Gliscor was caught as a Gligar that was afraid of heights and couldn't fly very well.
Gliscor wanted to be in the action too, but Ash said refused and learned Fire Fang in the same episode. Ash used Gliscor in the Canalave Gym, where it defeated Byron's Bastiodon and in the Snowpoint Gym, where it lost to Candice's Snover. Ash also used Gliscor to battle Paul's Torterra. It nearly defeated Torterra, but lost to Torterra's Frenzy Plant.
Ash summoned Gliscor from McCann in order to battle Paul in the Sinnoh league. Gliscor had perfected Giga Impact and while training with McCann, learned Stone Edge. During Ash's battle with Paul, Gliscor battled Ninjask but was unable to overcome Ninjask's speed and was recalled after Ninjask knocked it into the ground, causing it to become poisoned by Drapion's Toxic Spikes. Gliscor later battled Drapion and defeated it using Fire Fang. However due to its exhaustion and the fact that it poisoned, Gliscor was defeated by Paul's Electivire.
Gliscor is assumed to be at Professor Oak's Laboratory. However it is possible that Gliscor may have returned to McCann for more training.
Gliscor was planned to reappear along with all of Ash's Pokemon in an upcoming episode of Best Wishes Season 2, but was eventually scrapped. Still, it does appear in the opening scene of BW: Adventures in Unova.
