This Gliscor is a Ground/ -type Pokémon that Paul caught in Sinnoh.
Gliscor was leading a group of Gligar and causing havoc throughout Veilstone City, so Paul decided to catch it using his Electabuzz and Weavile. After checking Gliscor's stats, he kept it.
Paul used Gliscor once in a battle against Ash. Gliscor easily beat Ash's Gligar by using Guillotine.
Gliscor was also seen briefly in Aiding the Enemy!, but has not been seen since. It is currently residing with Reggie prior.
