Starrk x Harribel(People Like Us by Kelly Clarkson)
In this universe what is different is treated as dangerous so it wasn't surprising that even after the shinigami won the Winter War they sent groups of shinigami to kill, or try to kill, the survivor arrancars even if none had wanted revenge for losing.
Some people, outside of the arrancars, weren't happy with this because it was nothing more than a repeat of what happened with the bounts and quincies but again it was a order of the so adored, but not, Central 46 that seemed to never learn from their errors.
Inside of the rest of the Las Noches the surviving arrancars started planning a revolution and little by little some more people joined them including some shinigami and Ichigo's friends/allies. The heads of the revolution were Tier Harribel and Coyote Starrk people who lived too much to see their comrades die because of the fear of some stupid old men. Yes they understood the reason for killing the hollows who appeared in the living world or Soul Society but they should leave the ones in Hueco Mundo alone.
Harribel knew enough how it was to be attacked just because she was different since rarely did female hollows survive a lot of time but her and her fraccion were some of those together with Nelliel and some other arrancar.
Starrk was always alone, well he had Lilynette after sometime but she was part of him for more than thousands years and now that he had people close to him he would fight to not lose them.
Both started this movement after a group of shinigami killed Tesla, the only fraccion of Nnoitra who died in his fight against Kenpachi, who was too weak to defend himself. They didn't lose time to contact Ichigo who in no time joined their revolution together with his friends/allies and some shinigami who didn't agree with Central 46 decisions.
People like them would only go down when the last of them was dead. They were different but that didn't mean the others had the right to decide if they should live or die even if they had to eat souls from time to time but again it was Central 46 that permitted everyone outside of Seireitei and some of the first districts live in the poverty which led to revolts and a lot of death.
Coyote Starrk and Tier Harribel would be known as the first couple that would become kings of Hueco Mundo and that thanks to them and their allies the three worlds lived in peace. Their kids would continue with their legacy and from them their story would be known to the world besides that it was written and marked in the history of all souls about the revolution that they started and led to peaceful times.
