Genryūsai Shigekuni Yamamoto vs. Wonderweiss Margela

Genryūsai Shigekuni Yamamoto vs. Wonderweiss Margera is a battle that takes place in the Fake Karakura Town. It involves Genryūsai Shigekuni Yamamoto, the Captain-Commander of the Gotei 13, facing off against Wonderweiss Margera, the only modified Arrancar in existence.

Prologue
After a large majority of the Gotei 13 and Vizard are cut down by Sōsuke Aizen, a pillar of flame appears behind Aizen and Yamamoto emerges from it. Aizen tells him that his appearance is too late as he's the only captain of the Gotei 13 left with any actual offensive abilities. He continues to explain that if he falls, the entire Gotei 13 will collapse in on itself and he suggests to him that he should have come forth sooner. However, Yamamoto calls him arrogant for thinking he can actually cut him down, which causes Aizen to state that he thinks nothing of the sort, as he's already cut him down. Yamamoto tells him to be quiet but Aizen appears directly behind him. As Yamamoto turns around to confront him, Aizen stabs Yamamoto through the stomach. However, Yamamoto grabs his arm, claiming that he's now got him but Aizen asks him if he's really sure that this isn't an illusion. Yamamoto states that this would've been an issue if he were using his eyes to see or his skin to feel, but because he has now been stabbed with a Zanpakutō he could never misread the reiatsu from it. He then tells him that despite what Aizen may think, his opportunity to defeat him has never been greater and he reveals his Ennetsu Jigoku technique. Many pillars of flame surround them and Yamamoto states that everything that happened in this fight was gone into creating a chance to use this technique. Aizen tells him he's cunning for doing this while allowing his subordinates to get cut down, but Yamamoto states that he doesn't want to hear the word "cunning" from him. After telling him that the both of them are going to die in this burning hell, Yamamoto yells for Ichigo Kurosaki to fall back since he's not a member of the Gotei 13 and therefore he won't allow him to get involved in this. Aizen points out that if he continues this technique everyone else will get killed as well but Yamamoto tells him that they're prepared for that since dying to exterminate a great evil is the spirit of the Gotei 13. All of a sudden Wonderweiss appears behind Yamamoto in his Resurrección.

Battle
Yamamoto swings his Zanpakutō at Wonderweiss but he easily blocks it with his bare hand, which causes the flames to extinguish. As Yamamoto wonders why this happened, Aizen begins explaining to him that his Ryūjin Jakka is the most powerful Zanpakutō in existence and that if he were to fight it directly even he would have trouble. However, he tells him that if one were to abandon all other abilities and only specialize on one thing, then that person would be able to oppose its incredible power. Aizen states that Wonderweiss' Resurrección is called Extinguir and that he was created for the sole purpose of suppressing Ryūjin Jakka. He states that he got this power by giving up his language, knowledge, memory, and even reasoning. Aizen then tells Yamamoto that he's powerless before him and says farewell to the Captain-Commander. Wonderweiss then goes to attack his opponent.
