Harihara represents the unity of the Hindu gods Vishnu (Hari) and Shiva (Hara). Also known as the Shankara-Nayarana, Harihara's right half represents Shiva and the attributes it is associated with: destructive, terrifying, and feminine, while the left half represent Vishnu as the pacifist, auspicious, and masculine. Because worshipers believe each deity is the Supreme Being, the unity of the two represents the sacred ultimate power of the universe, supreme over all other gods. The exact nature of this unity is still debated among the Hindu philosophical schools.
Themes: Hari-hara and Hari-Hara the Second Movement
Harihara is the Atma Avatar of Angel, the mysterious person that appeared at the top of the Karma Temple. When Serph and the rest of the Embryon confronted her in their attempt to rescue Sera, Angel assumed this demonic form. It could be said that Harihara represents the true nature of Angel.
There are three forms that Harihara took in the battle. The first one is a representation of Vishnu; a white-faced figure, while the second form is characteristic of Shiva; the fierce black-faced figure. These forms are switched over at certain intervals. The final form, a gargantuan being, is fought together with six elemental Cores; Earth Core, Fire Core, Wind Core, Water Core, Elec Core and Gold Core.
