When Percy Jacksons mom and step-dad are killed, he gets adopted by the Fentons, since after all, they were great friends with his mother. However that may be, Percy struggles to keep his secret from the ghost-hunting family, since he was half God. Little did he know, someone was also struggling to keep his secret as well. Danny thought having to keep his secrets from his parents was bad enough, but when they adopt a 17 year old boy, he knows the struggle is about to get real. Having to fight ghost, and keep your secret from a curious teen who was 3 years older, is more difficult than he though, when the ghosts get more rambunctious. A/N I do not own PJO, HOO, and Danny Phantom, they belong to their rightful owners. I am making Percy 17, and Danny 14, but instead of being somebody really vicious and killing off the 7 AND Percy's family, I'm just killing off Percy's family. I'm not a fan of the 7 dieing, after all, I love to use Leo to make a story.... 'special' I haven't seen any fanfic like this, so I thought, 'Why not?' I mean I've seen PJO and DP crossovers, but none had Percy adopted by the Fentons, and it's something I wanted to read, so I though, 'Why not give it a try.' I'm still waiting for my ideas to crash and burn.

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

UNFINISHED [NOT CURRENTLY BEING UPDATED] Danny Phantom/Gravity Falls/ Young Justice crossover Sequel to Phantom Falls (read that one first) When Danny finally left Gravity Falls, he thought that his troubles with shapeshifters, monsters and demons were over. He was wrong. School is about to start, and the halfa hasn't been able to forget the things that happened in Oregon. Neither can the Pines twins, who are going back to California in only two weeks. Mabel especially is not feeling like herself, and Dipper hates to see her this way. They're on the road to recovery. That is, until a certain group of costume-clad teenagers decide that they're going to take down a public menace: Danny Phantom. With no orders from the League, Young Justice kidnaps Danny, unaware that their ghostly enemy is part human. Getting their best friend back is not going to be easy, as Sam and Tucker soon learn. They, Jazz, and the Pines' group are willing to do anything to bring Danny home, even if it means breaking into superhero headquarters. PG-13 Not rated for language, but for suspenseful/scary or emotional scenes. I do not own Gravity Falls, Danny Phantom, or Young Justice, as you have probably guessed by now. No major OCs, except maybe a monster or side character needed for the plot. Takes place after Phantom Falls, and after season one of YJ. Not currently being updated. Enjoy.
