Boom!!
Uatu threw a heavy punch. The Higher-Dimensional Substrate beneath his feet remained intact.
His second punch came down hard, shattering the ground that held him into a storm of dimensional fragments.
Ultron did not retreat a step. He took the blow, backed by the force of an entire universe, head-on.
Hairline cracks spread across his Vibranium chest armor like a spiderweb. But six streams of energy from the Six Infinity Stones surged out, repairing every bit of damage in a fraction of a second. The cracks vanished as though the blow had never landed.
He held his position, scarlet electronic eyes flaring, and thrust a palm straight forward.
What surged from his palm was neither wind nor a high-energy beam. Through the Six Infinity Stones, it was a mass of spacetime folded and compressed to the extreme.
As it advanced, layers of dimensional space along its path crumpled like wastepaper, folding over themselves and breaking apart.
Uatu slipped aside from the direct hit, but the edge of the fold grazed his shoulder. A small patch of flesh and the dimensional substrate beneath it simply vanished, leaving a smooth, curved hollow.
There was no wound, no energy burn, no scrap of flesh. It was as if someone had erased a patch of his skin.
Uatu glanced at his missing flesh, then looked up. He never slowed. The loss was too small to distract him, and his attention locked back onto the machine.
The coordinates of their battle shifted wildly.
In the first second, Uatu stood his ground and punched. Ultron raised an arm to block from hundreds of meters away, squeezing visible ripples out of the space between them.
In the second, both figures teleported elsewhere. Fist met palm with a thunderous crash, and a ring of dark-gold primordial light
