Mr. Mime has often been considered one of the least beloved Pokémon of the first generation, although he certainly still had his fans. Detective Pikachu gave us a weird but hilarious take on Mr. Mime, and now Pokemon Sword and Shield has introduced an all-new Galarian Mr. Mime. Not only did they give us a new Mr. Mime, but he also received a brand new evolution for the very first time.
How to evolve Mr. Mime into Mr. Glaquette
Mr. Mime was originally reintroduced in Pokemon Red and Blue as a Psychic-type Pokemon before later being transformed into Psychic/Fairy when this new typing was introduced in Gen 4. This generation also brought pre-evolution for Mr. Mime with Mime Jr., but the Pokemon never received an actual evolution. Technically, Mr. Mime himself still doesn't evolve, but the new Galarian Mr. Mime does with Mr. Glaquette.
We've already covered how to find a Galarian Mr. Mime in another guide, so the focus in this guide is on how to evolve this new form into Mr. Glaquette. Galarian Mr. Mime is a Psychic/Ice type Pokémon and its evolution is quite simple, as all you have to do is keep leveling up until it reaches 42. Once it reaches 42, it will evolve into M. Glaquette.
Considering the end of the game you should catch Galarian Mr. Mime, it is very likely that he will already reach level 42. In this case, increase him by one more level and he will become Mr. Glaquette at this time -the. Mr. Glaquette also learns Psychic at level 48, so be sure to try and evolve him before that or you'll have to go find the Move Booster.
