There's been a shakeup at Marvel. Not in the sense of a major restructuring, but a change that sees a new creator receiving a credit for helping create one of the publisher's most popular characters. In a controversy that's quickly become the talk of Comics Twitter, Roy Thomas is now being credited as one of the four creators of Wolverine. Thomas, a longtime Marvel Comics writer, editor, and creative, served as Editor-in-Chief of the House of Ideas during the period in which Logan first appeared.
