Zero Isle East (Japanese: ゼロのしま とうぶZero Isle East) is a dungeon in Pokémon Mystery Dungeon: Explorers of Time and Explorers of Darkness as well as Pokémon Mystery Dungeon: Explorers of Sky. It is one of the hardest dungeons in the game. Unlike Zero Isle North, the player can gain Experience points. However, the player must start at Level 1 (both moves and statistics) and can only bring 16 items with them (items beyond the 16th slot of the Treasure Bag will be lost upon entry). The player's level and stats will be restored once they leave the dungeon and will retain any items found within. In addition, if the player teaches a Pokémon a TM during the dungeon, it will be lost. Zero Isle East has a total of 40 floors and the Pokémon naturally found there cannot be recruited.
