I wish you had talked to me before going through the effort of adding a new category to all those pages. I could have helped refine the idea.

From what I can find, the Marvel Action Universe was a programming block for shows from the 70s and 80s. I think the Action Universe you're thinking of is the Marvel Action Hour that in its second season was renamed Action Universe for some markets. We don't really need to categorize which characters appeared in promotional material since that kind of thing isn't really part of the show or consistent between markets.

The best place for this would be to describe it on the Marvel Action Hour page. As for Captain Marvel, the best place for that would be on his disambiguation page noting that he only appeared on promotional material.
