Hi hollingp67 - I think this was left out because we considered it to not truly be a comic book, since it was basically text articles, wasn't it? We are open to discussion here, if you users think it should be included. Just checked Overstreet and it's not listed there either.
As I remember it started off as a series of articles with reprints of the original art from the initial appearances of the characters, but I think they did start introducing some of the newer characters as the series went on. There was an issue dedicated to Mantillo which has Rocket Raccoon on the cover and Damage Control first appeared in one of the Annuals and that is creating a little bit of heat on some of the issues there.
