Color Swap Pokémon ^#352

Its color changes for concealment and also when its mood or health changes. The darker the color, the healthier it is.

- Color-Change
  Whenever this Pokémon takes damage from a move, the Pokémon's type changes to match the move. If the Pokémon has two types, both are overridden. The Pokémon must directly take damage; for example, moves blocked by a substitute will not trigger this ability, nor will moves that deal damage indirectly, such as spikes. This ability takes effect on only the last hit of a multiple-hit attack. In Pokémon Colosseum and XD: Gale of Darkness, this ability does not take effect on Shadow-type moves.

- Protean
  Changes the bearer's type to match each move it uses. The type change takes place just before the move is used.
