Vexarr

Vexarr is a Daikaiju, a giant monster. He is an aquatic beast who can control the oceans, causing tsunamis and earthquakes. He is not only the strongest, but the last of his species.

Origin
Once there was a powerful demon god who created a powerful race of monsters to do his will. He used them to attack an ancient civilization on Earth. The powerful mages of this civilization could not even stop them so instead, they sealed the Daikaiju inside a dimension for eternity. Many people were killed that day and it was all they could do to stop the Daikaiju. They escaped a hundred years later but an unknown powerful Saiyan destroyed them but one survived and killed him. His dying will was to seal the monster away and so his son, carrying out his will sealed the monster for eternity. That monster was Vexarr.
