Trapped in an endless void after falling from the broken Bifrost, Loki is saved by a harmless cosmic spirit. When the Other finds them, the spirit is dragged along with the Asgardian into Thanos' schemes for Earth. Fueled by fear and desperation, Loki plans to escape his bonds using the spirit, trapping it in human form. To his regret, Loki does not anticipate his creation having a will of its own. And too late does Loki realize it's not as harmless as he once thought.
