Havok

Few Marvel characters carry as much Silver Age weight as Havok, who burst onto the scene in The X-Men #54 in 1969, courtesy of Arnold Drake and Werner Roth. A proud member of the X-Men, he's spent nearly six decades — and 561 catalogued appearances — woven into the very fabric of Marvel's mutant mythology, headlining The Uncanny X-Men, X-Men, and X-Factor across a run that stretches all the way to 2026. With 29 key issues to his name, he's the kind of character whose appearances make collectors sit up straight, and the roster of characters he shares the page with — Wolverine, Cyclops, and Ororo Munroe among them — tells you everything about the elite tier of Marvel storytelling he inhabits. If you're tracing the spine of X-Men history, Havok is a name you'll encounter again and again, and for very good reason.
