Transform (Japanese: へんしん Transform) is a non-damaging Normal-type move introduced in Generation I. It is notable for being the only move of Ditto despite never being a signature move, because Mew can also learn it.

Effect

151Mew.png This move effect may be in need of research.
Reason: Are PP Ups taken into account for maximum PP displayed for a transformed Pokémon in Generation I and II?
You can discuss this on the talk page.

Generation I

Transform changes the user's current type, current stats, current stat modifications, current moves, current species, and current cry to that of the target's.

Each move copied by Transform will have 5 remaining PP of the usual maximum. With this in mind, if a Ditto encounters another Ditto in this game, both Ditto will continually Transform into each other, replenishing the 5 PP constantly and making the battle seemingly endless. PP-restoring items like Ethers used from the Bag can only restore PP to moves the Pokémon knows before transforming.

Transform does not copy the target's status conditions, level, current or maximum HP, base experience, palette colors or the generic minimize image. If a transformed Pokémon takes damage from a critical hit, its original stats will be used rather than its stats after Transform. The probability of a transformed Pokémon scoring a critical hit is based on the original Pokémon's base Speed, not the base Speed of the Pokémon it transformed into.

Transform bypasses accuracy checks to always hit, even during the semi-invulnerable turn of a move such as Dig or Fly.

In-game, if a wild Pokémon uses Transform and is subsequently caught, it will become a Ditto, regardless of what species it originally was. It will then have all the stats and moves of a Ditto, except for its current HP, which will remain unaltered by this change.

If a wild Pokémon uses Transform twice and is subsequently caught, its DVs will be the DVs of the first Pokémon it transformed into.

In Stadium, Transform will not work if the target's current species is Ditto.

Generation II

Transform, if used by a Shiny Pokémon, will cause the Pokémon species transformed into to appear Shiny. Likewise, a normal Pokémon transforming into a Shiny target's species will appear as a normal version. A transformed Pokémon retains its original species for determining if it is boosted by Pokémon-specific stat-enhancing items, with the exception of Metal Powder, which uses the target's species.

If a Pokémon transforms into a Pokémon that knows Sketch, Sketch will have its maximum 1 PP rather than 5 like other moves.

Transform will now fail if used on an opponent who has already transformed or if they are in the semi-invulnerable turn of a move such as Dig or Fly. Wild Pokémon are now treated as their original species upon capture after transforming, rather than being treated as Ditto like in Generation I.

Transform will correctly copy Unown's letter.

Generation III

151Mew.png This move effect may be in need of research.
Reason: Interaction with Deoxys's forms in link battles between games in which Deoxys has different forms
You can discuss this on the talk page.

Transform copies the target Pokémon's Ability, replacing its own. Starting in this generation, Transform also copies the base experience and the EV yield of the target.

Leppa Berries used from the Bag or as a held item can only restore PP to moves the Pokémon knows before transforming. A held Leppa Berry will only be consumed if a move known before transforming reaches 0 PP. The maximum PP of a move known due to Transform is the move's base maximum PP, regardless of any PP Ups used by the target.

If a Pokémon transforms into a Pokémon with multiple forms, it will copy the form of the target. If a Pokémon transforms into a Castform and has the Ability Forecast, it will change form depending on the weather after transforming into Castform's current form.

During a Pokémon Contest, the Pokémon will transform into one of the other contestants.

Generation IV

151Mew.png This move effect may be in need of research.
Reason: If a Pokémon transforms into Giratina in the Distortion World, does it remain in Origin Forme regardless of held item?
You can discuss this on the talk page.

Transform now copies the target's coloration; whether or not the transformed Pokémon is Shiny depends on whether the target is, not the user.

A held Leppa Berry will be consumed if the Pokémon runs out of PP for a move it knows due to Transform. If a Leppa Berry is consumed via Bug Bite, Pluck or Fling, it will restore PP to a move known due to Transform. A Leppa Berry consumed as a held item, or via Bug Bite, Pluck or Fling, can restore a move's PP above the 5 Transform gives, as long as it doesn't exceed the move's maximum PP.

If a Pokémon transforms into Origin Forme Giratina or Arceus, the Pokémon first transforms into the target's current form, then immediately changes to the form corresponding to its own held item; therefore, if it transforms into an Arceus but holds a Plate, it will first assume the target Arceus's form, then immediately change to the form corresponding to its own Plate. If a Pokémon transforms into Cherrim, it will change form depending on the weather. If a Pokémon transforms into Sky Forme Shaymin, it will change to Land Forme if it is frozen.

