Kōga vs Vegeta

After a brief battle with the Arrancar turned Muramasa, he transformed once again into a huge and horrific dome-like structure that continues to grow, even engulfing Ichigo inside. His unstable energy opens a a huge Garganta, drawing in countless gillians and such. The others tried their best to stop them, but they were no match. Until...

Sode no Shirayuki: "Tsuginomai Hakuren!"

Sode no Shirayuki froze a menos in its place, saving Rukia and Orihime!

Rukia: "Sode no Shirayuki!? How are you here?!"

Sode no Shirayuki: "More importantly, you should know I didn't come alone."

Ikkaku: "Hey!"

Above them, all of the 13 Court Guard Squad Captains, Lieutenants and notable seated officers were there! And... with their zanpakuto by their sides.

Ikkaku: "You didn't think we'd let you have all the fun, did you?"

Thanks to Kurotsuchi, all of the zanpakuto defeated by someone other than their masters were restored and Muramasa's control broken. For those who had been retrieved by their masters, they were ready too to fight. Renji was one of the few that noticed Byakuya fighting Kōga.

Renji: "Captain!"

Byakuya wasn't doing so well against the stronger Kōga.

Soifon: "So that's Kōga, huh?"

Rukia: "You guys know?"

Ikkaku: "Yeah. Head-Captain Yamamoto and Captain Hitsugaya filled us all in. Makes sense now."

Toushiro and Yamamoto looked on at the amount of hollows of that were coming from the dome and the Garganta.

Hyorinmaru: "That's a lot of gillians."

Toushiro: "We can't afford to waste any time. Byakuya'll have to somehow deal with Kōga on his own. We must stop those hollows no matter what!"

Yamamoto: "Hitsugaya is right! All of you, focus your power on stopping these hollows at all costs!"

Everyone: "Yes sir!"

The zanpakuto were the first to attack the menos, intent on proving to the Soul Reapers where their loyalties lie. Most of the Soul Reapers soon joined in too. Toushiro stood back with Yamamoto for a moment, having grim thoughts about their strength.

Yamamoto: "What is on your mind, Hitsugaya?"

Toushiro: "I... I feel uneasy, sir. Ichigo is inside that dome with Muramasa. I have no doubt that he'll win that fight. But... I'm not so sure about us."

Yamamoto just stared at his successor.

Toushiro: "Kōga is much stronger than we anticipated, and the number of gillians and menos that keep appearing will quickly tire us out in no time."

Still, Yamamoto remained silent.

Toushiro: "We're out matched and out numbered."

Yamamoto: "Numbers do not win the battle, Hitsugaya."

Toushiro: "No..."

Toushiro just looked at the huge amount of gillians, two to three to every one of them.

Toushiro: (Still not very sure about the odds) "But I bet they help."

Yamamoto: "I feel your concern. But we must not lose faith. If we start doubting ourselves then we will have truly lost."

Toushiro: "I'm just saying I don't see us coming out of this in a good way if anything."

Yamamoto ended the conversation and ordered Toushiro to go aid the others. The young captain did so, despite knowing that they were in a hopeless situation. Menos continued to pour out of the Garganta in vast numbers while everyone did their best to hold back the enemy forces. Eventually, Byakuya fell to the ground. He was no match for Kōga.

Kōga: "You are pathetic. I expected more from the head of the Kuchiki Clan."

Kōga looked up at all of the other Soul Reapers, seeing their weakness with delight.

Kōga: "Only proves that I am the strongest Soul Reaper ever! No one can challenge me! Not a Zanpakuto, not a Soul Reaper, not anyone!"

Just when it seemed as though things couldn't get any worse... A rumble was felt on the ground. And then another. Everything halted and everything went silent, even the menos. The menos and gillians all felt it, and many began to retreat. It echoed through the wet foggy air effortlessly. The distinct sound of heavy footsteps against the earth. Just then... Levi came running out of the forest! He has been leading a very nasty X factor to places where he was needed. The soldier turned to the ancient Soul Reaper, the final opponent.

Kōga: "A human? Is this a joke?!"

Levi: "Oi! You want a challenge?!"

Kōga looked up, the heavy footsteps still approaching. And then...

Levi: (Nods to something in the forest) "Take him on!"

Vegeta suddenly broke through the foliage violently and shattered the silence with an angry roar! The ancient Soul Reaper realized what this was!

Kōga: "A saiyan?!"

Vegeta stepped forward and both he and Kōga sized each other up. Byakuya took the chance to make his escape. Pride and honor regardless, he knew better than to get in an angry Vegeta's way. The saiyan snarled.

