This is a compilation of move lists of Orochi.

Orochi is playable through cheats only.

===============
Command Attacks
===============
*Monkyakujin/Arahabaki (Gate Visitor/Dweller on the Threshold) - near opponent, ← or → + C or D
Orochi levitates its opponent into the air, then manifests a slash on them that knocks them away. The D version has Orochi switch sides with its opponent while levitating them.

===============
Special Attacks
===============
*Kaijo/Harae (Cancellation/Exorcism) - ↓↘→ + A 
Orochi casts a mote of bluish-white light forward that creates a void rift as it travels. It is not strictly a projectile, as indicated by the fact that it does not disappear on hitting a foe.

*Utsushi Iwai (Exposed Worship/Projecting Celebration) - ↓↘→ + B or C

Orochi juts a hand forward (B) or upwards (C). If its opponent hits with a physical attack where Orochi is gesturing, it counterattacks by generating a shield of energy that shatters and damages them. B defends against mid attacks, while C defends against specials, DMs, and aerial and high attacks.

*Tadasu (Ascertain) - ↓↘→ + D

Orochi creates a momentary rift in front of itself. If hit by a projectile, the rift will swallow it and disgorge a bolt of violet fire in retaliation. The Tadasu bolt does little damage on its own, but will juggle a hit opponent.

*Karankou/Ho no Susori (Fire Orchid Descent/Rinse of Fire) - →↘↓↙← + Any button

Remote attack, Orochi summons a pillar of bluish-white energy to strike down from the sky. The button used determines how far away the pillar appears.

=================
Desperation Moves
=================
*Kon/Marukare (Blend/Rounding Reaper) - ↓↙← + Punch

Orochi raises its hands upward and calls forth a storm of deathly white energy from the skies to attack the entire screen.

*Ookami/Oomiwa (Great God/Great Survey) - →↓↘ + Punch

Orochi glows with pale blue energy while making the entire area flicker with white energy. During this time, the opponent will be pulled towards Orochi until Oomiwa wears off. If the enemy gets too close, Orochi will stab them with its hand and pull out a piece of their life force, in the form of a bluish white orb. It will then crush the orb, inflicting severe damage as the victim is blasted away.
