- Synopsis
- Two rival fan clubs are debating who is stronger, Thor or the Hulk? Thor happens to be passing by and drops in to offer his opinion. He relates the story of their epic battle (in Avengers #3) and describes a previously unseen scene in which he and the Hulk tussle. He goes into deep thought and when pressed, cannot say who is the stronger because he has insufficient proof! Days later, the Hulk gives thought to his meeting with Thor and vows that, next time, Thor will be smashed forever!
