Kaiju Soul

Kaiju Soul (怪獣の魂 (カイジュウソウル), Kaijū Sōru) is a Take Over utilized by the S-Class Mage of Hydra Head known as Mathilda Barbatron. Although formidable, Mathilda seldom uses it due to the fact that she has a tendency to lose control of her temper, like many Take Over users have a habit of doing. And despite granting the caster a significant power boost, it is at its most powerful around full moon. As such, one can deduce that it runs on some sort of lunar energy and is therefore more potent when the moon is visible. However, it can still be used in full daylight to a similar effect.

Trivia

 * The appearance of Kaiju Soul is derived from Keine Kamishirasawa's were-hakutaku form in Tōhō.
