User blog:Wolverine-Man/What's with these categories?

Hey, guys. It's Wolverine-Man here. I literally just discovered these new categories. For example, on the Ganondorf vs Godzilla page which I also recently discovered, there were these categories named "Ganondorf" and "Godzilla". But those aren't the only ones I discovered. There's also "Little Mac", "Balrog", "Street Fighter", and "Nintendo" on the Little Mac vs Balrog the page, which I also just found. First of all, we already have the Street Fighter and Nintendo characters categories. Second, what's the purpose of creating categories named after fictional characters? Is it just because those characters are the participants of their respective fan-made battles or something? Does that mean I have to add "Cell" or "SCP-682" or etc to my own battles? I hope not, because that would take forever. I just wanted to ask why these categories exist and I would like an explanation.
