Type Changing

The move Soak is a relatively simple move. With it, you can take your opponent and submerse them in water, thus making them a pure Water-type, removing all of their type combinations and immunities. It also removes any Same-Type-Attack-Bonus they would have received from the moves in their moveset. This will allow you to fully hit in with Grass & Electric-type moves to damage the opponent.

Name	Type	Cat.	PP	Att.	Acc.	Effect
Soak			20	--	100	It bathes the opponent in lots of water and makes their type Water.

The move Forest's Curse is a relatively simple move. With it, you curse the Pokémon and add the Grass-type to them. This will make Single typed Pokémon Dual-typed and Dual-typed Pokémon Triple-typed. As such, the Pokémon's type calculations will be altered. The Pokémon gains all the benefits and hinderances of the Grass-type, including immunity to Leech Seed, Grass-type STAB and the various other bonuses. It fails if the target is already Grass-type

Name	Type	Cat.	PP	Att.	Acc.	Effect
Forest's Curse			20	--	100	The user puts a forest curse on the target. Afflicted targets are now Grass type as well.

The move Trick-or-Treat works identically to the Forest's Curse move. With it, you curse the Pokémon and add the Ghost-type to them. This will make Single typed Pokémon Dual-typed and Dual-typed Pokémon Triple-typed. As such, the Pokémon's type calculations will be altered. The Pokémon gains all the benefits and hinderances of the Ghost-type, including ability to retreat from battle if restricted by an ability, and immunity to Normal and Fighting-type moves. It fails if the target is already Ghost-type

Name	Type	Cat.	PP	Att.	Acc.	Effect
Trick-or-Treat			20	--	100	The user takes the target trick-or-treating. This adds Ghost type to the target's type.

The move Magic Powder works akin to the move Soak in that it completely replaces a Pokémon's type. In this case, it makes them a Psychic-type. However, this move is also a Powder move so cannot work on Grass-type Pokémon.

Name	Type	Cat.	PP	Att.	Acc.	Effect
Magic Powder			20	--	100	The user scatters a cloud of magic powder that changes the target to Psychic type.

Pokémon Scarlet & Violet introduced the new mechanic, Terastallization. This mechanic allows for you to change the type of your Pokémon to your specific Tera Type. This overwrites both of your current types.

You have the ability to change your Pokémon's Tera Type to any of the 18 types in Medali.

Moves that change the Pokémon's type will fail when used by or used against Pokémon of Tera Types.

Burn Up is a move introduced in Sun & Moon with an interesting twist. While it is a powerful Fire-type move, when a Pokémon uses it they will lose their Fire-type. This means if they're dual-typed, they'd become single type. If they are pure Fire-type normally, they will then become typeless with no weaknesses. This effect is removed on switch out and the move will fail if it is used by a Pokémon that is not a Fire-type, including those that are now typeless.
In Scarlet & Violet, an Electric-type variant of this move was introduced, Double Shock. It had the same effects as Burn Up.
With Tera Type Pokémon, if the Pokémon trying to use the move are not the type of the move, it will fail. However, if they are of the same Tera Type, they will continue being that type.

Name	Type	Cat.	PP	Att.	Acc.	Effect
Burn Up			5	130	100	To inflict massive damage, the user burns itself out. After using this move, the user will no longer be Fire type.
Double Shock			5	120	100	The user discharges all the electricity from its body to perform a high-damage attack. After using this move, the user will no longer be Electric type.

Camouflage was originally a Staryu only move, but has since been learned by various other Pokémon. Camouflage will change the type of the user to a type depending upon the terrain in which it battles. In-game, this is highly useful. However, in the multiplayer, it is rather limited as it will always be within a building. The places and types are as follows

Name	Type	Cat.	PP	Att.	Acc.	Effect
Camouflage			20	--	--	The user's type is changed depending on its environment, such as at water's edge, in grass, or in a cave.

Conversion is a move introduced within the first generation and thus the first move which actually changed the type of the Pokémon. Conversion changes the user's type to the type of the first of its four moves. This will allow you to get the Same-Type-Attack-Bonus from these moves. However, as you don't have control over it, it will be completely random.

Name	Type	Cat.	PP	Att.	Acc.	Effect
Conversion			30	--	--	The user changes its type to become the same type as one of its moves.

Conversion2 is a move which was introduced in the second generation to randomly change the type of the user. Unlike the above move, the type the user becomes varies. The user will become a type resistant to the type of the move that hit it so if it got hit by an Electric-type move, it may become a Ground-type. However, it can't make the user the same type as it already is, so if that would occur, the move will fail. Click here to consult with our Type Chart

Name	Type	Cat.	PP	Att.	Acc.	Effect
Conversion 2			30	--	--	The user changes its type to make itself resistant to the type of the attack it last took.

Reflect Type is a move introduced within Generation V which allows for the user to take the complete type of the target Pokémon. This includes both types so can turn Mew from a Psychic Pokémon to a Dragon/Fire if it's against Reshiram or basically any type it is battling against. This can also be done Double & Triple Battles, by targetting your allies instead of your opponent, that way your Pokémon shall receive their type.

Name	Type	Cat.	PP	Att.	Acc.	Effect
Reflect Type			15	--	--	It reflects the opponent’s type and becomes the same type.

Color Change is a simple ability known only by Kecleon. This ability will change Kecleon's type to the type of the move that previously hit it. This gives Kecleon a tactical advantage against Pokémon who use single type moves. In Generations III & IV, this ability changed Kecleon's type with each hit on multi-hit moves, but with Black & White, this was removed and Kecleon only changes type after the final hit has occured.

Mimicry is a new ability known by Galarian Stunfisk. This ability allows Stunfisk to change its type depending on the current terrain. If Electric Terrain, it becomes Electric-type. If Grassy Terrain, it becomes Grass-type. If Psychic Terrain it becomes Psychic-type and if Misty Terrain it becomes Fairy-type.

Protean is a new ability that is able to be had by Kecleon, Froakie, Frogadier and Libero by Scorbunny, Raboot and Cinderace. This ability will change the type of the Pokémon into the type of the move it is using, just before it uses it. This makes it a pure Pokémon of that type, and gives it STAB from the moves it uses. It also messed with any strategy that the opponent may have.
