Marvel's Mightiest Heroes #122

In this gripping tale from Marvel's Mightiest Heroes #122, a failed experiment transforms Otto Octavius into a man haunted by his own creations, as his robotic arms gain a will of their own. When the scientist turns his machines toward seizing control of an atomic facility, Spider-Man must step in to stop him—before the city is caught in the crossfire.

Otto, barely clinging to sanity after a near-fatal accident, stumbles into a descent he never saw coming—guided not by hope, but by four of the most lethal weapons ever forged. In the quiet aftermath of ruin, he finds himself drawn into something far darker than he ever imagined.

In "null," a desperate Doctor Octopus, wracked by lethal radiation, races to uncover the final truth about Spider-Man—pushing his mind to the brink in a bid to redefine their long-standing rivalry. With time and sanity slipping away, the stakes aren't just life or death, but the very nature of their enemy.
