The 185th episode of Pocket Monsters Diamond & Pearl, 「恐怖のトリックルーム！ サトシ対コウヘイ！！」 Trick Room of Terror! Satoshi VS Kōhei!!, will air on TV Tokyo on July 22.
The episode will feature Satoshi's battle against Kōhei, a Trainer he previously battled in a previous episode with his rival Shinji. He is known for his intelligence and his attraction towards Hikari. Trick Room is a move that can be learned mostly by Esper-type Pokémon, such as Yadoking and Dohtakun. However, it can also be learned by other Pokémon, like PorygonZ. It is, in the games, currently taught by the final Move Machine, and it allows slower Pokémon to move first in battle. It is one of several moves that have not yet been used in the anime.
