Pseudo-Legendaries aren’t an official thing either (at least last I checked?), and yet here we are. At the end of the day, RFakes ended up being a fan-made term for a subsection of Pokémon that evidently do exist; I don’t see what the issue is.Its because they're not a thing. They're not a category, yet people like Khu continued to push this term. Also I just don't like Khu's term in general. Convergant is a better term and not inappropriate like Khu whined about, but either way, there is no specific in game category for these 4 Pokemon.
Not being a fan of the name, or thinking Convergent is a better description is perfectly fine, but to the point of being annoyed that people use the first term coined for them? It seems excessive for no real reason.
