At the Castle Bravo base in the Tartaros sector, everyone was holding their breath at the success of the titans in saving the world once again. Hopes also rested on young vigilante Kim Possible, still in a deep trance, sitting in the control seat of the new mechagodzilla, Kiryu, made from a fusion of steel with the scales and skeleton of a titan long dead, Zilla. However, the link created between the human mind and the machine, similar to that of the Jaegers, required a constant and demanding effort from Kim and despite her strong and determined spirit, she sometimes showed grimaces of fatigue, which worried her parents. Ron and Serizawa. Shego, being his natural enemy, however, also showed some signs of concern, not ignoring to what extent the success of Kim and the titans was a question of survival for this world.

Ron, his arm in a cast, stayed by Kim's side at all times and holding her hand for moral support was all he could do now. He believed in his girlfriend, giving up was an unknown word for her. Thanks to Monarch drones sent there and equipped with high-tech cameras, Serizawa and the others could follow the progress of the battle via the holoscreens. Kong, Rodan and Behemoth appeared to be out of action but alive. Godzilla was injured, with Elsa and Mothra supporting him. Kiryu and Gamera were now facing Gigan.

_"How much battery life does Kiryu have left?" Henri Serizawa asked the team of scientists.

_"Five minutes." one of the men replied, looking at his screen.

_"It's not much, but let's make it worth it!" Serizawa added, choosing to believe it.

_"Serizawa... If anything ever happens to my daughter... I will never forgive you." Ann then said frankly.

_"I know... And you will be absolutely right." was all the Monarch director said.

*************

In the Void dimension, a Dantesque and decisive battle had just begun between Chernabog and Maui, the two entities moving at supernatural speed through the air, their weapons clashing against each other with brutality without any don't take the advantage. The expressions in their eyes expressed better than any words. Only one would emerge alive from this confrontation. Knocked to the ground by a blow, Maui quickly regained his senses and retaliated with a massive shoulder strike against his enemy who was knocked back. Chernabog, furious, summoned a shower of sharp black energy projectiles at Maui who changed into a hawk to avoid them with spectacular aerial acrobatics mixed with his speed.

Meanwhile, the vortex leading to the underworld continued to swallow everything around it over a large radius. Anna and Moana, their weapons in hand, continued to protect Jia against the attacks of Chernabog's shadow demons who continued to arrive. While decapitating a demon with her flame sword, Anna noticed something in horror as she looked up, seeing several increasingly wide cracks being created in the sky.

_"Oh no! The boundaries of dimensions are breaking! If we don't close the vortex, all of reality will shatter into pieces!" warned the fire fairy.

Moana was also horrified by this vision. In his vengeful madness by opening this vortex to hell, Chernabog had broken one of the primordial laws that governed the reality of this universe: never open a passage between two dimensions. The only way to stop this now was to close the anomaly. Huddled against Moana, Jia contemplated with distress and helplessness the end of reality which was beginning before her eyes. Anna resumed the fight against the demonic shadows while Moana gently took Jia by the shoulders, looking into her eyes.

_"Jia, you need to concentrate and master your power."

_*I can't do it! I'm too afraid! I don't know what to do!* signed Jia in tears.

Moana understood very well, not judging her. A soul so young should not carry such a burden. It reminded her of the time in her lifetime, when she was chosen by the ocean to bring back Te Fiti's heart, and later, becoming Kong's chosen one. Gently, she placed her forehead against Jia's.

_"I know it, little sister." she said tenderly. "I too was once afraid, like you. Fear of not being strong enough, fear of not knowing how to do what would be right or not. Fear is natural, just like this other feeling that I chose to guide me: hope. The hope of one day seeing again the ones I love. I know life hasn't been kind to you, but you're not alone anymore, Jia. You have a family who loves you and believes in you, but most importantly, your own faith in yourself. Make it a strength and embrace your destiny, as I did."

Jia closed her eyes, focusing all her thoughts and every bit of her being on those she loves. The Possible Family. Kong. Elsa and Godzilla. Moana. They wouldn't want to see her give up. Jia then understood... It was fear that prevented him from acting, the fear that Chernabog engendered in the hearts of mortals with his demonic aura. This cursed demon had caused so much suffering, so much terror, so many lives had been destroyed because of him... Jia would not allow him to touch those she loved!

