Move Tutor

The Move Tutor is an NPC residing on Two Island in the Sevii Islands who can teach your Pokemon moves that they've already forgotten or not picked from previous levels. The cost of relearning moves from the Move Tutor is free, however you can only relearn moves that the current evolution your Pokemon is has already been able to learn from levelling up.

Next to the Move Tutor, however, is the Pre-Evolution Move Tutor, which, as the name suggests, allows you to relearn moves from past evolutions of your Pokemon - at a cost of 50k each move. The Pre-Evo Move Tutor doesn't only display past-evolution moves though, so be careful when selecting the move you want to relearn and that it isn't actually one you can learn for free from the normal Move Tutor.

When you arrive on Two Island, head directly right from the Pokecenter and you'll see two houses next to a wooden fence enclosure. The house on the right is home to both Move Tutors.

The Sevii Islands can be accessed by first speaking to Bill in front of the Cinnibar Island Gym to travel to Island One, then once again to travel to any of the other Sevii Islands.
