When Barry Windsor-Smith revealed how Wolverine ended up getting unbreakable adamantium all over his bones, it was pure comics gold. And it all took place in the unlikeliest of Marvel titles at the time. Despite being Comics Code Approved, BWS gave us page after page of violence, gore, psychological torment and butt-naked Logan which was pretty shocking for newsstand fare in the early '90s. And there are moments when it's still shocking, now! It's more like a relentless horror than an X-Men book. Windsor-Smith doesn't answer every question, though, leaving more mysteries to solve. These were picked up by Larry Hama and Marc Silvestri in Wolverine's regular solo series (during MUTANT GENESIS ).
