Create a futuristic demonic boss character named RAAV-AI. He is an AI version of the mythological demon Raavan. The model should have one main robotic skull face and 9 floating cybernetic heads rotating in a ring behind him. His body is armored with molten bronze and black obsidian metal covered in glowing Sanskrit-like symbols. He has 4 arms — 2 with retractable blades and 2 operating floating holographic screens. His legs are reversed like a demon goat’s, ending in metal claws. He carries a staff that emits electric nightmares. His back has fiber optic wires like dreadlocks. Visual style should be semi-realistic with glowing VFX, glitch effects, and a haunting aura.
