The official Japanese Pokémon site has just revealed the title for the 184th episode of Pocket Monsters Diamond & Pearl. With the premiere of the thirteenth Pokémon movie on July 10, the twelfth movie will air July 8. Because of this, the 184th episode, 「シンオウリーグ三回戦！シンジ対ジュン！！」 Shin'ō League Third Round! Shinji vs Jun!!, will instead air on July 15, making it the first episode to air after the movie.
While the previous episode will feature Satoshi's battle against Naoshi, as well as the beginning of the tournament on Suzuran Island, the recently-revealed episode will feature the battle between two of Satoshi's rivals, Shinji of Tobari City and Jun of Futaba Town, with Jun using his Emperte in the battle.
