Well this is what I wanna talk about Characters who are mentioned only,made cameos and Behind the scenes people say they don't count as actual characters,to me that is stupid, but what about Eddie Brock he appeared in Web of Spiderman #118
and he had his had in the way that counts as an appearance,even though it was behind the scenes.also just because they don't actually appear doesn't mean that counts as an appearance so they should make an appearance wherever the other person likes it or not.
So let's start the ratchet & clank franchise has some characters mentioned an appeared in behind the scenes before they make their actual full appearance.They are seen in pictures as cameo which counts as an appearance and Resident evil has a lot of mentioned characters and pictures of them so why the hate?
Let's not forget regular chapter picture-less books it has characters and they speak and are mentioned at the same time so come on accept mentioned characters, with cameos, and most people appeared in pictures.Cahracter referances count as much as cameos.
I am making a point that files,mentions,Cameos and pictures of character references should be felt like an appearance of a character
