Marvel’s Flashback Month drops the X‑Men into a pre‑X‑Men era, and this issue rewinds all the way to the earliest days of Charles Xavier and Erik Lehnsherr—long before they became Professor X and Magneto.
The story follows a young, still‑idealistic Xavier as he travels the world studying mutant genetics. Along the way he crosses paths with Erik, whose worldview is already shaped by trauma, suspicion, and a fierce instinct for survival. Their meeting is tense but electric: two brilliant mutants recognizing something powerful—and dangerous—in each other.
