Challenge for Harry Potter Bleach Crossover. This is going to be slash between Harry and Gin or/and one of the Arrancars.
After Harry killed Voldemort once and for all the Ministry of Magic sentenced him to the Kiss for murder. His "friends" let it happen as soon, as they found out, that Harry had written a will and named them the sole benefactors in case of his death.
But dementors are in real a rare kind of Hollow. They suck the soul out of their victim. But instead of eating them they tune them into a full Hollow and send them to Hueco Mundo. What is left is the Empty body.
And because normal living can't see the Hallow no wizard ever realized they were actively crating soul eating monsters.
When Harry gained back his conscious thought he felt an overwhelming Emptiness. He had no recollection of his past but something in him screamed in pain by the betrayal he had suffered.
He swore to become stronger and to never again let anyone walk all over him. Mistrust was one of his strongest attributes and it would take a long time before he would deem anyone worthy of his trust.
Centuries passed by and Harry (new name please) grew stronger and stronger till he finally reached Arrancar level.
When Aizen started to collect his Army he naturally stumbled upon him and recruited him for his war.
Harry may have agreed, but he war wary of Aizen and didn't let himself be fooled. The reason he joined war more curiosity and a feeling in his guts than any need for revenge against the Soul Society.
And here is where I leave you full regain on the story (more or less).
My only demand is, that Harry is the bottom and that his name is changed when he becomes a Hollow.
Also Harry can have more than one partner at once but no more than three please.
Also pleas do not make him some godlike all powerful being or something like that. He is powerful without a doubt but he should not be all smashing and unbeatable.
I hope someone decides to write it.
If someone decides to write this I will ad another Chapter and tell you.
Ps: Sorry for any grammar or spelling mistakes I made.
