With Aizen giving his consent for them to let loose as they please the whole area got suffocated from the bursts in their Reiatsu...
Nakeem Grindina, Edrad Liones who were fighting Hitsugaya and Ikkaku with the former keeping him at bay while the latter caused the first pillar to break drew their swords and they weren't the only ones...
Edrad: "Erupt!!! Volcanica - Volcanic Beast!!"
His Zanpakuto looked like a regular katana, but with a hexagonal-shaped guard and a slightly-longer hilt.
When he activated his release command an explosion of heat burst up as his mask reformed into wings on either side of his face and his arms morphed to gigantic proportions while growing large extensions beyond his shoulders.
Each of these extensions contains an exhaust spout that releases flames when Edrad is charging up an attack.
Nakeem: "Return!!!"
The moment Nakeem uttered a single word his Zanpakuto which was a katana with a yellow hilt and a circle guard glowed before it burst apart in a yellow reiatsu.
His mask started growing covering his full face and then a black mass was expelled from the inner sides of it as it was slowly engulfing his whole body, this caused him to take the appearance of a somewhat Menos...
Similarly the others, Luppi, Grimmjow also took it to the next level...
Luppi: "Strangle!!! Trepadora - Climbing Vine"
When sealed, his Zanpakuto resembled a kodachi with a four-pronged silver tsuba, pink sheath and matching coloured hilt.
He wore his Zanpakuto on his left side, just under his arm, in a little compartment within his shirt before he released it...
The Reiatsu cloud that was huge in front of Matsumoto died down revealing Luppi having gained eight enormous tentacles, each of which is connected at one of the corners of an octagonal design fixated on his back, and a bone cowl on his head.
Grimmjow: "Grind!! Pantera - Panther King"
Grimmjow was looking at the calm Ukitake who was facing him with his sword before Grimmjow held it up, giving it a low sweep stroke, with his right hand.
The sword glowed light blue as he puts his left hand up to it. He then rakes his hand along the length of the blade with a swift motion, while calling out its release command, which in turn releases a torrent of spiritual power that creates tremendous gusts of wind in the immediate vicinity.
Everyone was shocked by the sheer amount of power and crackling in the vicinity causing Ukitaka to tense up and he wasn't the only one...
Grimmjow's appearance changed drastically to something more feline and predatory. His teeth become jagged and sharp, his hands turn into black claws and his feet become black clawed paws, similar to that of a cat, along with a slender whip-like tail that's longer than his body.
His hair becomes very long and flowing, and the markings around his eyes enlarge and extend to the tips of his ears, which become swept back and cat-like.
He loses his distinctive jaw mask, which is replaced by a sort of a headgear upon his brow covering his forehead.
His clothing changes to become form-fitting white segmented armour, he continued looking at Ukitake before he raised his elbow upwards...
Ukitake noticed that the way his elbow was placed it was like he was targeting someone and then looked confused...
Grimmjow: "Garra de la Pantera - Claw of the Panther"
Acutely shaped bombs fired at high speed from his elbow, and when Ukitake saw them he counted five heading towards a certain overgrown person...
On the other side just as two figures were about to clash, more specifically a giant phantom sword and a giant arm...
The owner on that arm suddenly screamed as he now hand was crippled while a few dark green, crystalline, things were nailed on his flesh...
