A move tutor is a non-player character who will teach a Pokémon moves that are not normally able to be learned through level up, TMs, or HMs. These characters are scattered across Hadysium.
Unlike most games, there is no "cost" to teaching your Pokémon moves. You are usually asked to complete a simple task and then you have access to the tutor's moves. There are no limitations on the number of times you can teach a particular move.
Simone - "The Blind Witch"Edit
Simone resides in a small house east of Thistle Town near the Abandoned Coal Mines. She practices dark magic with her Vulpix and Stunky at her side. She lost her visions years ago. Some say she may be immortal. She loves visitors though and will offer them a place to rest.
She will teach your Pokémon her moves if you bring her a Zubat caught in the Abandoned Coal Mines. After defeating the Elite Four, she will offer you a Zubat with the move Brave Bird as a congratulatory present.
Hiei - "The Aspiring Dojo Master"Edit
Lars - "The Fossil Maniac"Edit
Aphrodite - "The Lonely Heiress"Edit
Carmen - "The Beautiful Contest Master"Edit
Tyrone - "The Headbutting Aficionado"Edit
Wallace - "The Hoenn League Champion"Edit
Falkner - "The Violet City Gym Leader"Edit
Britney is the Champion of the Hadysium Pokémon League. She is also the reigning pop star whose music is currently dominating the charts. She has taken a liking to the hero and is willing to aid them in anyway - besides forfeiting a match. She can be found at her home in Cottonwood Town.
She will only teach you her special moves if you have defeated her at the Pokémon League and have completed the objectives set out by the other Move Tutors (other than Pietro).
Pietro - "The Mysterious Monk"Edit
Not much is known about Pietro. In fact, you're the first person he has revealed his name to. He "resides" at the top of the Nova Lighthouse.
He will only teach you his moves if you defeat him in battle.
Unlike the other Move Tutors, each move he has can only be taught once. He will only teach fully evolved Pokémon with the Effort Ribbon his moves.
