Karudio

Japanese name:

カルディオ

Another horse mamodo like Ponygon, Karudio was first introduced as a rival for the fire horse. At some point in the past, the team was ambushed by two allied Mamodo named Snail and Maraion, taking turns to attack Karudio, which they felt was not right. Although Karudio and Sauzaa defeated the two mamodo, the battle left them with a negative prejudice regarding "teamwork" and they are highly hesitant to work with others.
