Ash ws so excited about this, and decices to go to Grand Harvest Festival along with Iris and Cilan. During their trip to Grand Harvest Festival, Ash and his friend saw a Helioptile, they were confused who's that pokemon. Ash scanned it on his Pokédex, but there's no entry about this Pokémon in this Pokédex, it saids "No data.". Ash and his friends were impressed it didn't scan it at all. Iris was pondering maybe this Pokémon isn't from Unova, and Cilan was pondering maybe it's not from another region, neither. Ash didn't care where it come from, and decices to catch it sending Pikachu to use his Thunder Shock on it. But then, a mysterious woman warned Ash not to attack it, and Helioptile use a new attack called Parabolic Charge on Ash and Pikachu before Iris and Cilan arrives what happened.
