AXZ Episode 3
The person who exists at the top of the hierarchy of the organization that the Alchemists belong to, the Lodgemaster of the Bavarian Illuminati. He himself is a super high-class alchemist and can utilize all of the alchemy that his subordinates use, but even better.
AXZ Episode 11
His true identity is a scrapped human prototype, a puppet, created even before the era of prehistoric civilization. The reason he was scrapped was for being too "perfect." He was outfitted with all the abilities and functions that his creators wanted, but only those and nothing else. Eventually it was determined that this caused him to have zero potential for evolution and thus he was passed over as being officially designated as "human." He was scheduled to be expunged, but broke free of his chains and fled. His creators ceased to hold any further interest, leaving him to lurk throughout history. Instead, his creators combined the qualities they both liked and disliked into an imperfect being (the human species), which they formally accepted. However, Adam realized he had surpassed these beings and thus was determined to find a way to stand on equal ground with his creators. That was the beginning of the society formed by Alchemists. In order to stand above all else, the Bavarian Illuminati was created under the ideal of seeking perfection. However Adam was already "perfect," yet could not produce any new power or plans on his own. Thus in order to reach his creators, he compensated by leaving it all in the hands of the other Alchemists. The lapis philosophorum, the transmutation of gold, Tiki, his use of the four elements (Aristotle), and even his cool hat were all things laid out before him by someone else's research. The perfect yet incompetent Adam has always progressed toward his goal with a smile on his face, treading paths that had already been forged by others.
AXZ Episode 13
Having exhausted a considerable amount of his power to open an alternative God's Gate within the Orion constellation, he planned on the Divine Weapon being able to make up the difference during the final showdown with the Adaptors. However, he was promptly defeated in a single blow from the God Slayer. Facing this desperate situation, he was left with no choice but to divert the energy he uses to maintain his beauty (quite an enormous amount), and turn it into offensive power. Thus, he grew horns and took on a final form, which resembled that of a demonic goat. In reality, this is his true form that he has kept hidden behind his pride out of shame. On a related note, in the 19th century there was a sole member of the Bavarian Illuminati who caught a glimpse of Adam's true form and used it as the basis for a painting, in which he also inscribed the words that embody Alchemy (Solve et Coagula).
The true nature of this puppet who sought the Divine Power to raise himself to the level of his creators was in fact deeply ugly and demonic.
XV Episode 1
The Lodgemaster of the Bavarian Illuminati, who sits atop the organization.
His true form was that of a puppet, created before even prehistoric civilization. He was cast aside, a discarded prototype for mankind.
The reason for his abandonment was being "too perfect."
Although he possessed every ability and function his creators, the Annunaki, wished, it was reasoned that he had no potential beyond that and was dismissed from being officially designated as "human."
Aiming once again to become the ruler of the planet and foreseeing the imminent revival of the Annunaki, he sought the "power" that would allow him to stand on their level and mount his resistance. In this, he found himself at odds with the Symphogear Adaptors and the rest of the Illuminati's leadership.
With his dying breath, he spat a curse upon tomorrow and sneered at the God Slayer's fist.
