The Extreme Hills biome is home to a multitude of Pokémon in Pixelmon. It is an optimal place to find Thunderstone Ore due to the heights that the biome reaches. The biome has several variants, including Extreme Hills Edge, Extreme Hills M, Extreme Hills+, and Extreme Hills+ M, all of which contain a slightly different assortment of Pokémon.
If a Magneton levels up in this biome, it will evolve into Magnezone.
