Ash's Glalie was caught as a Snorunt in Hoenn.
Ash caught a mischievous Snorunt whilst traveling through Hoenn. This Snorunt had trouble controlling its Ice Beam attack. Snorunt was used during Ash's battle with Juan but was defeated by Seaking's Hyper Beam. While May was competing in the Grand Festival, Snorunt evolved into Glalie in order to fend off Team Rocket and mastered Ice Beam as soon as it evolved.
Although it was newly evolved when Ash entered the Hoenn League Ash used it in a number of battles where it managed to hold its own successfully, even defeating a Charizard used by Clark. After the league was over he decided to give it a break at Oak's Laboratory. Ash was going to use Glalie against Conway but made a quick change as Conway saw Ash was going to use Glalie.
