666 (Trihexa)

Powers & Abilities
Immense Strength: 666's powers were initially largely unknown due to being sealed for many years. 666 has power on par with God of the Bible, Odin, Zeus, Fractell Flame, Hades and Mavis in its prime; a clash between Trihexa and Fractell Flame is feared because of the potential damage it could inflict to the world due to their strength, with Azazel believing that a clash between them, will result in the end of the world[1]. In fact, it is such a true monster that it could easily destroy the entire world on its own. Ragnarok stated that it took thousands of forbidden level seals for the God of the Bible to seal it away. Upon gazing it for the first time, Azazel notes that just its aura alone is enough to make a normal person go crazy. According to Allen, only Mavis at full power and Fractell Fame can destroy it as 666's absolute overwhelming power made it impossible for Jesus, who is an immensely powerful God, to destroy it. In a matter of days after being unsealed, it managed to cause massive damage to multiple mythological factions, nearly completely wiping out Heaven, Grigori, Yggdrasil, Valhalla and Asgard.

Fire Breath: 666 can fire a powerful fireball from one of its heads.

High Speed Regeneration: Aside from its nigh indestructible skin, Trihexa possesses high speed regeneration and is able to heal itself in an instant if any parts of its body were damaged, being able to regenerate even if turned to ashes. Due to its immense regeneration, Trihexa can easily survive immensely powerful attacks to the point the Scale Mails of extremely powerful Longinus Possessors such as Kemo Kemo, Grim, Mephisto, Uma, Vali, Grandhelm and Levy could not inflict any permanent damage on Trihexa's body. According to Dio, even with the combined force of the numerous Gods, Devils, Dragons and Underworld Beings of various mythological factions, Azazel, Michael, Raphael, and three of the current Satans including Dio, a Super Devil himself, it will take an enormous amount of time to be able to defeat or even seal Trihexa due to its tremendous regeneration powers.

Body-Splitting: Trihexa can split each of its heads into seven different bodies.

Flight: Trihexa is shown capable of flying without wings. Although the core of Trihexa is able to sprout six wings (bird, dragon, bat, and various other beasts).

Mass Ancient Relic Production: With the help of the Anti-Myth Faction's modifications with the Twilight Grail, Trihexa can mass produce Ancient Relics (Annihilation Pump, Dividing Wings, Booster, Zenith's St. Longinus, Vritra's Relics, Tempest Gunner etc) and Dragons Festival armors. It was gone after Valcure, Chiho and Arthur got back Elaine's Grail.

Core Expulsion: 666 has shown the ability to release its core. It demonstrated this when one of its cores appeared before Uma due to Trihexa's curiosity when it sensed both Fractell Flame's and Mavis' powers coming from him.
