Magical Pokemon Quest: The Helping Shadow of Friendship and Happiness

After the events of the AshVerse's "New Series" and the NanetteVerse's "The Theta Legend of Ice", Ash Ketchum and Nanette Daisy decide to think of what to do now that they fulfilled their destines. One night in a dream, however, they, a pony named Luster Dawn, and a girl from the KynaVerse named Nina Aarden meet each other (Ash meeting the latters for the first time) and someone that gives a mission for them and their friends to complete and save every-creature alike.

Note: I DO NOT own Pokemon, My Little Pony, or any of the characters used in the story. This is completely fan-fiction. The only ones I own are Nanette Daisy (a seemly-original character) and the counterparts of game characters. Also, credit goes to the deviant 'ky-nim' for the character Nina Aarden!
Note 2: I may need to change the cover, but I'll use this one for now.
Note 3: This is my version of "The Helping Shadow" by BonzY1337.
