Ogretail

Ogretails are small Aragami that boast the largest population out of all of them. Eric der Vogelweid was devoured by one because he let his guard down.

God Eater Burst
''A smaller Aragami with a giant tail sporting an ogre-like face. Mainly devours corpses of other Aragami. Increasing in number in various regions. First appeared on the American Continent: now boasts the largest population of all Aragami. Not particularly difficult to take out when attacking from the side. Still, as its tail-spinning attack is powerful, be wary of it when it braces both legs.''
