The sheer strength of Ichigo's resurrected form wasn't something that Aizen had anticipated. He thought the boy would be capable of mastering his hollow powers to the point of high speed regeneration, firing ceros and using the espada's sonido and hierro abilities. However, he never thought Ichigo would not only gain this level of power but also attain resurrection which only arrancar were capable of. Then it hit him, the only possible way that Ichigo would have attained a resurrection would be if his blade was hollow. A hollow zanpakuto, not an inner hollow, Zangetsu it's both his blade and his hollow and that fact scares Aizen slightly. The slight feeling of anxiety in the back of his mind, the unease beating of his heart is distracting to him but he can't help but feel excited for this battle. Despite knowing that he is immortal, he still feels the same anxiety and fear as a brand new academy graduate would feel facing down their first hollow. This however, isn't an ordinary hollow, this is one of his own design, one that he spent the better part of a hundred years preparing, planning and orchestrating the correct events in order to bring about the birth of this entity.
The traitor deflects an incoming blow from Ichigo's left sword before having to dodge to the same side in order to dodge the slash from the next. The ferocity of this monster he created is forcing him onto the back foot, while at first glance it would look like Ichigo had gone feral swinging viciously with both blades like a wild Gillian. Aizen notices that Ichigo's slashes all have technique, aim and precision. One blade strikes against Aizen's sword and the other is already mid swing preparing to cut at the opening that will be created behind Aizen's block. He had attempted to catch the black blade in his hand much like he did during their first battle, but Ichigo cut through the carapace, through his flesh and cut the top part of Aizen's left hand off before continuing into his shoulder, almost severing the arm in the process. Trying to regain the offensive, Aizen feints a slash towards Ichigo's chest before flash stepping behind him landing a solid kick on his spine sending him flying forwards towards a partially destroyed building.
Mid air, Ichigo flips to face Aizen before charging another cero between his horns, the black and red beam swirls inwards on itself before expanding and blasting out towards Aizen. The traitor captain raises a hand and casts it to the side casting a kido spell. "Bakudo number 81. Danku." Aizen declares, causing the invisible barrier to form in front of him and stop the cero dead in its tracks. The beam pushes past the barrier around its sides before detonating in the sky, blasting the clouds away. Ichigo stops himself from impacting the destroyed building but is forced to cross both blades in front of him in order to stop the incoming attack from Aizen. The force of the attack sends a shockwave that pulverizes the rubble beneath Ichigo as Aizen presses his blade against Ichigo's swords. The two can't read each other's facial expressions behind their masks but Aizen can tell Ichigo is scowling at him from behind the skull shaped helm of his resurrection. Aizen thrusts his blade downwards, breaking through Ichigo's guard and gashing him across the chest from his shoulder to his hip.
Breaking through Ichigo's grip caused Aizen to over swing, spinning forwards slightly as his blade cut through the left side of Ichigo's hip and shreds through his robes, spraying blood into the air. Ichigo howls in pain before turning a bit more animalistic giving in to his hollow slightly as he growls before headbutting Aizen with his horns stabbing into the traitor captain's shoulder blades. He gouges his blades upwards stabbing Aizen through the abdomen before leaning forwards driving his horns further into Aizen's shoulders then lunging off the air itself launching the two of them towards the ground. He slams Aizen head first into a fire hydrant and then into the concrete sidewalk completely obliterating it. Water sprays from the destroyed fire hydrant, tinged red with blood from both combatants before the ground explodes from another point blank getsuga from Ichigo. A massive crater is formed from this blast, causing several buildings around them to crumble from the explosion leaving nothing but dust and rubble.
