In the prologue Wolverine wakes up dazed and confused in a crater in the mountains. As he tries to recall how he got there he is confronted by the Hulk, jogging his memory. Wolverine was sent by Department H to track down a beast called "the Hulk" by the US Military, which has been rampaging across the Canadian Wilderness. In the ruins of Elkford, British Columbia Wolverine picks up its scent. After a few hours tracking the creature in the wilderness, Wolverine finds Dr. Bruce Banner. He questions him but starts to violently interrogate him after realizing that he had the same scent as the creature. Ignoring numerous warnings, Wolverine continues the interrogation until Banner transforms into the Hulk and sends him flying, and crashing into a crater.
