Ikkaku Madarame vs. Edrad Liones

Ikkaku Madarame vs. Edrad Liones is a fight that takes place on the streets of Karakura Town between 3rd Seat Ikkaku Madarame of the 11th Division and Edrad Liones. It is notable for being the first fight in which an Arrancar reveals what Resurrección is and what an Arrancar release looks like.

Prelude
When the 6th Espada, Grimmjow Jaegerjaquez leads an attack on the Human World, Ikkaku is seen with Yumichika ready for action to face the oncoming enemies. Ikkaku is left to fight one of his Fracción, Edrad Liones. Edrad makes the comment after Di Roy is defeated that whoever fought him was lucky as though he looked like an Arrancar he didn't deserve the rank. He was a complete failure. The Edrad then motions to Ikkaku and tells him that he has no luck at all as he has to fight him.

Fight
Ikkaku is attacked and goes flying through a nearby building. He then takes notice of a scared and confused Keigo Asano, who is wondering what is going on. He then asks Asano if he can stay with him, noting that if he takes care of the Arrancar it will save his life and therefore they would be helping each other out. After Asano says yes Ikkaku then asks the Arrancar what his name is, to which he is told Arrancar Trece but then Edrad stops himself stating that what would be the point of telling him anymore all that he needs to know is that he is the one who will tear him apart. Ikkaku is put off by this a tells the Arrancar about the concept of the "Last Curiosity". He tells Edrad his name and rank.

As the two fight Edrad tells him if that is all he can do with a Zanpakutō then it would better serve as a waist ornament as blades wont cut the Hierro of an Arrancar. Ikkaku attacks causing Edrad to move his own Zanpakutō to block the attack. Edrad tries to goad him stating that a Shinigami who refuses to release his Zanpakutō is a shame, but Ikkaku simply retorts that he is the one who needs to release. They continue to fight and Edrad is, however, easily overpowered by Ikkaku's unique style of fighting using both his Zanpakutō and sheath. Analyzing his fighting style, Edrad realizes the attacks of his blade come from his right hand, while the left defends using the Zapakutō's sheath, and he thinks he now has the upper hand. Unfortunately for him, Ikkaku is ambidextrous, causing Edrad to be left vulnerable as he switches the sheath and slashes Edrad's face, breaking the remains of his mask in two. Ikkaku tells him that he was lucky as he was going for his head. Ikkaku then spits out two teeth telling Edrad that channelling his reiatsu into his hands has lost him two molars but resigns to replacing them later. Ikkaku then explains that in 5 or 6 more attacks Edrad will need to release his Zanpakutō. Edrad plainly states that releasing or not won't make a bit of difference in the fight no matter who it is that does it first. Mocking Ikkaku for boasting of his own prowess when he should be cowering in fear at the opponent he will surely loose to. Edrad then takes out his Zanpakutō and releases (not knowing that Arrancar release their Zanpakutō in an entirely different manner to those of Shinigami). When Ikkaku asks him what is that Edrad explains that it is an Arrancar's Zanpakutō release as he transforms into a hulking form. He then finally announces himself as Arrancar Trece Edrad Liones.

Edrad then explains to Ikkaku what the true power of an Arrancar's release. He then sends a blast at Ikkaku sending him flying. Edrad quickly gains the upper hand as Edrad's Resurrección increases his reiatsu dramatically, allowing him to overwhelm Ikkaku with ease. As the fight is taken to the sky Ikkaku release his Shikai but Edrad suddenly appears and smash him into the ground and leaving a crater around him. As Ikkaku tries to get up, he is told by the Arrancar to give up gracefully, as there is no need for him to be beaten into nothing. Refusing to give up Edrad gives him a finishing blow causing a column of flame to extend into the sky. When the smoke clears Ikkaku has managed to withstand the blow holding Edrad's fist upon his back despite the fact that he is greatly wounded and Hōzukimaru is broken into two pieces.

When Edrad lifts up his fist Ikkaku explains that there was never a difference in their power. Realizing that since the others are in similar fights and won't notice, Ikkaku tells Edrad to be quiet, and promise not to tell anyone about what he is about to see, to which he then releases his Bankai. Edrad stands surprised at the release of reiatsu and that his opponent has Bankai. Ikkaku tells him that this is his Bankai, Ryūmon Hōzukimaru. Edrad makes a feint attempt at flattery but Ikkaku doesn't buy it and tells him that it is only natural that they both show their true levels of reiatsu. The two take to the sky and continue their fight with Edrad striking at Ikkaku with flaming fists. Ikkaku easily cuts through Volcanica right down the middle knuckles of Edrad's fist. Before the Arrancar notices too late that Ikkaku is about to attack him from above. When Edrad tries to block the blade cuts deeply into his forearm, causing Edrad to ignite his flames to push Ikkaku back. Edrad then notices that the Bankai's blade is damaged and cracked, resolving that he still has a fighting chance as long as his other arm doesn't get cut. Ikkaku then begins to swing around his Bankai, and when he sees that Edrad had realized that his reiatsu is rising, Ikkaku explains that Hōzukimaru is, in high contrast to himself, is a "lazy bum" and needs to be awoken, either through battle or by his current movements. Putting all of his strength into one final attack, Edrad does the same and both of the fighters collide in a large explosion. When the smoke clears, Ikkaku's Bankai breaks into different pieces and he falls face first into the ground below, followed by Edrad who has lost his left arm as well as the left side of his abdomen.

Afterwords
Afterwards, both Ikkaku and Yumichika go to Keigo Asano's home as a part of an earlier agreement for saving him from the Arrancar. Although Keigo, at first, tries to get them thrown out, hoping his sister, Mizuho Asano was against it, she only praises his actions and even gives Ikkaku and Yumichika both clothes and food. It is revealed that this is because Mizuho has a thing for guys with "shaved heads."
