Location: Mount Lanakila

Details:
The Move Reminder is possibly one of the most important Move Tutors in the game. Located in Mount Lanakila's Pokémon Center on Ula'ula Island, this character will teach your Pokémon a move that it either had as an Egg Move and has forgotten, or that was long up its Level Up list. This is handy to make sure your Pokémon has the correct moves or if you accidentally deleted a move. It's also got a new feature in Sun & Moon where it will also teach you a move that is further along it's moveset, normally learned at a higher level.

Location: Hau'oli City

Details:
The Move Deleter was previously an important character in past games because he allowed for you to delete HM moves. However, as HM moves aren't in the game, he is now less useful. However, if you want to delete Pokémon's moves, perhaps to have a Last Resort moveset, then you can find him in Hau'oli City's Pokémon Center.