As in previous generations, a transformed Pokémon retains its original species for determining if it is boosted by Pokémon-specific stat-enhancing items, with the exception of Metal Powder and Quick Powder, which use the target's species.

During a Pokémon Super Contest, the Pokémon will transform into one of the other contestants.

Generation V onwards

Transform no longer copies the target's catch rate. Transform will now fail if used by a Pokémon that is already transformed, targeting a Pokémon behind a substitute, or targeting a Pokémon under the effect of Illusion.

A move known due to Transform now always has a maximum of at most 5 PP, regardless of the move's base maximum PP if it is greater than 5. As such, a Leppa Berry cannot restore the PP of a move known due to Transform above 5.

A transformed Pokémon can no longer change forms. It will remain in the form the target was in when the user transformed into it. For example, if a Pokémon transforms into Castform, it will not change form even if the weather changes.

Imposter, Ditto's signature Ability introduced in Generation V, automatically causes the user to transform into the opponent.

Pokémon that know Transform are banned from participating in Pokéstar Studios films.

The user will transform into Mega-Evolved Pokémon and maintain the form regardless of whether it holds the required Mega Stone. This has no effect on the restriction that only allows each player one Mega Evolution per battle.

A transformed Pokémon can use Z-Moves exclusive to a species it has transformed into, if it holds an appropriate Z-Crystal. If the user has transformed into a Mega-Evolved Pokémon, it cannot use any Z-Moves, even if it holds an appropriate Z-Crystal.

Transform will fail if used on a Pokémon that is protected by Crafty Shield.

In Pokémon Contest Spectacular, if Transform is used, a Substitute doll would be thrown in the stage. The user would then transform into the doll. The effects of Transform will last for the round it is used in.

Even if a Pokémon transforms into Meteor Form Minior, Shields Down will not prevent a transformed Pokémon from being afflicted with status conditions.

If powered up by a Normalium Z into Z-Transform, the user's HP is fully restored.

If the user transforms into a Pokémon that has no type (i.e. it was a pure Fire type that used Burn Up), the user will become Normal-type; if such a target has additionally been affected by Forest's Curse or Trick-or-Treat, the user will become Normal-type with an added Grass or Ghost type respectively. If the user transforms into a dual-typed Pokémon that has used Burn Up, however, Transform will copy the target's current types (and type additions) as usual.

Oddities

Because Transform takes on the exact form of the Pokémon transformed into, strange things can occur when a Pokémon uses the move to become another. Specifically, Pokémon with multiple forms cause the transforming Pokémon to behave oddly.

Gastro Acid

If the Pokémon that is Transforming has previously had Gastro Acid used on it and then subsequently uses Transform without switching out beforehand, the Pokémon that it transforms into will not regain its Ability, and thus will not change forms if the Ability of the Pokémon transformed into causes this.

Origin Forme Giratina

In Generation IV, when a Pokémon transforms into Origin Forme Giratina, they will retain this form only briefly, and then will revert to Altered Forme. This is because only Giratina can hold the Griseous Orb, which forces this form outside of the Distortion World. Note that if the player is able to have a Pokémon that can transform when battling Giratina for the first time in the Distortion World, that Pokémon will be able to retain its transformation into Origin Forme (due to being inside of the Distortion World).

In contrast, in Generation V, when a Pokémon transforms into Origin Forme Giratina, it will retain the Origin Forme.

Shaymin

If a Pokémon transforms into Shaymin in its Sky Forme and is then frozen, it will stay in Sky Forme despite this normally causing a Shaymin to revert to Land Forme.

Arceus

In Generation IV, when a Pokémon transforms into Arceus, it will become Arceus in its Normal form, unless it is holding a Plate. Holding a Plate, the transformed Pokémon will at first take Arceus's current form, and then subsequently transform into the alternate form dictated by the Plate.

In contrast, in Generation V, when a Pokémon transforms into a Plate-holding Arceus, it will retain the Arceus's appearance and type, but Judgment will remain Normal unless the transformed Pokémon is holding a Plate itself, as the move copies the Plate's type rather than the holder's.

