Helios Alpha

His real identity is the Sphere Raiser itself, after Valzelide merged with Kagutsuchi and was defeated by Zephyr in the previous Holy War. Later, he shared his existence with Ashley as the result of gruesome human experiments and as the other wing of Hyperion. However, in the end, he gains his true self from Sphere Raiser and evolves into Sphere Saver to respond to Ashley's wrath.