Not far away, Anna summoned a wave of fiery flames with her sword to sweep away and char a group of shadow demons. Suddenly, a very intense and brief feeling tickled her fairy mind, causing her to look up. From one of the cracks in the sky, a thing, almost like a misty and glowing shooting star, escaped with superhuman speed and immediately disappeared into the water on the ground. A first soul had just escaped from the spirit world, and if nothing was done, others would come. By being able to observe him for a second before his disappearance, Anna was able to feel the very special aura that emanated from this soul and this brought back memories in her that were both happy and sad...

_"Z...Zilla..." was the only word she could say.

************

In the ruins of New York, Gigan was the first to attack, firing a volley of lasers from one of the cannons. Kiryu blocked the shot with his wrist blade and fired a rocket from his other wrist which hit the alien cyborg in the chest with a violent explosion. Gamera added a powerful breath of flames completely covering Gigan. But it emerges from the flames with a powerful leap and a shrill metallic roar. Propelled by the force of his momentum, Gigan spun his blades around, becoming a deadly giant spinning top that struck Gamera and Kiryu head-on, knocking them both to the ground.

Kiryu quickly got up and a duel began between the two giant machines, their blades clashing against each other. But Kiryu fought back, covering one of the fists with intense electrical energy and delivered a masterful punch to Gigan's face. Kiryu continued his momentum and delivered more punches and blade blows to Gigan, but the latter responded with a tail swipe that threw Kiryu back. Gigan flew into the air and Kiryu and Gamera chased after him, flying away as well. Seeing that the fight would continue in the air, Elsa signaled Mothra to go help them while she stayed with Godzilla and the other titans to support them. Mothra nodded and flew towards the fight. Godzilla looked towards Mothra, wishing her luck with a growl and turned his gaze towards the ice dragon, the titan form that Elsa had taken. He knew it was her, but yet, his age-old instinct told him something... Elsa had changed, but there was also another presence having merged with his queen, very slight but very real and familiar that he recognized. ... A long lost love... Sisu... Godzilla seemed confused, emitting a soft growl as he looked into Elsa's eyes.

_"Don't be tormented anymore... I'm here, my love." then said the voices of Elsa and Sisu in unison, becoming one.

Gamera, while flying, spat out several huge fireballs while Kiryu fired a volley of homing missiles from his shoulder cannons. Gigan, with his extraordinary speed and agility despite his size, dodged all the projectiles in aerial acrobatics and responded with a powerful and precise laser shot that hit Kiryu head-on, causing him to fall from the sky and crash into a remains of building. Gamera charged, tucking his head and paws into his shell. Using the holes in his shell to propel flames, Gamera spun around faster and faster and with his speed collided with Gigan who was destabilized. Mothra appeared in turn with a majestic roar, spreading her wings and summoning a cloud of burning beams of light which rained down on Gigan and touched him in several places, also causing him to fall from the air and fall violently to the ground.

Gigan quickly got up, and seeing that Mothra was rushing towards him, pulled one of his chains which, like a whip, wrapped itself around the Queen of the Monsters. Gigan used it to throw her brutally against a block of ruins. Gamera arrived in turn, ready to collide with Gigan again, but the latter had foreseen the case and with a flick of his tail diverted Gamera from her trajectory and sent her crashing further away. Seeing the titans in difficulty, Elsa wanted to go help them and Godzilla, with a grunt and a nod, told her to do so, that he would recover quickly. Kong, Rodan and Behemoth, still suffering but conscious, joined the king of monsters to protect him in the event that Gigan came to attack him. Elsa thanked them with a look then spread her ice wings and flew towards the fight.

Kiryu, despite the damage to his mechanical body, got up and resumed the duel with Gigan, the blades clashing even more. Then, with another electric punch to the face, he managed to stun Gigan, long enough to manage to pierce his head from bottom to top through the jaw with his blade. Sparks exploded from the cracks, Gigan emitting staccato metallic groans, like malfunctions, but still managing to stay up. Seeing an opening, Kiryu activated his most powerful weapon. A very concentrated blue energy was first concentrated in his tail, rising little by little as his torso opened, revealing a large cannon which then fired a huge blue laser beam which pierced Gigan's body, leaving only 'a gaping hole in the middle.

