With the plan formed, it was essentially the same as it was originally in the OG movies where Ghidorah was sealed in the Antarctic, however instead Kon was going to be the spearhead of the fight with both Godzilla and Mothra being the support since Ghidorah has been strengthened, although they don't know how yet.
As they were nearing the end of the finer details, they had also allowed leeway with it since they didn't know everything. Kon did give a lot of information about the abilities of what OG Ghidorah could do, but it'll be enough for what they are aiming for.
They started making their way up to find Ghidorah. Kon made a portal to the Nepal mountains. They planed on taking on Ghidorah where it would be beneficial to Godzilla in particular. Since the other three are okay for movement, they are trying to force Ghidorah to come in from fewer directions to attack from, so the mountains were perfect, being both numerous enough and close enough to cause aerial fighting more difficult for Ghidorah.
Mothra will stay near Godzilla since they are much like Kon and Junko, they compliment each other.
While they set a little bit aways, they wait. They wait for quite some time before they feel the ground shake. Kon knows it's Ghidorah, it's the same feeling when he saw the behemoth stare him down when it first landed.
However, contrary to what they expect, they feel the shaking stop. All of them are confused until the gravity beams come through the mountains in front of them. Kon barely has time to dodge it and thankfully Junko was already floating so she went up over the beams themselves. Godzilla sent an Atomic Breath back towards where the beams came from in hopes of hitting the alien.
Although all that achieved was two more gravity beams coming through the mountains to hit him. This caused him to fall over from the impact. Mothra takes this chance to start flying the mountains to try and surprise Monster Zero from the rear like they planned. Staying low so that she didn't get seen from flying above the mountains.
Kon and Junko go around and start sending magic spells towards the monstrosity, which had finally come through the mountain in front of them. The gold body with purple lines running all around it crashing through what was left of the rock. It immediately locked onto Kon and started charging its gravity beams again, planning to unleash them all. However, Mothra came from behind and started spitting the silk. What they didn't expect was the heads to dodge, not having to turn around to dodge. Kon was visibly more wary, along with the others.
That didn't matter though as one of the heads turned faster than it should have and a gravity beam hit Mothra dead center. Being launched backwards into a mountain.
"What!" Kon yelled, Junko realizing that this is worse than what even Kon thought.
Ghidorah, in front of Kon from a distance, finally had all its heads turned towards Kon. "You have been a pain for my benefactors. They had plans for the worlds you been to previously, the Kaiju's were supposed to corrupt the Earth, turning it into a wasteland only the strongest could survive in. And in that Dungeon world, you didn't even let the plan start, taking away what was most essential."
Kon listening to the one, or ones, in front of him was visibly concerned. With this new information, it opens up his eyes more as to his situation, but he can't let that unnerve him right now. Not while the one in front of him is still left to do whatever it wants. Junko however, looks at Kon in concern, taking her eyes off the monster for a moment. Ghidorah however, doesn't attack Junko in this moment as it realizes that Kon is the biggest threat, although it doesn't know why.
"My masters have given me a few boons as to what will help me in my mission to dispose of you. However they couldn't do much since the Laws wouldn't allow me to be changed too much. But so far they seem to be effective."
"Oh, and what would that be? Do tell since you seem to be different from what you were supposed to be." Kon asked. Not caring if they are someone who took over that body or not doesn't matter, what matters more is what they have changed about themselves.
"Oh, since you seem to be so interested, I won't tell. It'll take the fun away from finding out for yourself won't it?" Monster Zero said while chuckling, the three different heads causing a distorted symphony of notes that should have never been made.
'Alright Kon, so far he's shown to be faster than he should be, most likely to avoid anything that I can send at them....it.....whatever. Also showing that they have better situational awareness around them, also seeming to deal with surprises.....Looks like the ganging up won't be helpful from Mothra or Godzilla unless I can keep it still for them to hit it. Junko can move around and take pot shots but doesn't have the umph unless she charges it, to which she'll be focusing on dodging and charging at the same time. This doesn't look good, but at least I can still do something. I haven't tried moving faster than what the others could react to, guess I need to flex a little bit.' Kon thinking at high speeds, trying to figure out a way around the obstacles lined up on sealing them.
