Certain special Move Tutor moves are distinguishable from other Move Tutor moves because they are exclusive to a single Pokémon or a certain explicitly-defined class of Pokémon. Notably, these are the only Move Tutor moves that Mew cannot learn.
Variations of Hyper Beam
Introduced in Generation III, Frenzy Plant, Blast Burn, and Hydro Cannon can only be taught to fully-evolved Grass-type, Fire-type, and Water-type starter Pokémon, respectively, if their friendship is maximized.
In Pokémon FireRed and LeafGreen, these moves could only be taught to Venusaur, Charizard, and Blastoise, respectively, and could only be taught once. In later games, they can be taught multiple times and to any fully-evolved starter Pokémon.
In Pokémon FireRed and LeafGreen, these moves are taught by a woman on Boon Island's Cape Brink. In Pokémon Diamond, Pearl, and Platinum, they are taught by a Move Tutor on Route 228. In Pokémon HeartGold and SoulSilver, they are taught by a Move Tutor in Blackthorn City. In Pokémon Black and White, they are taught by a Move Tutor on Route 13, who moves to the Pokémon World Tournament in Pokémon Black 2 and White 2.
Introduced in Generation IV, Draco Meteor can be taught to any Dragon-type Pokémon (including Arceus holding a Draco Plate). In Generation IV, its friendship must be maximized, but this is not required in later games.
It is taught by Grandma Wilma, who is found on Route 210 in Pokémon Diamond, Pearl, and Platinum or in Blackthorn City in Pokémon HeartGold and SoulSilver. In Pokémon Black and White, it is taught by the Gym Leader of Opelucid City from the opposite version (DraydenW or IrisB), while Drayden teaches it in both Pokémon Black 2 and White 2.
Introduced in Generation V, the Pledge moves can be taught to any starter Pokémon of any evolution stage.
They are taught by a man in Driftveil City in Pokémon Black and White or at the Pokémon World Tournament in Pokémon Black 2 and White 2.
Introduced in Generation V, Secret Sword can only be taught to Keldeo. It is Keldeo's signature move and, in Pokémon Black 2 and White 2, knowledge of Secret Sword will change Keldeo from Ordinary Form to Resolute Form.
Keldeo can only learn the move in Pokémon Black and White when the remaining Swords of Justice are also in the party. When the four are brought to the Moor of Icirrus, the trio will teach Keldeo the move. It can also be learned by Keldeo in the Pledge Grove in Pokémon Black 2 and White 2.
Introduced in Generation V, Relic Song can only be taught to Meloetta. It is Meloetta's signature move and, when used in battle, will cause it to change between its Aria and Pirouette Formes.
Relic Song can be taught to an event Meloetta in Pokémon Black and White and Pokémon Black 2 and White 2 by a Musician in Castelia City's Café Sonata.