Staggering, suffering very serious damage and crackling all over, Gigan nevertheless seemed not to give up and nevertheless tried to fire one of his cannons. But Gamera came from behind, tearing the arm apart with his jaws in a mechanical tear. Mothra also arrived, spewing a veil of sticky silk which like a net engulfed Gigan's body and arms, immobilizing him. Then, to strengthen the hold, Elsa arrived in her dragon form and spat a powerful breath of ice which covered Gigan from the feet to the neck. Trapped, the alien cyborg nevertheless continued to shake its head, roaring and animated by its program.

From the Tartaros sector in Castle Bravo base, Serizawa and the others had watched the fight live and everyone seemed relieved to see the alien cyborg captured. And it was time, the stat check screen indicating that Kiryu only had thirty seconds left.

_"Kiryu fulfilled its role well." breathed Serizawa, reassured. "You can send helicopters to bring it back to base."

_"Understood sir." said one of the scientists.

Suddenly, Kiryu's control screen went crazy, turning red and sounding like an alert with a single phrase: system override.

_"What the...?!" the scientist gasped.

_"What is happening?!" Serizawa asked.

_"I don't understand! All of Kiryu's systems are going crazy! We're completely losing control!" said the team leader.

Ann, James, Shego and Ron really didn't like the way the situation was going and this was accentuated when Kim, initially silent and calm, suddenly began to be agitated and moaning, as if in pain and the helmet control on his head emitting disturbing sparks.

_"KIM!" Ron, Ann and James gasped in unison.

Shego reacted and tried to forcefully remove the helmet from Kim's head but received a violent electric shock to her hands which hurt her and forced her to step back. The electric sparks grew stronger and hotter, almost forming a cage around Kim who continued to scream. James then grabs Serizawa by the collar.

_"Serizawa, take that thing off her! It'll kill her!" he shouted in distress.

Serizawa was totally lost, unable to understand what was happening.

Meanwhile, Kim opened her eyes. She was still sitting in the control seat, but no longer in the base. She was in a huge, dark, infinite space. She was no longer in pain, but yet she felt this non-human, powerful and overwhelming presence coming closer. Then, she saw him... these two yellow reptilian eyes opening in the dark, then this immense reptilian head of a titan moving forward and facing her. Although crushed by this presence, Kim did not feel threatened and she then knew what this thing wanted... She had fought hard, but now he was taking over.

Everything went white for Kim, who then woke up among Ron and her parents. Lying on the floor, she had been removed from the chair and the helmet removed from her head. Relief returned to faces as Kim gasped, opening her eyes and sitting up. Immediately, she was hugged by Ron and her parents while Shego stayed behind, arms crossed, but didn't hold back a smile.

_"Oh sweetie, I thought we were going to lose you." cried Ann, reassured.

_"I'm fine, don't worry." Kim replied.

_"Don't ever scare me like that again... is that understood?!" Ron begged in tears.

Touched, Kim promised him by kissing him tenderly on the mouth. Serizawa then walked towards her.

_"But... What happened?"

_"I'm not sure, but... I think Kiryu has a new pilot now." was the answer Kim gave, to everyone's astonishment.

In New York, Kiryu remained active, but seemed to act differently from before, seeming more...autonomous. Immediately, Elsa, finding herself near him, felt the soul which now animated this metal body. It was like with the first mechagodzilla, but this time, the spirit that inhabited it was protective and familiar. Zilla!

Kiryu walked up to Gigan, looking at him for a moment in silence as if to analyze him. In reality, Zilla's mind was able to see the true nature of this cyborg. He wasn't just a weapon created by a vanished extraterrestrial civilization. The alien steel that composed it was an alloy, created from the exoskeleton of a male Muto once killed by these same aliens when they came to earth a long time ago. This same muto was brought back to the moon, its body dissected, its exoskeleton altered into a new metal in order to create a cybernetic titan powerful enough to defeat the titans of the earth. By this alloy composed of his own body, the soul of the Muto had lived, imprisoned in this eternal cage, driven mad by this alteration of his being and his death as brutal as it was vain. The suffering that emanated from him was matched only by this madness that kept him alive and its programs that forced him to act against his will. Kiryu decided to put an end to his torment and with a sharp and precise blow of his wrist blade, decapitated Gigan, his head falling heavily at his feet. The visor on Gigan's head stopped glowing, his shrill cries gave way to silence, and his body gradually stopped moving. Having accomplished this duty, Kiryu turned his gaze towards Elsa for a moment, giving her a brief nod, then the mecha plunged into sleep mode, drained of its energy. Elsa felt it. Zilla's soul was gone.

