Archelomon

Archelomon is the Armor Digivolved form of Wormmon through the Digi-Egg of Reliability. He resembles an Archelon, a giant prehistoric turtle.

The Adventurer's Battle
An Archelomon was among the Digimon in VP Labs when Takato Matsuki and his cousin Kai ventured there to rescue Minami. It lunged at them as they emerged from the lab's tide pool, but Growlmon easily destroyed it in mid-air. Shortly thereafter, another Archelomon was seen in the void between Earth and the Digital World. It was destroyed by Omnimon.
