Sins of Sinister

In 2023, Marvel’s Sins of Sinister kicked off a single-issue event that twists the X-Men’s Krakoa era through the lens of Mister Sinister’s machinations. Written by Kieron Gillen with art from Carlos Gómez, David Baldeón, and David López, the story expands beyond the mutant nation to ensnare Spider-Man in its dark alternate timeline. This dense, one-shot saga matters for recontextualizing the quiet dread of Sinister’s long game, offering a chilling “what if” that reshapes the Marvel Universe’s future.
