His name comes from pipistrellus abramus, the Japanese house bat. They are known to mimic someone's speech and their powers are greatest in the dark.

Digimon Tamers: Battle of Adventurers
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 him 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 by Growlmon, along with Ponchomon and Sepikmon.
