Pokémon Season 5 Episode 50

Entei at Your Own Risk

As Ash and friends continue their travels with Larvitar, it remains wary of all other Pokémon and people, particularly of Misty. They stop briefly at a Hot Springs, and there meet a young trainer who reports that he is there searching for an Entei. Jessie and James disguise themselves as snow cone salespeople and trap Ash and friends, but using their Pokémon these trainers are quick to escape. Ash than challenges the Entei-seeking trainer to a battle in hopes of learning more about the secret attack that this trainer claims his Misdreavus will use to defeat Entei. This secret weapon turns out to be Mean Look, an attack that prevents one's opponent from leaving a battle. Moments after this battle, the enthusiastic young trainer runs off toward a sensor that is detecting the presence of Entei. Ash and friends follow, soon after witnessing a battle between this trainer and Entei. The battle doesn't go exactly as this trainer had planned, but leaves him nonetheless with a renewed respect for Entei.
