Beware My Power! Emerald Reckoning! (MCU X Male "Green Lantern" Reader)

Alex Kane was a soldier-a warrior trained to fight in the shadows, to complete the impossible, and to bring his team home. But war changes people, and not everyone makes it back. Haunted by past failures and struggling to rebuild his life, Alex thinks his days of battle are over.

Until the ring finds him.

Chosen by a dying Green Lantern, Alex is thrust into a war that spans the stars, wielding a power fueled by will alone. But he is not the only one who understands fear. As an unseen enemy stalks Earth, preying on its darkest emotions, Alex must decide-will he rise as a protector, or let his past consume him?

With SHIELD watching his every move, a rogue Lantern hunting him down, and whispers of a coming war from beyond the cosmos, Alex stands at the edge of something far greater than himself. Because in the shadows of Earth's greatest heroes, something stirs... and the battle for the universe is just beginning.

Willpower alone won't be enough.
