Xero

Before he became Xero, Dr. Marcus Chen was a man who had once loved a woman so completely that when she disappeared from his life, he turned to mathematics to fill the space she left. Her name was Debian. She had green eyes and a mind that moved like water around obstacles. He had not spoken her name aloud in eleven years. He told himself he had forgotten her. He had not forgotten her.

In a forgotten sub-basement deep beneath Neo-Shanghai's corporate spires, Chen worked on the equation that would end the world — though he did not know this yet. He only knew that he was close. The air around him crackled with mathematical potential. The quantum processors hummed their warning song. He knew he should stop. He knew some equations were never meant to be solved. He pressed forward anyway.

In that moment of divine calculation, as his trembling finger executed the final command, Marcus Chen ceased to be merely human. The division by zero — that mathematical impossibility — tore through the fabric of existence itself. His flesh became probability. His bones transformed to pure mathematical theory. The first Xeroman was born in a flash of impossible light, his consciousness exploding across infinite parallel realities.

He had become something new — something impossible — a living paradox that exists in the spaces between equations. The security systems, designed to protect against conventional threats, sparked and died as his presence overwhelmed their binary limitations. Through failing cameras, security personnel watched in horror as their monitors displayed a being that existed in multiple states simultaneously: a walking violation of everything they understood about reality.

He had wanted immortality. He found something closer to omniscience. And in the space between those two things, he discovered what Marcus Chen had never allowed himself to feel — grief. Infinite, branching, uncontainable grief. In every parallel reality, in every version of this moment, in not a single one had she stayed. His transformation was not a triumph. It was the universe's most precise answer to a man who sought to escape his own heart by dividing it by zero.
