Marvel: Kryptonian Bloodline, Dropping In to Save Tony with My Bare Hands

Leon transmigrates into Marvel and is adopted by Howard Stark, becoming Tony's younger brother. On the night of his eighteenth birthday, his Kryptonian heritage officially awakens. Sunlight lets him evolve without limit, granting him the full Superman package: a body of steel, heat vision, freezing breath, super-hearing, and more. Tony gets three ribs snapped by Leon's freakish strength and ends up in the ICU.

Six months later, Leon has soaked up stellar radiation in low Earth orbit. He punches through a space capsule and returns to Earth, landing precisely in a cave in Afghanistan. Tony is clutching the shrapnel lodged near his Arc Reactor, writhing in pain. In the next instant, Leon's hands move like a blur as he pulls more than a dozen metal fragments out of Tony's chest with his bare hands, then uses heat vision to stop the bleeding and seal the wounds. Tony looks down at the dozen or so extra holes in his shirt and stares. "You call that sunbathing?"

Gunfire erupts outside, bullets pouring down like rain. Leon steps in front of them, and every bullet clangs against his skin and bounces away. He turns and grins. "Big bro, you can retire that tin suit."

"Obadiah, Hydra, Thanos: they can line up and come at us one by one."
