AncientTroiamon

AncientTroiamon is an Ancient Plant Digimon whose name and design are derived from "Ancient" and the mythological Trojan Horse. It possesses the attribute of "Wood", and is one of the legendary "Ten Legendary Warriors" that saved the ancient Digital World. It is the largest of the Ancient Digimon, and its body is loaded with various mechanisms that allow it to display tricky attacks and movements. Its abilities were later passed on to the "Plant Digimon".
