One of the most important X-Men villain keys of the Copper Age. Uncanny X-Men #221 features the first full appearance of Mister Sinister, the mastermind geneticist whose influence would shape decades of mutant history.
From the Marauders and the Mutant Massacre fallout to modern Krakoa-era storylines, Sinister has evolved into one of Marvel's most complex and enduring villains. This copy is graded CGC 9.6, offering outstanding presentation and strong collector appeal.
Mister Sinister has become far more than a one-off villain. Over the years he's grown into a central figure within the X-Men mythos, making this issue one of the most consistently sought-after first appearances from the late 1980s.
Whether you're building a Claremont-era run, collecting major X-Men keys, or looking for a strong investment-grade mutant book, this one deserves attention.
