Type changes

Origin HeartGold retypes a number of Pokémon. The tables list the 77 species and forms you can get in the game whose typing differs from the official games. This is how the original Chinese hack works; the English patch changes none of it.

“Official” is the species’ latest official typing (with the Fairy type), so Clefairy being Fairy isn’t an Origin HeartGold change. Some alternate forms, such as Mega Blastoise, keep their official typing even where the base species changed. The Pokémon pages always show the typing you will actually meet. See also Base stat changes.
