Count Pumpka is the master of a castle in the Kalos region. He is fat and his appearance resembles a Pumpkaboo. The prince had fallen in love at first sight with Jessie's Pumpkaboo and ordered his butler to invite them to the castle to be introduced and to have a meal. Upon meeting them, Pumpka noticed that Jessie's Pumpkaboo was a truly excellent Bakeccha and that he'd never seen such a big one before.

He then asked Jessie to trade her Bakeccha so that the prince could wed her. Despite initial hesitation, Jessie agreed and traded her Bakeccha for his Kucheat because he told her that it is a Pokémon reported to mega evolve. During the trade process, Jessie's Pumpkaboo evolved into Jessie's Gourgeist. Pumpka then realized that Pumpjin is a trade evolution and the prince liked the way Bakeccha looked better.

After Rocket Gang reveal themselves as the true villians, Pumpka apologized to Clemont and friends for erroneously attempting to take Ash's Pikachu and Clemont's Chespin who was dressed up as a Pikachu for the festival. He then invited them to a meal at the castle to make it up to them.
