Hello! I'm new here and I have some questions about adding character appearances to issues. I apologize if this has been asked before, I tried searching for old posts but couldn't find any of the answers, so here goes:
*Should a character be added to an issue even if they only appear on the cover (like Spider-Man and the Fantastic Four on the cover of Daredevil #1)? If so, do variant covers count too?
*Does an appearance count even if the character is only impersonated by another? Also, if that is the case, how "convincing" does it have to be (i.e. a character wearing a halloween costume of a superhero or a shapeshifter mimicking another character perfectly)? Do retcons (like how The Patriot was retconned to have been the post-WWII Golden Age Captain America) count as well?
*What constitutes as an appearance? Does the character appearing in a picture or as a statue count? In a flashback or in a dream? Or a character being "heard" (for example, a speech bubble from off-panel or through a radio) but not actually seen?
Thanks in advance!
