The Incredible Hulk #181

Canadian super-agent Wolverine teams up with the Hulk to battle Wendigo. Once the monster is felled, however, Wolverine turns on the Hulk and the two battle. Marie goes ahead with her plans of trying to transfer the power of the Wendigo into the Hulk but when the guilt becomes too much for best friend Georges who feels responsible for Paul's monstrous condition, he works the change on himself. Paul Cartier is returned to human form and Georges becomes the Wendigo.
