Barian Battlemorph

Bariarphose (バリアルフォーゼ Bariarufōze, a play on "Barian' and "metamorphose"), known as Variarphose in the Japanese version is the transformation Barians undergo in order to regain their original body and appearance after having acquired a human-like form. Normally, Barians cannot retain their original body structure in a low-energy world such as Earth, so they must take on a human form when in such place. They can only go through this process when in an environment that emulates a high-energy world, namely, a Sphere Field. The field is usually generated by using a Barian's Sphere Cube. By metamorphosing into their true bodies, Barians gain the advantage of being able to use Over-Hundred Numbers and their "Number C" evolutions, albeit with a risk to their own lives.
