Help, Tips, Suggestions, wanted.

[~Avant~]

Okay I am currently in the Pre-planning/Planning stages of writing a very large, crossover story containing 16 different anime/manga/cartoon/video game, universes. Now I've pretty much come up with most of the plot but I need some help in figuring out how to round it all off.

Here are the Universes that will be in this Fanfic:

1. Avatar: The Last Airbender
2. Bleach
3. Chrno Crusade
4. Claymore
5. D.Gray-Man
6. Devil May Cry
7. Final Fantasy 7
8. Full Metal Alchemist
9. Hunter X Hunter
10. Inuyasha
11. Katekyo Hitman Reborn!
12. Kingdom Hearts
13. Naruto
14. One Piece
15. Rave Master
16. Yu Yu Hakusho


Here are Some VERY important things that you have to keep in mind
NOTES:

1. For this story The Rave Master Universe and the One Piece Universe are one and the same. Just think of the Rave World as a part of the Grand Line the Straw Hats haven't Explored yet.

2. VERY IMPORTANT: The Inuyasha Universe, The Avatar Universe, and The Naruto Universe are also one and the Same. Baiscally the Fire Nation is under the belief that the Naruto Continent is full of Hidden Villages that are at was with themselves and so sees no threat in them. And they see Japan as a cursed Land full of Demons.

3. VERY IMPORTANT: This is the Anime Version of Full Metal Alchemist with a few elements from the Manga. So the Elrics are currently in Germany. Also keep in mind that Full Metal Alchemist, D.Gray-Man, and Chrno Crusade all take place in the same time period.

4. Time Periods:
1. Avatar the Last Airbender: After the first episode of book 3
2. Bleach: Just before Luppi and Grimmjows attack on Karakura
3. Chrno Crusade: None in particular
4. Claymore: After Time-Skip
5. D.Gray Man: After Noah's ark
6. Devil May Cry: After Part 3
7. Final Fantasy 7: After Dirge of Cerberus
8. Full Metal Alchemist: After the events in the movie.
9. Hunter X Hunter: During Chimera Ant Arc
10. Inuyasha: No particular time
11. Katekyo Hitman Reborn: 8 yeats after the varia arc
12. Kingdom Hearts: After Chain of Memories
13. Naruto: Post-Timeskip
14. One Piece: After Davy Back fight arc
15. Rave Master: After the Doryu arc
16. Yu Yu Hakusho: After the dark Tournament

Now with that Done I'll reveal The Story, for this fanfic(at least what I've got so far) If you want to read my story when I've got everything down, refrain from reading this Spoiler:

Namimori Town 8 years into the Future: The Vongola are in the middle of a big battle, thats being fought on the streets. They seemed to be overwhelmed and Tsuna is seen getting killed. However not everything is at seems for at the last moments while he's dying, Aion appears, and ask's Tsuna if he wants to be stronger, who accepts Aion's offer. And Aion Blasts the two of them with a modified Bazooka in the past to the 20th Century.

General Cross Marian finds Tsuna laying on the Streets battered and bruised. Cross asks for his name, but Tsuna can't remember it, or anything at all. So Cross gives him a new name, Giotto Vongola. Tsuna or Giotto, Meets Allen and the gang, who are then by attacked by a group of Akuma, Giotto uses his X-Gloves and fights the Akuma, thus making the group believe that he is in fact an Apostle so, Cross gives him a uniform, and Giotto Becomes an Exorcist.

Meanwhile in America the Magdelgne Order, gets info that Aion as well as his sinners, have begun moving to Japan. Thus Rosette, Chrno, and Remington, accompanied by Azmaria and Satella, go off to Japan to reindezvous with General Cross. Eventually they find out that the Earl and Aion are working together, and are searching for someone by the name of Edward Elric. And so a hunt for the Elric brothers begins.

Elsewhere, Kuroro Lucifer with his Genei Ryodan, and his newly reattained Nen powers, meets Xemnas and the Organization. Xemnas, tells Kuroro that he needs the Genei Ryodan to steal something for him so that he might use it to enter Kingdom Hearts.

Kurapica sencing his Nen Chain over Kuroro has finally been broken, begins to take action. Hisoka reveals that he has been following Kurapica for a while, in hopes of finding out when Kuroro's power would return. The two are interrupted, when Sora along with Donald and Goofy, appears questioning about the Organization XII. Kurapica believes the by Organization XII, Sora means the Genei Ryodan.

In being so many problems to deal with, Koenma reveals that he has hired a specialist, a Demon Slayer named: Dante Sparda. Yusuke and Hiei are to go to Karakura town to investigate the matters with the Arrancar and Shinigami. Kurama and Dante are spirited away to the place where the last movements of the Demon Lords where detected in a far off dimension, where they are to meet with a Spirit World Liason, named Sieg hart. And Kuwabara is given the task of following the powerful girl named: Kagome Higurashi.

Seeing the depth to their weakness, Aangs group feels hopeless, until that is that Gai insists he trains them. Gai begins to teach Sokka Taijutsu. And it is revealed that Toph is in fact a member of the Hyuuga Family, who has the Reverse Byakugan, which instead of allowing you to see everything like the Byakugan does, it blocks your eyes and heightens your other sences. Because Toph was never with the Hyuuga clan till this point, no one has been able to teach her how to turn off the Reverse Byakugan, and so Neji does, and so for the first time in her life Toph is capable of seeing.

Once preparation are complete the gang continues to Japan, Naruto and the others have been informed that the Akatsuki are headed in that direction, which more than likely means Sasuke will be headed their too. In Japan the Akatsuki meet and Battle Lord Sesshomaru.

Kuwabara follows Kagome into the Shrine and into the Well, after which he kills a few lowly demons.

Kurapica ponders as to why both Ubogin and Pakunoda are still alive, which Sora reveals that they had Nobody symbols on them.
