Orcus
His smirk was swallowed by a gasp when she wrenched him against the impassable border of their arena. Reeling automatically, the initial shock diverted with the length of Orcus's arms, their scenery groaned at the test between its skeleton and his divinely forged back. Abandoning all distractions to the purpose of her weaponized flesh, Mira's expression flared red with the pure haze of aggression, the picture of a moment that he carved a perfect replica of into a place deep in the vaults of memory. Another blade gouged her shoulder and his grip snapped at the hold, instantly breaking her wrist, but her will asserted itself. It heard pain and said no, it tasted vulgar offense against anatomical limits and ignored it, and all he could do was brace as it lay directly into him. Booms that could nearly send cars flying rattled the bars to their foundation, sparing the audience only for the unfairness of their protections.
Past the jackhammer pummeling his gut, burying itself on his stomach, it was difficult to squeeze out words. His voice came out in hacks, caving in with his abdominal muscles, then caked in red as the unstoppable train of slams began to pulp the organs beneath, letting out only a ghastly whisper of satisfaction. "That's it."
The swords of chaos had vanished, and now the armament formed a vortex above her head, where a swirling point emerged, accelerating. It accrued heat and power, casting sparks of darkness into the emptiness around it, the hollow eye of the storm that birthed itself in the shaky confines of the metal fencing. It stood to tell her only one thing, in perfect honesty - be superior, or die. The same thought rippled through Orcus's freed arm, bending in the little space it could afford, sweatdrops that clung to that heat not flicking off but evaporating wholesale.
Then it smashed onto her jaw, and a veritable mountain hurled from the hand of heaven displaced her face, with speed and power that outperformed all of Orcus's displays until then.
