(Japanese: えんまくの中のバトル Battle in the Smokescreen) is the sixteenth chapter of the Pokémon Gotta Catch 'Em All manga.
The chapter begins with Shu and Pikachu battling a group of Zubat in a cave. After Shu manages to capture one, he hears a mysterious voice calling out to him by name from deep within the cave. It turns out to be somebody riding a Dragonite. Shu approaches the mysterious person, who continues to taunt him. He reveals his name to be Ken, and Shu challenges him to a battle.
Ken sends out a Koffing and commands it to use SmokeScreen, completely blocking Shu's view. As Shu is trying to plan his next move, the ground starts rumbling. At the same time, something unseen starts flying around and hitting Shu and Pikachu. Ken reveals that behind the smokescreen, he has Shu surrounded by Pokémon - Pidgeotto from above, Cubone on the sides, and Dugtrio underground. Realizing that he needs to get rid of the fog created by Koffing's SmokeScreen before he will be able to fight back, Shu sends out his newly caught Zubat. Since Zubat can use echolocation to navigate even in the dark, it is able to pinpoint the location of Koffing. Now knowing where to strike, Shu commands Pikachu to use Thunder, defeating Koffing.
The fog disappears, and Shu is nowhere to be found. He appears on top of Ponyta, who has jumped high above Ken's head. Shu commands Pikachu to use Thunderbolt, defeating the rest of Ken's Pokémon. As a prize for winning, Ken gives Shu a signed guitar, which he considers extremely valuable. As Ken walks away, Shu comments to Pikachu that the guitar is completely useless to him.
