Hello and welcome to my bio where I'll post challenges or parts of them due to phone errors they disappear so I apologize before hand. Authors who want to do my stories please pm me I want to be notified and involved much as I can because I can't write at the moment but I'll help with ideas or plot as I'm terrible at fight scenes or emotional drama. I'm not the best at grammar and punctuation but fairly decent at spelling so I'll try to make it up to my fans.

First challenge: Blacked Fairy and the Gluttonous Fire Dragon of Sin.

Fairy Tail and Digimon crossover.

Pairings Natsu harem: girls and why:

Mavis Vermillion - having been raped by Zerf under the Contradictory curse then became the Fairy Heart made Natsu's life a nightmare but regrets it after seeing how far her revenge damaged the Guild and Natsu. Remorse, regret and guilt over having caused him so much damage to punish Zerf. Seven years of thinking, talk with Zerf, seeing how Fairy Tail acts, and Natsu having become exceptionally strong despite her and Fairy Tails efforts makes her realize her actions have done more damage than it should've been, and him becoming handsome. They have an antagonistic relationship that starts becoming friendlier after the Grand Magic Games.

Hisui - a deal made with Toma by Igneel for knowledge allowed them to bond as friends that spiral s into a crush after his exploits are known. She helps him get into Lamina scale and teaches him various society norms to better handle being a human as Igneel left holes in his teaching.

Chelia - main girl, mocked for having a childish body, her bubbly attitude and kind heart heals Natsu and teaches him how to utilize his God Slayer magic he obtains from Zancrow and Orga during his Seven Years of training.

only rare pairings allowed no Mira, Lucy, or Ezra but Brandish, Merudy, or the Age Snatch user I can't spell at the moment. Edolas counterparts are welcome including never seen ones like Mavis or Brandish ones.

A sharing issue must be answered by one or two love interests that set ground rules for the harem. No 100 girls 8 to 10 at best unless author is talented enough to do more successfully and there must be romantic development between Natsu and his girls.The magic and abilities:

He is the reincarnation of Beelzemon who killed the other deadly sins/ demon lords in opportunistic moments after a gencide war by the Royal Knights, 4 Sovereigns, Archangels, Olympians, and other Virus Buster groups and fleeing the dimension. His body was altered by his ability to convert his enemies essence into his own becoming pure flesh and blood from killing various enemies, humans, dragons, and demons alike while in Earthland. He weilds their abilities but at a much weaker level till he both increases in power and masters them. Beelzemon can steal the basics of any power when he absorbs an enemy he's killed this includes elemental powers and continuously increasing his energy reserves, muscle power, and obtain the name of the magic he gains by absorption of enemies. Due to the Sin of Gluttony along with the other Sins being passed to Natsu AND being on a Slayer Natsu can devour a magic to obtain its basics provided it's an element like sky or iron and not spatial or arc of time. Natsu can combine elements into modes if he devours a compatible element with the one he's using at that particular moment. By mastering the base magic of his modes he can use duel modes easier. Beelzemon agrees to become Natsu's new soul, his original one already went to its afterlife destination, and he despises senseless slaughtering. In exchange for training and mentoring Natsu at a later date on top of Beelzemon's body needing constant nourishment from killing living beings it's breaking down.
