Onix () is the 95th Pokémon in the Pokédex. It is a Rock/Ground Type, and is known as the Rock Snake Pokémon.
Onix can have one of two abilities: Rock Head, which prevents this Pokémon from receiving recoil damage from recoil-causing moves; or Sturdy, which gives this Pokémon an immunity from falling to a One-Hit KO move such as Fissure or Horn Drill, and starting with Generation V, Pokémon with Sturdy cannot be KO'd in one hit when it has full HP. Onix's Hidden Ability is Weak Armor, which lowers the Pokémon's Defense by one stage but increases its Speed by one stage whenever it is hit by an attack.
Onix is in the Mineral Egg Group, and it takes approximately 6,400 steps for its Egg to hatch. It takes Onix One Million Experience Points to reach Level 100.
Onix is a large rock snake with a spike-like fin on the top of its head.
 Gender Differences
Onix doesn't have any visible characteristics to differentiate between male and female.
