Dino is a recurring character in the Pokémon: Black & White series.
Season 14: Black & White
He participated in the Club Battle tournament and won in a battle against Omega and advanced to the second round. He later battled against Antonio in the second round and defeated him. He advanced to the semi-final round with Ash as his opponent. However, in the next episode, Darumaka was quickly defeated by Ash's Palpitoad, eliminating him from the tournament.
Tranquill first appeared in The Club Battle Hearts of Fury, Emolga Versus Sawk! where it was used against Antonio’s Cottonee in the quarter-finals. Having a type advantage, Tranquill easily knocked out its opponent, allowing Dino to move on to the semi-finals.
Upon reaching the semi-finals, Dino learned he was to battle Ash next and chose to use Darumaka during the match, where it was sent out against Ash's Palpitoad. However, it was defeated with a single Hydro Pump.
