Sableye shares a close friendship with its Trainer. It is very mischievous, often dragging Uruto into troubles such as provoking other Pokémon. Despite its prankster nature, Sableye is also very observant, able to deduce that Uruto needs personal space such as when the latter becomes bashful around Liko.
Like most of its kin, Sableye has an instinctive attraction to anything that resembles minerals and gemstones, such as Pagogo that it almost attacked out of believing that the Tera Pokémon was made out of gems.
