So Mimikyu theory you may not like: it’s always been weird to me that ALL Mimikyu dress like Pikachu, especially since Pikachu never struck me as universally popular in-universe as it is in real life, at least not to the point where EVERY Mimikyu would base itself on it. But what if that’s the point? What if Mimikyu is breaking the fourth wall and is, for lack of better phrasing, meant to be self-aware? After all, it’s a ghost type, and in some psychological horror games there are characters that become “aware” of the player and even obsessed with them (yandere style). Maybe Mimikyu is meant to reflect that as a ghost Pokémon that’s aware of the real world and wants to appeal to players and not necessarily in-universe characters. The anime characterizes it differently, with Jessie’s having its own motivations, but that IS a different canon and GF might have had different intentions (and it’s not like the games ever avoided breaking the fourth wall). I have a feeling you’re not into fourth wall breaking as it completely ignores in-universe lore, but what are your thoughts on this reasoning?

Well, I’m not sure all Mimikyu do dress like Pikachu, actually – just the ones we’ve seen.  The Sun and Moon website actually claims that it’s a recent phenomenon, so Mimikyu in the past must have looked like something else, or simply never revealed themselves to humans at all.  Mimikyu seems to me like a Pokémon that’s ripe for regional variation, with other forms imitating other locally popular Pokémon, or even inanimate objects.  But then again, the website’s reason for Mimikyu dressing like Pikachu is itself very fourth-wall-break-y; it claims that they picked Pikachu because of “the rising popularity of Pikachu-styled merchandise around 20 years ago.”  Sun and Moon were released twenty years after Red and Blue, the first Pokémon games, so it seems like this is referring to the real worldwide Pokémon boom of 1996-1999 (especially given that the internal chronology of the core games – to the extent that there even is one – is not real-time; we know that generations III and IV are contemporary with I and II, while Blue and Red the characters are in their early 20s at most when they appear in Sun and Moon).  I’ve also never really had the sense that Pokémon is particularly averse to breaking the fourth wall.  So I guess my answer is… mayyyyyybe?
