Ep. 28: Liko y Roy persiguen a Tepen después de que roba la Poké Ball de Rayquaza para venderla.

28

Liko, Roy, and Friede bring Rayquaza's Poké Ball to be inspected by Diana's old friend and adventuring companion, an antique salesman named Tepen, who covertly steals the ball to sell it to another client. Upon noticing the theft, Liko's group pursues Tepen through the town, suspecting he is working for the Explorers. They eventually corner Tepen at a park, where he knocks out Liko and Roy's Pokémon with sleeping powder, but has his entire team defeated by Cap. Diana confronts Tepen, rebuking him for resorting to fraud and thievery, and reminding him of his old passion for adventure. Remorseful, Tepen apologizes to everyone and directs them to his client, who is revealed to be a Poké Ball craftsman. (Source: Wikipedia)
