Pokemon Sun & Moon - episode 63 - 21 Feb, 2018

The Mysterious Royal Mask and his partner Incineroar are the stars in the Battle Royal, an Alolan tradition in which four Pokémon battle until the last one standing is the winner. Ash, watching on TV, can't wait to get in on the action—and the next day, he gets his chance! At the Battle Royal Dome, Ash's Litten charges right into the ring, determined to take on the impressive Incineroar. Royal Mask accepts Litten's challenge and invites Sophocles and Kiawe to round out the four. He defeats them all, but Litten is fired up—and during an unexpected rematch the next day, it evolves into Torracat! (Source: Wikipedia)
