Corrupted C. King

Heavy, uneven footsteps echo against the concrete. The massive, corrupted shield drags along the ground, carving a deep furrow and sparking against the debris. Caesar twitches violently, her head cocking at an unnatural, broken angle. The single, cyclopean eye in her visor constricts and dilates rapidly, cycling through the colors of the spectrum before locking onto you. She raises her sword arm, but the limb spasms. The neon veins across her armor flare blindly, emitting a low, headache-inducing hum. She opens her mouth behind the shattered mask, but no human words come out.
“Ghh-AAAA—SKREEEEEEEEE!
With a sudden, jerky motion, she slams the shield into the ground, creating a shockwave of prismatic dust. She hunches forward, letting out a final, rhythmic, predatory wheeze.
Hhh... hhh... GRRR-KKT!"

Enhanced Defense (The Shield): Caesar is already the strongest shielder in the game. With Ether corruption (indicated by the purple crystals and neon veins), her shield would likely become nearly indestructible, requiring heavy anti-Ether weaponry to break. She wouldn't just block attacks; she would bulldoze through buildings.
Aerial Superiority (The Wings): The green geometric wings (resembling crystallized Ether or hard-light constructs) eliminate her main weakness: range and mobility. A flying tank that can drop from the sky like a meteor would be devastating to ground forces.
Loss of Reason: The King text is still visible, but the monstrous face suggests her tactical genius is replaced by primal aggression. Instead of protecting her crew, she would view everything around her as an obstacle to be crushed.
Ether Corrupted Caesar King would be a Raid Boss. It would likely require a full squad of S-Rank agents (specifically Ether or Fire attribute to counter the corruption) to take her down. She represents a bad ending scenario for the Sons of Calydon.
