I replaced the spider-man image with an image of Foxy from the early days of Warner Bros. As you can see, he's clearly a blatant ripoff of Mickey Mouse. I can't confirm whether they stopped using him out of lack of interest or if Disney asked them to stop. If anybody can elaborate on this, i'll appreciate it.

Knights of the Dinner Table features a group of friends who play tabletop roleplaying games...not Dungeons & Dragons, of course, because that's trademarked. They play Hack Master! ...So does this count as a Captain Ersatz? I think it does, because Hack Master started out as a sort of affectionate parody of D&D and then evolved its own identity (even getting released as an actual game system). There are even Ersatzes of other TSR games; there's a western-themed one that's a takeoff of Boot Hill. So would it fit in this article?

Could someone take out the AVGN Follow The Leader examples? I don't think Internet personalities are allowed to have Captain Erzatzes, at least not in the way that the trope meant.

suedenim, an Expy is a character based on another character who are both created by the same person. The cast of Drawn Together are all (except for Spanky) based on famous cartoon characters, none of whom were created by the guys who made the show. They belong here.

Ok, here at Brazil people use a lot of that. Monica's Gang have a lot of that (specially in their 90's strips and comics) because of Brazilian Law. Like Cebolinha (in English, he's Jimmy Five) in a Horoscope Knights, because at time, Saint Seiya was translated as Zodiac Knights, soooo... There are a lot more, but I just can't recall. It has been a lot of time that I don't read those comics.

Good examples or YMMV?
