Ninjutsu (Ability) - The user changes types to match that of whichever move it uses, with similar function to the
Protean ability, and also raises the
priority and accuracy of all moves by one stage each;
Hydro Pump;
Ice Beam;
Gunk Shot;
Dark Pulse;
Hidden Strike (Dark-Type; Physical; 90 Power; 10 PP; 100% Accuracy) - The user "disappears into the shadows" on the turn this attack is used, rendering the user semi-invulnerable, before dealing damage in the second turn, ignoring and breaking any defensive measures set up by the target, thereby functioning similarly to
Phantom Force in both regards. Though it is considered a Dark-type Physical attack, this attack deals damage based on the following two conditions:
- The lower of the target's Defense and Special Defense, dealing damage as a Physical attack if Defense is lower or as a Special attack if Special Defense is lower, or randomly if both stats are identical; this also takes into account modifications to the target's Defense and Special Defense through moves such as Bulk Up or Bug Buzz and abilities such as Marvel Scale, as well as modifications to the user's Attack and Special Attack through moves such as Swords Dance or Superpower and abilities such as Intimidate;
- The greatest move type weakness of the target, selecting a random valid type to deal damage as if multiple types are valid for this purpose; 4x type weaknesses are prioritised first, followed by 2x type weaknesses if the target has no 4x weaknesses, and then by types which the target does not resist if they also possess no 2x type weaknesses.
For both conditions, calculations are performed on the second turn of the attack before damage is dealt, thereby taking into account any modifications made to the target's statistics, type, or type weaknesses and resistances, as well as if the target of this attack changes as a result of the initial target being swapped out for a different Pokémon. With regards to abilities such as Protean or Ninjutsu, which change the user's type based on the user's move that turn, the user's type will change to Dark on the first turn of this move before the move is used and the user becomes semi-invulnerable, and on the second turn will change to whatever type has been selected as the damage type for this move after the above calculations, but before damage is dealt, meaning this move will still receive STAB as usual regardless of the type it acquires.
