So basically Ichigo is the hollow king and he doesn't realize that until he meets Grimmjow and all of the espadas. All of the soul reapers even his closest friends (Rukia and Renji) try to keep the hollow king a myth by hidding it from ichigo. It's a boy x boy so if you don't like it don't read it. I hope you enjoy.

The Shinagami in Soul Society have cast Ichigo Kurosaki aside. He was forgotten by everyone. Everyone that is, except the Arrancar and Aizen, and they accepted him into their ranks as Espada number 0. Not like Yammy, who is Espada number 10 that can go to zero, no. Ichigo is much more powerful then that. He shares his massive room with Ulquiorra. Ulquiorra had a strange feeling, and neither he nor Ichigo understood it. What happens when he runs into some of the Shinagami? Will they try to take him back and use him or will he kill them all? I'm making this story because I think these two would be adorable together. I'm not too big on Orihime being shipped with Ulquiorra....

Aizen has lost the queen, but he has gained a rook, one for whom he has been waiting a long time: his Primero Espada, the creature that was once Kurosaki Ichigo. Story by: Saber Girls on Fanfiction.net

This takes place after the capture of aizen. Ichigo didn't lose his powers they just temporarily disappeared. After fighting Aizen ichigo passes out. When he wakes his friends have returned to the human world, he shortly returns but things were not how he left them ⚠️Grammatical errors ⚠️OOCness ⚠️ Foul language

In this universe, the Substitute Shinigami was betrayed by his friends and Soul Society who had decided to kill him because he represented a so-called threat. Aizen, meanwhile , being busy to create his army in the Hueco Mundo, what a surprise he had when he goes to meet with a vasto Lorde with familiar airs... GrimmIchi, if you do not like, do not read...

We all know how Ichigo lost his mother Masaki, who was a quincy, when he was very young. But what if he actually gets depression because of it? If his father started to neglect Ichigo thinking it's his fault and now only concerns himself with Yuzu and Karin? What if, during his fight against Aizen, Hollow and Shinigami/Vizards weren't the only ones there? When, still in Karakura Town, the Hogyoku that Aizen uses to become stronger reacts to the one with the strongest emotions. Wanting to fulfill wishes and helping him, it flies to Ichigo and brings EVERYONE into a certain, messy mindscape. Who and what will they find? Will they ever get out again? How will they react to the truth?... What happened with their war? Their plans? Slight Isshin!Bashing, sad!Ichigo, depressed!Ichigo, neutral!Quincy's, not_insane!Ywach, maybe OOC'ness.
