Moginaian were small to medium size aliens who dwelt in Planet Mogina in Universe 7. They were cave dwellers like in behavior and were not able of using ki, thus using stone made hammers to hunt their food.
The Moginaians were destroyed by the God of Destruction, Beerus, after their Chief Moginaian refused to hand Whis the Dinosaur meat they've hunted. As a result of this, they became extinct in Age 778.
Moginaians can change their appearance into a much larger and stronger dinosaur-like form by transforming into "Battle Mode".
