Let's try this, all the women of Fairy Tail are in Mermaid Heel, Natsu, a courier, has a chance encounter with these Mermaids...I think we see where this is going. NatsuxHarem.

It has lived since the beginning. Since before the Dust settled on the world, bringing forth man. It has brought forth countless monsters to combat man and his creations in an attempt to annihilate him completely. But as the years pass, man becomes stronger and wiser, he becomes able to fend off its monsters. And now the creator comes to a realization. It needs an heir.

A sort of spin-off of "Eye of the Black Dragon". When Natsu devours the Etherion in the Tower of Heaven, instead of Dragon Force, he achieves a far greater power, one that he intends to use to the fullest extent. But he fails to realize, just who he may hurt in the process. NaLu

Instead of being raised by Igneel, Natsu is raised by Acnologia. How will the world take it, as the Chaos Dragon Slayer emerges. Could be called OOC, but maybe not entirely. First of the "Acnologia raises Natsu" stories, I checked. Cover by Konoha's Flash.

*Sequel to, "The Rising Dragon Champions."* After the Dragon King Festival in Crocas, Fairy Tail is back on top as the peak guild in Fiore! As everyone gets back into the swing of things, evil begins to rise as ancient demons stir and Zeref's dark power becomes ever more apparent. Amidst the chaos, a defeated outcast rises up, but he may just save those he once sought to kill...

An innocent mistake releases a horrifying beast in the bowls of Beacon, and no young Huntress's virtue is safe... [Tentacle Grimm/Every Female Character]

A thing I really wanted to do. Natsu is present when Fairy Tail disbands, and overwhelmed with hurt, and anger, he runs into the mountains. There, his despair consumes him, and something happens. What happens the next year, is something nobody in the now gone guild, could have ever dreamed in their wildest nightmares. Dark (but maybe not evil) Natsu.

AU/Timetravel, I created him for one purpose and one purpose only, and that was so that he could be my end, so that he could kill me and end my reign of terror. I made him into what he is, but he's grown into something far...darker than I could have ever imagined. I am not sure if I should feel proud or ashamed for he truly is, The END. Dark Powerful Natsu

History often hinges on a moment. What if young Lelouch avoided the fate of exile and remained with the royal family? All roles become reversed. The tale of Lelouch's quest for power and vengeance as the Black Prince of the Empire.

AU. Desperate and rushed, Minato Namikaze is forced to rely on the Death God's seal, a seal he doesn't fully understand, and his son pays the price with his life. So who is the blond-haired kid running around Konoha? M for language and violence.

AU: The motorcycle gangster gang called "Death-Dragon" have now in four years spread fear around the people in Japan. Luckily they're just around the area of Chiba. Their base, FTG, is the home for many youngsters, and one of those is someone we know. Rating M for Adult Themes, Cussing and Gore.

After the events at Crocus, Natsu still recovering from his injuries from the fight found himself dealing with his girlfriend Erza's naughty side, and gained himself two unexpected lovers along the way. This'll be a harem story with no real plot in it with Natsu and Erza as the main pair. Contains OOC and lemons.

What would happen if Natsu was raised by Igneel AND Acnologia. Trying to make this Natsu and Lisanna. Inspired by "Eye of the Black Dragon" written by Snakeboy33. Rated T just to be safe. Also don't make any racist jokes out of the title.
