'The Mysterious Visitors' is an LKHFF deviant art story written by crew member, kylgrv (the voice of Rafiki in the Fantasy Adventure movies.) This is the first LKHFF story written by kylgrv and it stars the characters from the adventure movies, but also characters that kylgrv created.
In New York City, four people from an unknown universe appear and explore the city. The Fantasy Adventure team gets curious about them and introduce themselves. The new folk reveal themselves to be Kyle Otter, Roy Prong, Twilight Sparkle and Wubbzy, members of Future Time Travel (the FT Squad.) They become friends, but they must deal with Heath Lynx, who is, again, on a mission to win Rae's heart. However, there's another enemy who's teamed up with Heath, and he's not after love, he's after revenge against Kyle. Will the team manage to defeat Heath and his new foe, or will Heath and his new partner dominate over the LKHFF?
