In Pruning a Passel of Pals!, Kyle had a real major appearance in the episode where he battled Ash and his Buizel in the Battle Stage. He pointed out how the other participants used different Pokémon since the first round and Ash kept on using Buizel. As such, Kyle predicted what Ash was going to do in the match. Despite Ash perfecting Buizel's Ice Aqua Jet technique, it was not enough and Kyle won the match. (Source: Bulbapedia)
