Danny Phantom/Gravity Falls crossover Completed The Fentons are going on a month-long trip to Gravity Falls to visit family. But when Danny clashes with his second cousin, he begins to spend time with some of the town's other visitors: Dipper and Mabel Pines. Only problem is, the Mystery Twins can sense that something is off about their new friend. As Danny scrambles to keep his phantom half hidden, he wonders whether he should avoid the Pines altogether. The reclusive Grunkle Ford is on to him, and Dipper has become obsessed with researching ghosts. There's no way that the halfa's secret can stay that way for long. Yet the residents of the Mystery Shack aren't the only ones looking for Danny's alter ego. Powerful forces have combined to take over three dimensions, and the Ghost Boy is the key to their success. Danny doesn't know who to trust. Dipper needs to prove himself. And Mabel wants to keep her brother safe. Takes place before Phantom Planet for Danny and a couple weeks after Ford comes back for the twins. PG-13 Not rated for cursing, but for suspenseful/possible scary scenes. I don't own Danny Phantom or Gravity Falls (duh!), and I won't be adding any extra characters (except maybe a monster or two). Enjoy! Praise for Phantom Falls: "Yay! This is the perfect crossover. You're really nailing the personalities. :)" - Chilazilla "By far one of the better GF/DP fanfictions I have read in a long time. Characters are well-written, grammatical errors are near destitute, and the story flows together easily. I love it!" - taykatherine "You're totally acing Ford['s character] here and I love it so much." - venice-da-mink "This book is freaking awesome! XD" -RadioGlitch

(A/N: PLEASE NOTE, THE SECRET TRIO IS A FAN BASED TEAM FROM THE SHOWS DANNY PHANTOM, RANDY CUNNINGHAM: 9th GRADE NINJA, AND AMERICAN DRAGON JAKE LONG. THESE SHOWS BELONG TO THEIR CREATERS, THIS IS JUST A FAN FIC!!! BTW: the cover didn't belong to me, all art in this book belongs to their rightful owner) Danny is confused. He hasn't battled any ghosts for the past 4 weeks. Something up, and he's going to find out what. Randy is kinda angry. The NinjaNomacon has been saying the same thing for the past week. What dose it mean? And who are these people teaming up with The Sorcerer? Whoever they are, they must be bad Jake is happy. No magical world problems for the past week, but what is with all these ghosts?

In a world of magic, legends, pirates, and mythical beings, Fiore is a kingdom long forgotten. Within the deep blue of its ocean, the Obsidian, lies a lone mermaid by the name of Lucy Heartfilia. She has run from home, a home overrun by her corrupt father, and now roams the seas with her best friend Plue, a shapeshifter in the form of a white dolphin. One day, she dares the forbidden, and climbs to land. There, she possesses the legs of a mortal, and can roam as something she is fated to never be. However, when Trackers kidnap Lucy and try to sell her for her magical abilities, she manages an escape and is now on the run from the Trackers, being put under a spell that no longer allows her tail to reappear until nightfall. Stuck in a foreign place with Landwalkers, she must return home to have the curse lifted by her father, but she needs help to do it. However, she didn't expect a pink-haired sea captain to be it. Natsu Dragneel is the captain of his beautiful Fairy Tail, but he searches for something most valuable: the pink Obsidian stone, a rare and valuable treasure that could pay millions of jewels. But the pink-haired adventurer isn't in it for the money; no, that is a simple bonus. Natsu is in it for its wishful properties, able to grant a one and only wish to whoever takes it from the bearer. The only problem: he has no idea what it looks like, or where to find it. All he knows is that he needs it desperately. But, a beautiful maiden with the wish to return to her home in the middle of the Obsidian Sea, with Trackers after her thirsty for blood...that might be a good place to start. With an adventure full of sirens, fairies, cats and mages, the Captain and his Mermaid may just be caught by their enemies...while falling in love in the process.

Prior to the rewrite, the story will first take place when Valka and Hiccup were captured, and Stoick picking himself up. For now it's their adventures we'll look into before Hiccup takes the wheel.

Pib, an Irken Invader, is sent to a planet for Impending Doom 2, but something goes horribly wrong.
