Pierced: A Pokemon Story

After returning to Kanto after a league win in Alola, Ash's friends wants to meet him again. Without telling Ash or Delia, they all came to Pallet Town for a Reunion and Champion Party. Since Ash was tired from all that championship (Since he didn't slept the night before the championship to practice) He slept in the plane for 8 hours. But a big terror was waiting for him in the party.
