Yeah, Bulbapedia is an impressive wiki. I mean, usually when you get a fan wiki for a series, it's pretty empty or has a lot of content missing or doesn't get updated all too much, but the people working on this one are managing to cover just about everything you can think of (that relates to the Pokemon series).

But that seems to be a typical trend for the more popular NIWA wikis. Super Mario Wiki and Zelda Wiki are also extremely comprehensive when it comes to coverage of their respective franchises. Perhaps a little too much so in some cases, like the list of implied Mario characters over on Mario Wiki:
