Giant Chasm (Japanese: ジャイアントホール Giant Hole) is an area in the northeastern part of the Unova region, and it is much similar to the qualities of a cave, both inside and out.
It is a large impact crater, containing a maze-like forest, and is home to a number of extraterrestrial Pokémon, including the legendary Pokémon Kyurem.
This area has many high-level Pokémon roaming around. It is said that disaster will befall to any person who approaches the chasm, which may explain why Absol can be caught here.
