Shun was on a train with Sylvan, Taka, and Kako. He met up with Ash, Brock, Dawn, Shaymin, Layla, and Moose and listened to Moose's story of how he witnessed Shaymin's flower bearing once. During this, he teased Kako that Shaymin might bite when she commented on how cute it was. Shortly after, he witnessed Shaymin transform into its Sky Forme.
Following this, the train was attacked by Zero's Magnemite, Magneton, and Magnezone, but Ash, Dawn, and Shaymin were able to drive them off. He later said his goodbyes to Ash, his friends, and Shaymin as they set off on a ferry to Gracidea.
