Embryo resents the world from a position which is one step higher than that of the administrators like the Misurugi family. He owns the lost weapons and techniques of ancient times. He has piloted the Black Ragna-mail "Hysterica" which has six wings and has a form similar to Ange's Villkiss. He once annihilated Jill's squad before the latter's rebellion, thus making him her arch-nemesis. He's the creator of the Mana system and is able to heal fatal injuries with Mana. He also knows the same song as Sala and Ange which he uses to control Hysterica, the more powerful prototype of current Para-mails. He created the World of Mana by taking the Mother of DRAGONs, Aura and used her life force as energy, while making the Norma and DRAGONs fight each other in order to harvest the Dragnium crystals that are inside the bodies of the DRAGONs in order to re-supply Aura.
After the assault of Arzenal, he was able to make Salia, Ersha and Chris swear loyalty to him.