Transform loop

In Generation I if Ditto (or another Pokémon with only Transform) faces another Pokémon with Transform in a Trainer battle where neither Trainer has any items and no Pokémon besides the Pokémon with Transform, the battle will never end. This is because when Transform is used, the Pokémon will turn into its opponent, resulting in a Transform moveset of, again, only Transform. Since every time Transform is used, it gives the Pokémon using it the target's moveset with 5 PP each, Transform will continue to Transform into itself, restoring the PP every time it is used. Due to this, one will never reach a point where it can only use Struggle, unlike Wynaut and Wobbuffet in later generations who, although they too have no directly damaging moves, will eventually run out of PP and thus be able to use Struggle. This is likely why few Trainers have Ditto in the Generation I games.

This issue is not present in any other games because of a change in Transform mechanics: from Generation II onwards, it is not possible to Transform into a Pokémon that is the Transformation of another Pokémon.

PP restoration

While transformed, any attempt to use a PP restoring item on the moves acquired during transformation will fail. However, if the transformed Pokémon is holding a Leppa Berry, a copied move low on PP will be restored.

Glitches

--

Main article: -- (move)

In Generation I, if a Pokémon transforms into another Pokémon that knows more moves and, while transformed, switches the position of the move in the slot of a legitimate move and one which should contain no move, after reverting to its original form, it will have access to the glitch move --.

Ditto glitch

Main article: Mew glitch

The primary method of the Mew glitch involves having a wild Ditto transform into the player's Pokémon, as this copies the Special stat, which is used to modify the species of Pokémon encountered.

Transform assumption glitch

In Generation I and II, any Pokémon that uses Transform is regarded as a Ditto in its new form; this means that if the player catches a Mew or a glitch Pokémon which has used the move Transform, or a Pokémon which has used Transform via Mirror Move, instead they will obtain a Ditto. Mew turning into Ditto was not an issue in these games because a wild Mew could not be legitimately encountered, but this system was changed in Generation III where it could.

Shiny Ditto glitch

Main article: List of glitches in Generation II → Shiny Ditto DV manipulation

The Shiny Ditto glitch requires a game from Generation I and Generation II, but only has an effect on a Generation II game. In Generation I, if a Pokémon uses the move Transform while already transformed, after being caught it will retain the IVs of the Pokémon it transformed into. Due to Shininess being determined by IVs in Generations I and II, this allows the player to make a wild Ditto Shiny by having it use Transform while already Transformed; this can be accomplished by either having a Shiny Pokémon that knows Transform (Mew, certain glitch Pokémon, or another Ditto), or by teaching a Shiny Pokémon Mimic, then having the wild Ditto use Mimic on the move Transform. While Shiny Pokémon do not exist in Generation I, due to being determined by IVs, this Ditto will be Shiny when traded to Generation II.

Sketch glitch

Main article: Sketch glitch

In Generation II, if a Pokémon uses Sketch while transformed, it will permanently learn the Sketched move.

Transform held item glitch

Main article: List of glitches in Generation IV → Transform held item glitch

In Japanese versions of Diamond and Pearl, if a Pokémon holding an item uses Transform and has its item stolen, as long as it does not faint before the end of the battle, both the transforming Pokémon and the thief will retain the item after the battle.

Mimic glitch

Main article: Mimic glitch

In Japanese versions of Pokémon Diamond and Pearl, if a Pokémon uses Transform via Mimic then faints, it will keep the moves it learned via Transform.

Rage glitch

Main article: Rage glitch

In Generation IV, if a transformed Pokémon uses Rage and causes the message "Rage is building" to appear, then defeats or captures the opponent, the Pokémon will permanently learn the moves it knew while transformed.

In other games

Pokémon Mystery Dungeon series

Transform causes the user to take only the form of a random hostile Pokémon on the dungeon's floor. It does not copy that Pokémon's moves, type combination, Abilities or stats. It has only 1 PP, leaving the user only the basic attack and Struggle left to use (unless the user knows moves other than Transform).

Trivia

  • In the German version of the Generation II games, this move was renamed from Wandler into Verwandler. The reason for this is unknown. Even though the difference in meaning is minimal, this change was retracted in the following generations.
  • Transform is the only way to see the battle animation of Cherrim's Sunshine Form prior to Generation V, as Cherrim sent from a Poké Ball will always be sent out in Overcast Form, and Cherrim is not available in the wild in Generation IV. A Ditto that transforms into Cherrim, however, will play the animation of the alternate form if it escapes from a thrown Poké Ball.
  • With the help of Transform, Pokémon can legitimately have more than 510 total effort values: if the target has EVs in some stats beside HP and the Transform user has EVs in HP, after transforming the total number of its EVs can exceed 510 due to HP not being copied.
