Pokémon : S21 | E34 – Guiding an Awakening!

Following Ash's victory at the Abandoned Thrifty Megamart, Nanu agrees to battle him in a grand trial! But there's a catch—Ash must defeat three of Nanu's Pokémon using only one of his. He chooses Lycanroc, whose training has paid off, as it quickly defeats Nanu's Krookodile. Next up is Sableye, and Lycanroc lands another win. But when Nanu sends out his Alolan Persian and begins taunting Ash, Lycanroc's temper begins to flare—leading Ash to realize that Lycanroc is channeling that anger into power! Determined, Lycanroc learns the move Counter and defeats Persian. Ash wins a Lycanium Z and his third grand trial! (Source: Wikipedia)
