One of the things I found most surprising about the first issue of the Avengers when I read it as part of the “Son of Origins” collection was the role of the Hulk. In the preview, Stan Lee speaks of using Loki as a villain that could face a group of heroes. But, in the story itself, Thor takes on Loki by himself while the rest of the team (Iron Man, Ant-Man, and the Wasp) fight…the Hulk! Due to Loki’s trickery, everyone was, in fact, summoned to face the Hulk. In the end, everyone is friends and the big green guy joins the group. But just to show how little Bruce Banner’s alter ego fit in the team concept, he left at the end of issue two. In issue four, he was replaced by Captain America, who tried to convince the Jade Giant to rejoin later in the teens or thereabouts. Therefore, despite being a founding member, the hulk has never hung around with the Avengers for long.
Which is why I drew this picture. I think it shows the relationship between heroes such as Iron Man and the purple-pants wearing behemoth. You can’t be sure if Hulk will help you or smash you. I guess you take the chance, because you definitely don’t want him fighting for the other side.
