The collision is seismic — two Viltrumite bloodlines, one pure and ancient, one hybrid and rage-forged, slamming into each other above a ruined skyline. Thragg opens with the calculated brutality of ten thousand years of warfare, his strikes carrying the muscle memory of a Grand Regent who has never lost a one-on-one war. He works Mark's ribs, targets his windpipe, drives an elbow into the orbital socket with the cold precision of a creature who understands Viltrumite anatomy better than any living being. Mark crumples, bleeds, and spits a tooth — and then gets back up. He always gets back up. Thragg's eyes narrow. He has killed gods. This should already be over.
Mark pushes back with everything he has — his father's training, his own accumulated punishment, the absolute refusal to stay down that has defined every fight of his adult life. He catches Thragg with a full-speed haymaker that cracks the Grand Regent's jaw, follows with a knee to the sternum that sends him spiraling through a skyscraper in a cascade of glass and steel. For a moment, it looks like momentum. Then Thragg straightens his jaw with one hand, rolls his neck, and smiles — that terrifying, patient smile of a being who has endured far worse and simply kept going. Mark knows then, with terrible clarity, that he has not hurt him enough.
The exchange degrades into something primal and inexhaustible. Thragg cannot reach deep enough into Mark's Viltrumite healing to end him permanently — every catastrophic blow that would kill a human regenerates in seconds, and Mark's hybrid physiology proves as stubborn as it is maddening. He cannot be held either; every grip Thragg secures, Mark tears free from with the frantic, animal desperation of someone who has survived the unsurvivable before. Meanwhile Mark cannot accumulate enough damage on Thragg to cross the threshold — the Grand Regent's body absorbs punishment the way a mountain absorbs weather, and his own regeneration quietly erases every wound before it can stack into something permanent.
Hours bleed into each other. The landscape around them is unrecognisable — craters where streets were, fires where buildings stood. Both men are covered in their own blood and each other's. Thragg moves with slightly diminished speed now; Mark's left arm hangs at a wrong angle. But neither falls. Neither can be put down and kept there. The Grand Regent eventually halts, hovering, studying Mark across the wreckage with something approaching respect — a word he has never had use for before. Mark hovers opposite him, chest heaving, eyes never dropping. Two immovable things have met, and the universe simply does not have a mechanism to resolve it.
WINNER: Stalemate
