Tylomon

Tylomon is a Sea Animal Digimon. It armor-digivolved through the power of the "Digi-Egg of Reliability". Because of its unique form, it holds the alias of "Jet Plane of the Deep" and has a fast moving speed underwater, even contending for first place with MetalSeadramon. Due to its extremely ferocious personality, those that enter its territory are attacked even if the opponent is larger than itself. It is able to distinguish scents that are 1 km away from it while underwater.

Digimon Tamers: Battle of Adventurers
Tylomon appeared during Mephistomon's time in the Real World. It was among the Digimon sent to capture Minami Uehara so she could be used to force the location of the V-Pet vaccine program from her father. The Tylomon chased after her as she fled the island base of VP Labs and the pursuit interrupted a quiet fishing trip that Takato Matsuki, his cousin Kai and Guilmon were on. Guilmon attacked the Tylomon and they disappeared beneath the sea but Guilmon emerged through the waves a short time later, the victor showing that Tylomon was destroyed.
