Dr. Strange & Dr. Doom: Triumph & Torment

In 2013, Marvel brought together two of its most formidable mystics—Doctor Strange and Doctor Doom—for a single, self-contained graphic novel. Written by Roger Stern with art by Kevin Nowlan, Triumph & Torment pits the Sorcerer Supreme against the monarch of Latveria in a battle of wills and wizardry, united by a shared quest into the depths of Hell itself. This one-shot stands as a definitive, character-driven clash between ego and altruism, a must-read for fans of Marvel's darker, more philosophical corners.
