John Byrne stated, in both interviews and his website, that he drew a possible face for Wolverine, but then learned that Dave Cockrum had already drawn him unmasked in X-Men #98 (April 1976), long before Byrne’s run on the series. Later, Byrne used the drawing for the face of Sabretooth, an enemy of the martial artist superhero Iron Fist, whose stories Chris Claremont was writing. Byrne then conceived of the idea of Sabretooth being Wolverine’s father. Together, Byrne and Claremont came up with Wolverine being approximately 60 years old and having served in World War II after escaping from Sabretooth, who was approximately 120 years old. The plan had been for Wolverine to have been almost crushed in an accident; he would discover, when attempting to stand for the first time after recovering, that his healing factor does not work on bones, and his legs immediately break. He then spends over a decade in a hospital bed, almost going mad, when the Canadian government approaches him with the idea of replacing his skeleton one bone at a time with adamantium, the claws being a surprise. This origin, too, was never used.
