Notes: Text pages consisting of "interviews" with the characters involved in the origins of the Avengers. As such, characters listed here don't "appear" per se, but their presence in the text as interviewees is enough to count as an appearance.
This chapter seems to forget its numbering, and skips from chapter 9 to chapter 12. There are no missing chapters in between. The next chapter seems to resume the correct numbering at number 11. Because of this, technically "Chapter 12" comes before "Chapter 11"
