Sepsis

Dr. Van Metek was once a brilliant virologist and cell biologist who dedicated his life to curing genetic diseases. He worked on ways to rewrite human cells, to “heal” from the inside. But his obsession went too far.

In secret, Emil designed **a living viral strain fused with his own DNA** — a parasite that could repair cells by replacing them with copies of itself. His goal: *to end disease forever.* But the strain didn’t heal — it consumed.

One night, during human trials that were banned by every ethical board, Emil injected himself. His body spasmed, his veins lit up with sickly green light, and his cells began dying and being replaced by parasitic ones. His skin tore in places, oozing toxic filaments. He screamed for help, but by the time his assistants reached him, he had already infected them by accident.

They collapsed in seconds, their bodies eaten from the inside out. Emil survived — because he had become something worse than human. He was now the host of billions of self-replicating viral cells. His blood was poison, his breath carried infection, and with a single touch, he could rot another person’s body away.

He took a new name, one whispered in terror: **Sepsis.**

He no longer saw humanity as something to save — but something to *purge.* In his twisted mind, he was no longer Emil Karros, failed scientist. He was the world’s immune system. He believes the Earth is sick, and he is the cure.

Now, Sepsis travels like a walking epidemic — infecting, consuming, and spreading. He doesn’t seek money or power. He seeks extinction. And when he sets his sights on **Earth’s newest heroes, TackForce,** he vows to consume them from the inside out — until he discovers Blu Tack’s cells cannot be infected. That drives him insane — because it means there is life he cannot dominate.
