Template:Incomplete synopsis
When J succeeds in capturing Riolu, it is left to Ash and Kellyn to find the unique Pokémon before she can deliver it to her client. With J's ship hidden and with no other leads it is left to Ash's unique sense of Aura and Kellyn's abilities as a Pokémon Ranger to help them find it. Ash and friends are attacked by the client's Pokémon, but manage to save the day and rescue Riolu.
Due to Ash's sensitivity to Aura, which was first introduced in Lucario and the Mystery of Mew, he is able to sense Riolu from far distances, making the movie at least partially canon.
Solana has a different uniform than the one she had in her past appearances. The one she wears in this episode is based on Kate's from Pokémon Ranger: Shadows of Almia.
For an unknown reason, Plusle is not seen with Solana.
This is the second dubbed TV episode to not only retain all of its Japanese background music, but also use no American-made music (unless one counts The Mastermind of Mirage Pokémon as a dubbed TV episode).
