It is not known to evolve into or from any other Pokémon.
Pinsir is a bipedal Pokémon that has a brown body with a large pair of white horns/pincers that are dotted with small spikes. Pinsir has short legs with three toes each and skinny, three-clawed arms. Its mouth has long, flat teeth that are arranged horizontally rather than vertically. Pinsir is cold-blooded.
Pinsir's horns/pincers have enough crushing power to shatter thick logs and allow it to lift things twice its own weight. Its horns are very flexible, and are capable of being launched downwards.
Pinsir's movements are more sluggish when exposed to cold weather, so they hide in burrows, treetops or tree roots during chilly nights. Pinsir are known to dig holes with their horns to sleep in. However, when they are fully awake, they can be quite aggressive.
Much like Heracross, Pinsir seem to enjoy tree sap. As a result they often compete with Heracross over trees with the best sap. Pinsir also eats prey, gripping it with its pincers until the prey is torn in half.
This Pokémon was unavailable prior to Generation I.
