In physical form, Waroga can teleport at short distance and shooting energy shots from its arms. It's certain that Waroga posses some advance technology, capable of take control of creature by implanting bio-chip.

To carries out its plan, Waroga use a bio-chip to control a peaceful monster Galbas and send it against humanity. The similar bio-chip also embedded on earthling woman Reni Kurosaki, whose Waroga saved from satellite accident.
