Rhyhorn

Rhyhorn (Japanese: サイホーン Saihoon) is a /-type Pokémon introduced in Generation I.

Physiology
Rhyhorn is a rhino-like Pokémon that is rock hard. It has spikes on top of it to protect itself from its foes. It walks on four legs and has a horn that can be used as a drill. And it has two toes on each foot and two sharp teeth sticking out of its mouth. The male's horn is longer than the female's.

Natural abilities
Rhyhorn can have the ability Rock Head or the ability Lightningrod. Rock Head prevents Rhyhorn from sustaining recoil damage. Lightningrod directs all -type attacks to Rhyhorn. Its body is clad in a thick hide, and its tackles topple buildings. Unfortunately, it is not very clever, and can only run in straight lines. It is very difficult to catch in Safari Zone due to missing with Safari Balls.

Behavior
Rhyhorn can be very friendly and playful but if approached from behind they may get startled and run as they have a blindspot directly behind them, like horses do.

Evolution
Rhyhorn evolves into Rhydon at level 42.