_"Thank you my friend." she thought, a tight in the heart.

However, Rodan arrived and, showing himself to be much less compassionate than the others, with a brutal movement of his wings unleashed a powerful and burning shock wave that exploded the ice, and consequently, Gigan's entire body, into thousands of fragments. which dispersed in the air. Once done, the fire titan, with a dark growl, backed away and perched on a ruin. An enemy had been defeated, but the battle was far from won.

************

In the Void dimension, the fight between Maui and Chernabog continued. As their weapons clashed, the demigod could also see the cataclysmic consequences that would result from the opening of the wormhole.

_"Look around, you fool!" he said. "If reality breaks, we will all die, including you!"

_"So be it!" roared the mad demon. "I'm taking you all with me!"

Maui could see that Chernabog had completely lost all sense of reality, he was nothing but a living chaos without reasoning, like his titanic abomination he had created. Suddenly, Chernabog managed to seriously wound Maui in the shoulder with his blade, then with an extremely violent punch, knocked the demigod out of the air and sent him crashing to the ground. Maui groaned in pain, bleeding from his shoulder and trying to retrieve his fishing hook nearby, but Chernabog appeared from the air, striking him again with force.

_"Farewell, miserable vermin!" Chernabog growled, ready to finish off his enemy.

Suddenly, a person came running at full speed in their direction. Jia, whose eyes were adorned with an intense white glow and some sort of strange glowing white symbols appeared on his arms. Emerging with speed, Jia stopped Chernabog's movement and placed his hand firmly on the demon's forehead, who immediately screamed in intense pain, as if he were being burned, and backed away. A smoking burn mark appeared on his flesh. Chernabog, destabilized, then saw Jia in front of him. The young girl no longer showed any fear towards him, on the contrary, she openly challenged him, driven by her desire to protect those she loves and the power of the Titan of Life. Maui got up, supported by Moana as Anna arrived alongside Jia.

_"No! She can't..." growled the demon.

_"You were so stubborn in holding this power, demon, that you neglected its true nature." Anna said with conviction. "You could never have obtained it because unlike you, Jia knew how to find the true nature of this power. Something you never had: a heart."

Although injured, Chernabog roared in fury and wanted to attack again, but Maui intervened, locking the demon in a wrestling hold and beginning to force it back towards the edge of the nearby infernal vortex.

_"Let's continue this fight at your home, demon!" Maui growled, struggling with all his might.

_"No way! Now that I'm there, I'm staying there!" roared Chernabog in his madness.

With his black blade, Chernabog then violently pierced Maui's body before the horrified eyes of the others. The demigod, despite the shock and intense pain, did not loosen his grip and struggled to push the demon back even further. However, the impact of Jia's power on Chernabog had another effect. Managing to finally free itself from the body of the demon, the soul of the god Lucanger was able to fly away.

_"MAUI!" Moana yelled, wanting to go help him.

_"You're welcome..." Maui then said, taking one last look and one last smile towards her and the others.

Then, drawing on what remained of his strength, Maui leapt, holding Chernabog tightly, who was then blocked and roaring in despair, both falling under the shocked gazes of Jia, Anna and Moana through the infernal maelstrom of the vortex and disappearing in the storm of flames. Moana couldn't believe it even after seeing it... Chernabog was gone, but so was her friend Maui.

But it wasn't over. The infernal vortex began to get smaller and smaller, but its suction grew stronger and stronger. No longer able to resist, Jia, Anna and Moana were on the verge of being swallowed by the tunnel of hell. Suddenly, a colossal and familiar roar rang out and it was with shock mixed with hope that Anna saw the spirit of Zilla emerge powerfully from the water, with the Fairy Godmother on his back.

_"Hang on!" she yelled at them.

Holding hands, the three girls jumped to cling with all their strength to the backbones of Zilla, who while running and with his strength and his weight of titan, was able to resist the attractive force of the vortex long enough for it closes definitively, cutting off any chance of Chernabog being able to return and thus stopping the threat of seeing reality shatter.
