Gabriel, the loving husband he was, was already eager to see this fight. Without Segunda Etapa—a transformation that only Gabriel, Starrk, and Harribel possessed—they were the only three Hollows who had reached such a stage.
Gabriel had unlocked his Resurrección naturally. His Segunda Etapa had come later, during his third year as King, when he devoured another Vasto Lorde who refused to submit.
Hueco Mundo could only have one king.
Anyway, through Barragan's memories, which he gained after devouring the former king's soul, he learned of a powerful Hollow.
The beast's name was Ikomikidomoe. From what he could gather, that Hollow had been the pinnacle of Hollow-kind for a while.
Deciding to invade Soul Society and getting royally fucked in the ass with no lube.
That mad scientist had also tried to invade Soul Society but was almost fucked raw by prime Yamamoto. Wow, Hollows really liked invading Soul Society and getting fucked in the ass.
Hmm... he wondered if he could try it. Unlike them, he had a whole army of powerful beings behind him. He wouldn't lose.
A vivid mental image formed in his mind of a giant, toad-like creature with elongated arms that nearly reached the ground.
Its forelimbs ended in large claws, while its legs were much shorter. The creature lacked a visible neck; instead, its head seamlessly extended from its body.
Its forehead was adorned with hexagonal markings, and a structure extended from its nose across its cheeks, ending in large circles located just beside the hexagonal patterns.
Additionally, a long beard flowed from beneath its small Hollow mask.
Hmm... a pet.
Somewhere else...
A Zanpakutō could be seen shaking... It felt as if its name was being disrespected.
He was the great ###...
Fuck you, Ichibe, you bald fuck.
The amount of slurs that would come out of this beast's mouth—he couldn't even say his own name, yet he could feel someone had uttered it.
His shape began to change slightly.
Somewhere deeper in the castle, the monk could be seen looking at a lifeless statue, then something felt odd. His control over names... something was interfering with it.
What could that be?
The Soul King's body seemed... to twitch.
The monk's eyes widened.
The Soul King was budging.
What could possibly cause such a thing?
The gates of Hell... were opening.
Meanwhile...
Gabriel could be seen all giddy, a smile on his face. He was like the most excited husband.
"You're letting your spiritual pressure leak," Starrk commented.
Gabriel tilted his head slightly at the remark.
"You're distorting the space. Hueco Mundo is shaking," Starrk added.
Gabriel's eyes widened.
Oh. Yeah. His bad.
Harribel, standing in the arena, sighed. Yep, that was Gabriel alright. To think he got this excited...
Ulquiorra said nothing. His Majesty seemed quite invested in this fight, probably paying close attention to it.
He shall not disappoint.
"DO NOT HOLD BACK. If I find out you did, I will personally transfigure your soul."
Those were Gabriel's orders. He didn't want people to think he was biased. (He was.)
He needed concrete evidence to advance Harribel to the next stage. And what better way to do that than to have her fight the strongest Sin?
Ulquiorra had never showcased his true power before now, so his full might was still unknown.
However, since his Majesty ordered it—and since he, in fact, did not want to die (being transfigured)—he complied.
He didn't know why, but something about Gabriel's power felt demonic, as if once you were hit by it, your soul was claimed by Hell, and there was nothing you could do about it.
And since his Majesty requested it...
"Segunda Etapa."
He completely skipped his Resurrección and went straight to his Segunda Etapa, his second release, one might say.
"Hunt, Tiburón."
And the Queen retaliated by simply releasing her Resurrección, not her Segunda Etapa.
It wouldn't be needed for this fight.
The clash of their Reiatsu caused the entire arena to shake. Even the nearby city trembled under the weight of their power.
Granted, the city wasn't that close—Gabriel had the foresight to place the arena at a distance so the regular civilians wouldn't become collateral damage.
The arena was quite a ways away, though a few Sonido could get you there in seconds. Still, it was safer that way.
A black pool formed behind Ulquiorra, the hopes and dreams of every weak Hollow watching the scene being consumed by his authority.
He was not going to lose this.
Ulquiorra Cifer would come out of this fight the victor.
"Here I come," he said in a calm voice.
Harribel gripped her blade.
She was ready for this.
Nothing the boy could do now would surprise her.
She was ready for anything he could throw at her.
After all, she was the Queen of Hueco Mundo.
Her Hierro was already at maximum.
Her skin was currently so tough that not even Nel's enhanced strikes (non-authority boosted) could harm her.
She could tank a few blows with no problem, she had the durability for that, and she could for the most part ignore his authority, now all that was left was to end this fight swiftly.
A/N Gabriel resurrection form is basically his vastolorde form.