Was this the one he's heard about?

Vegeta: (Slowly approaching at an angle) "Are you Muramasa?"

Being from an era where Soul Reapers actually, albeit vaguely, knew about saiyans, Kōga was surprisingly naïve to the danger that was in front of him. That was a mistake.

Kōga: "No. I am Kōga. Muramasa was my zanpakuto before I discarded him for his weakness. I don't need a worthless tool like a zanpakuto."

Vegeta: "You were his master?..."

Kōga began to get nervous. Vegeta was still approaching, even after learning his identity. In fact, even more intently than before. Vegeta then stood up on his legs and started making a quick beeline for the ancient Soul Reaper!

Kōga: "Are you stupid?! I told you! I'm not Muramasa!"

Vegeta: "JUST AS GOOD!"

The saiyan opened his mouth as he roared, poised his fangs, and... BATTLE ON! Vegeta sank his teeth into Kōga's arm so fast that the ancient Soul Reaper had no time to stop it! Many watched as Kōga struggled to pull the saiyan off of him. Kōga smacked Vegeta so hard that it forced the saiyan to release his grip. The ancient Soul Reaper then tried to impale the saiyan, but Vegeta bit the weapon in half with a bite that sounded like thunder! The two started throwing punches and everything at the other, but Kōga was soon outmatched. While Vegeta lay into Kōga with lethal ferocity, Levi prepped a smoke round. A short time later, he fired the round straight up into the sky! The smoke billowed like a beacon, signaling their location. And in a flash, Goku and the others all arrived with Eren and the others safely among them! The strongest of them wasted no time in eliminating the menos while Goku and Val used their energy to try and seal the Garganta! Down below, Vegeta had his teeth clenched around Kōga's neck and was throwing him around like a rag-doll! The great saiyan had the strength to end it right there, but he wanted to make it absolutely clear who was stronger! Above, the Soul Reapers all looked on as the Z-Fighters started doing what they could not, driving back the gillians. But they weren't just gonna sit there and watch. Toushiro and Hyorinmaru were one of the first to start gathering their Spirit Energy and unleash it. Ikkaku and Hōzukimaru followed suite with Renji and his zanpakuto joining soon after. One by one the Soul Reapers and Zanpakuto started unleashing their Spiritual Pressure to aid in driving back the forces within the Garganta! Goku and Val led the way as their power started to seal the Garganta with each passing second. Kōga tried to counter Vegeta, but he simply could not match the saiyan's power and ferocity! Claw like fingers sliced his skin like a hot knife through butter. With as much strength as he could muster, Byakuya also aided the others in sealing the Garganta with Senbonzakura by his side. Sensing that this was their best time, Goku powered up to Super Saiyan 2 and started pouring his energy into the Garganta! Toushiro and the others all soon followed Goku's lead and started pouring everything they had into pushing the gillians back and sealing the rift! The rift grew smaller and smaller with each second. Vegeta drove Kōga into the ground with just his tail. Finally...

The Garganta closed.

Everyone breathed a sigh of relief. But then, they all heard it clear as day. The sound of one final slice. Toushiro was the first to look down and see the scene over the foggy lake.

Vegeta has just dealt the finishing blow to Kōga.

The ancient Soul Reaper slowly started to fall.

Kōga: "How?... It can't be..."

Kōga used his broken weapon to prop himself up. Blood dripped relentlessly from Kōga's heavy wounds. He staggeringly glanced up, looking Vegeta right in the eye. The great saiyan just stared back at Kōga, cold black eyes filled with anger. The icy stare made the air chill all around the Soul Reaper. But Kōga still refused to accept defeat.

Kōga: "I won't... let them beat me!..."

He started to call out to his sword.

Kōga: "Come to me... Muramasa!..."

But his call was once again unheard.

Kōga: "... What's happening?... Answer me, Muramasa!..."

Vegeta did nothing but stare back, having already figured out the whole story while fighting Kōga. Kōga gasped for air as he stared back once again at Vegeta.

Kōga: "What... the hell... ... are you?!..."

Vegeta... only roared loudly at Kōga. That was his answer. Kōga tried one more time...

Kōga: "Mura... ... masa..."

Before falling into the lake. After a few moments, the bubbles stopped.

It was over.

Vegeta then just turned his gaze over to the huge dome that Ichigo was still inside of. A sudden explosion from it rocked the world! But once everything had settled, Ichigo was found alive and well on the small island on the lake... And with Muramasa as well.