Kon uses a magic spell that Junko had shown him before when they were exploring their home, allowing him to talk to her telepathically. With this it allowed him to keep his eyes on Monster Zero as he also got ready to move. With the slight movement, it caused Monster Zero to focus on Kon since it still didn't know everything of what Kon could do, and was more wary of him than the others.
"I want you to focus on the sealing magic. I'll keep him distracted so that you can focus, however, that means that it'll most likely also try to target you. It has a sort of 6th sense that allows it to perceive threats and surroundings better than what the original is supposed to be able to do. Just make sure not to miss, else we won't get a second time, I still have the sound cannons, but I don't want to use it. I might hit you or the others."
Junko just nodded, the movement caused the eyes of one of the side heads to notice, and telepathically tell the others.
Kon, taking the moment to ready himself, used his FTL speed to move around to the side of Monster Zero and pouring magic into his tails, spears it multiple times before pulling back a distance. Ghidorah not expecting that was in surprise, allowing Kon to get the hits off. What was interesting though, was the fact that Ghidorah's healing was still the same as it was in the movies so far. Causing it to scream in the sudden pain, it turned towards where Kon stopped and launched its gravity beams again, and this time, taking to the air, trying to make some distance between it and Kon.
Kon smirking at the monster, Ghidorah was confused before it's 6th sense went off the charts to dodge at all costs. Kon had made his magic construct sound cannon, taking the chance to fire while there was no collateral damage worry while the thing was in the air. Only taking the few moments, Monster Zero had backed up greatly, proving that what Kon thought about it being faster true.
Kon, focusing on not missing, wasn't going to risk it to say some catchy line. Aiming and then firing in mere seconds, it struck Monster Zero, however Ghidorah had moved his body last second and instead of being hit center mass, it caused the cannon to hit it's wing, tearing it off along with some of its body. Plummeting to the ground, it hits the tip of one of the surrounding mountains and tumbles down.
Kon looks around, and seeing Mothra and Godzilla to his side after finally getting up from the gravity beams. 'Looks like his abilities have been improved. But if his speed, power and senses have been improved, why isn't his healing also improved?' Kon thinking to himself. Turning back to look at where Ghidorah had landed, he was only greeted with the sight of three gravity beams hitting him. Being launched backwards into the mountain behind him, it winded him. Junko seeing him getting hit, stops her spell.
"Kon!" Junko flies down as fast as she could from her hiding spot in the mountain side. Kon, getting up as quickly as he could. "Kon, are you okay?!"
Kon just nods, still winded slightly. Although there was no real damage, it felt like Kon had been hit again by the thing that sent him to the afterlife. "I'm fine, just catching my breath." And while he's getting up, Monster Zero also does the same, healing at the same rate again as the OG Ghidorah.
'Why, why does it seem like he's holding back, I haven't been able to understand why all it's other natural abilities have been buffed other than it's healing.' "Junko, be extremally careful right now, I have a feeling that something's not right. It's holding back." Kon said out loud. Junko, wide eyed stared at the Golden Demise in front of them.
"Oh, so you noticed?" Ghidorah said. Overhearing what they were talking about. "How did you notice? I thought I had played it well off, so I wonder what gave it away."
"Your healing." Kon said. Ghidorah's heads had their eyes narrow slightly. "All your natural abilities have been enhanced, so why is your healing been the only thing not been enhanced?" Ghidorah hearing the explanation, was extremally amused. It didn't think that it would be exposed like it was, but it was still within reason as to what it could do kill Kon.
"Well then, this makes things easier for me. Now that I can't hide it anymore, why don't we take things up a notch." And with that, the wing and parts of the body that Kon had destroyed with his sound cannon almost immediately heal.
"That's not all, if that's what you're thinking." Monster Zero, fanning his wings and becoming as big as he could, which was already at 350ft tall, gets even bigger. With the purple vein like lines going across its body becoming even more grotesque, causing the mostly golden body to become half gold have purple, looking more and more corrupted than when it first landed. By the time the transformation ended, it was at the same height that it was in the movie when the OG Godzilla and Ghidorah fought, at around 520ft tall. Dwarfing Kon and the others easily, it looks down at Kon with its face already showing that it won.
