The main difference between Pokemon Explorers of the Sky and Pokemon Explorers of Time is that Explorers of the Sky is an enhanced version of Explorers of Time. Explorers of the Sky includes additional features such as new storylines, characters, dungeons, and Pokemon compared to Explorers of Time.
