Gliscor resembles a half scorpion/half vampire bat creature. Like Drapion and Skorupi, Gliscor has barbed stinger on its tail. Due to the stiffness of its wings it needs to have the wind at its back in order to stay airborne.
They are very rare to find in the wild but they live in pine forests and swamps.
Gliscor is the evolved form of Gligar. In the game you get it by leveling up a Gligar when it is holding a Razor Fang at night.
Gliscor first appeared Riding the Winds of Change where Paul captured it. In DP085, Ash fell off of a cliff, and his Gligar evolved into a Gliscor so it could save Ash. Paul's Gliscor is voiced by Yuji Ueda, and Ash's Gliscor is voiced by Katsuyuki Konishi who also voiced it as a Gligar.
Gliscor might be a combination of a scorpion and a bat due to its bat-like ears and wings. Despite it's species: Fang Scorp Pokémon.
