Albert Einstein asks:

You were right about Meltan…

I am as unsurprised to be proven right as I am unconcerned with the result either way, and equally so, I am pessimistic enough to point out that I was totally wrong (at least, given what we know so far) in predicting that Meltan would need to combine with different Pokémon representing other construction parts like washers, screws and bolts.

Honestly I think it’s sort of a shame Melmetal is just a big pile of hex nuts soldered together; there might have been some interesting “mechanical” (in multiple senses of the word) possibilities to be had with a modular Pokémon.  Melmetal might have several different possible stat profiles or movepool options unlocked by different combinations of “component” Meltan forms.  Of course, I suppose it’s possible that additional secrets will be unlocked in the generation VIII games.
