Potamus

Potamuses are enemies in Xenoblade Chronicles X under the Theroid classification. They have been domesticated by the Nopon and can commonly be see around the Nopon Caravans of Mira.

Description
''These herbivorous, bank-dwelling creatures live in herds of one male and multiple females, and spend the better part of their days in the water. Males are known for their terrotorial tendencies, driving off invaders with great animosity, though females may also display similar traits when other creatures approach their young.''

''Equipped with mighty fangs and horns to match their temperaments, potamuses are actually more dangerous than many fiercer-looking carnivores. The Nopon, however, have succeeded in domesticating them to haul freight.''
