Lysandre has returned with a plot to end Equestria, and the Mane 6 are powerless against him, but according to every single Pokemon game one thing will alway work. Sending little kids with Pokemon to stop them, and three fillies fit the bill. Along with the help of Quilava, Ash, and his friends they might be able to pull it off, but in order to do that the CMC will need to catch Pokemon of their own.
