Comic Artist Kyle Baker's X-Spoofs

It's a sign that a form has been established and has its own canons when those involved in its continued creation start to trope and spoof it. Here's an excellent example circa 1989-1999 from Kyle Baker in which a collection of his cartoons poke fun of the by-then mega-popular X-Men characters. This is super-hero comics genre-specific, so if you don't get the in-jokes, you probably have too much back reading to do and should probably just find a geek to explain them to you.
