#pocketmonsters has just revealed the 165th episode of Pocket Monsters Diamond & Pearl. The episode 「四天王オーバとジムリーダー・デンジ！」 Elite Four Ōba and Gym Leader Denzi! is set to air on Feb. 25 on TV Tokyo.
After almost forty episodes since Satoshi obtained the Glacier Badge from Suzuna, Nagisa City's Gym Leader will finally make his appearance in the anime. According to Kurotsugu, Satoshi will be able to give Denzi "a shock," which may be a hint that Denzi will be similar to how he is in the games Pokémon Diamond, Pearl and Platinum. His friend Ōba, a member of the Four Heavenly Kings and a Trainer of Fire-type Pokémon, will also appear in the episode.
