Essential X-Men #6

In "Legacy (Part Six)," Professor X fights a desperate psychic battle against Mr. Sinister, who seeks to seize his mind and body, while Dr. Amanda Mueller attempts to eliminate both to harness Sinister’s power for her own youth. As the X-Men and allies like Gambit, Cyclops, and Bishop struggle through traps and betrayals, the line between ally and enemy blurs—especially when the Brood Queen and the enigmatic Miss Sinister enter the fray. In the aftermath, Sebastian Shaw retreats to a quiet moment with a young woman whose unsettling beauty and crimson mark hint at a darker legacy—she names herself Miss Sinister, and the game shifts.

In "Walkthrough (Part One of Two)," Professor X summons Cyclops to a secluded meeting, sparking tension as Scott resists the psychic intrusion following his unsettling experience in Mr. Sinister’s mind. Meanwhile, Rogue retreats to a forgotten Australian Outback town, seeking peace amid memories of the X-Men’s past, while Sebastian Shaw pushes the Hellfire Club toward a revival of its old ambitions.
