This is a triple crossover between the DCEU (Snyderverse), Monsterverse and Atlantis:The Lost Empire. Everything happened exactly as it was in Zack Snyder's Justice League, minus the one bit about Lois being pregnant, the weird air bubble thingies and the Knightmare sequence. I believe Kryptonians, under a yellow sun, can have powers that can rival even Titans and I carried it into this story. After all, Jor-El said his son would be like a god to Earth humans.

The original protagonist was a girl named Guinevere, but after a lot of thinking, I decided to scrap the idea and go on with a new plan, one that involved our very own Mordred.

Nā-maka-o-Kahaʻi is the Hawaiian sea goddess, perhaps the closest thing in Polynesian mythology to the Greek Poseidon.

drapetomania:an overwhelming urge to run away

Long ago, at the Hawaiian coast

The underwater tribal city of Kanaloa was being razed by a terrible current. A beautiful woman was making a quick swim for the shore, a young boy in tow. Her name was Galene, cousin to King Orm Marius of Atlantis and wife to Chief Kāmohoaliʻi of Kanaloa, and the boy was her son, Kalani.

Galene took one last look back at the once prosperous city. Her husband was likely struggling against what caused this disaster, trying to hold it back until the backup from Atlantis arrived. Her injuries were slowly wearing her down but she knew the shore was near, she couldn't stop. Finally, she reached land and placed her son on the white sand. "Remember, Kalani, I love you. I love you, my darling." she sad as she kissed his forehead.

"Don't leave me, Mother!" cried the young boy.

"Forgive me." said Galene, then slipped back under the waves. As life left her, she prayed to both Poseidon and Nā-maka-o-Kahaʻi that they would keep her son safe.

Kalani was left crying on the seashore for several long hours. Under his shirt, a faint glowing could be seen, vaguely in the shape of a nine-tailed fox.

Now

Kalani, now known as Mordred Russell, was on a class trip to Metropolis. Already he missed his Uncle Mark, his Aunt Emma, his best friend and de facto cousin Maddie, and Andrew, rest his soul. His attention was on a nearby news screen, detailing a disaster that had occurred some time ago.

Then suddenly, everyone turned their eyes upward. The calm sunny sky turned into a stormy sky. Mordred looked overhead, then saw thunderclouds. What's going on? he thought, as his homeroom teacher, Ms. Rected, grabbed him by the arm. "Mordred, look out!" Just as she said this, there was a giant sound, like a roar and the last thing everyone saw was a bright flash of light. When Mordred opened his eyes, Ms. Rected was gone and his classmates were running amok. Out of the corner of his eye, he saw a guy looking like a news reporter running towards a nearby phone booth. He sat up, dusted himself off, and tried to stand. For some STRANGE reason, one of his legs were crushed by rubble but it was just sore, the bone wasn't broken.

"Ms. Rected?" asked Mordred, then that was when realization struck. "Oh, no, Ms. Rected!" cried the boy. "Somebody help! Help, please!" he yelled out.

That was his first mistake. The rain puddles around him started to vibrate. He then heard some of the concrete that was still standing fall down. A giant shadow then loomed over him, blocking the light from the flashes of lightning. Turning slowly around, Mordred though he was seeing a true monster for the first time.

He didn't know how right he was.

A gigantic, three-headed, two-tailed golden dragon with massive wings was looming over him. The wings flapped, creating great gusts of wind that made Mordred difficult to stand up, and he made an attempt to run, but then the dragon fired three streams of lightning from its three mouths. Mordred closed his eyes, ready to embrace the impending doom but then...

...something strange happened. He was alive, red spirals and curves painting his body. The fox-shaped birthmark covering his back was glowing as well. His fingernails were now sharp claws, and his teeth were fangs. And somehow, he felt complete. All his life, he felt something was missing, even in his underwater home, even with the Russells. But now, the empty feeling was gone and in its place was a bright, all-encompassing light. Then one of the dragon's two tails slammed onto him, and he heard three voices talking as one, causing his eyes to widen in fear.

"Hatchling? Is that you? You can't hide from us, dear hatchling...why side with these worms? They don't deserve you. We saw you even as we were in our deep slumber feeling your mark, you have been blessed, hatchling, and only we are able to make you into the God you are to be!"

With all his strength, Mordred bit down onto the tail holding him down. The golden dragon screeched in pain, and lifted his tail. Mordred spotted the caped figure emerging out of nowhere and into his line of vision, and began running towards it as fast as he could, the dragon hot on his tail.

Clark Kent, as his heroic alter ego Superman, helped a citizen to his feet then flew him to the cops. "Superman!" a cop called to him, "That's everyone in this area! The rest of the city had already been evacuated by the American Government."

"Got it!" Clark said, then flew at full speed at the menace before firing his heat-vision at the middle head. He dodged, darted and weaved effortlessly between the lightning bolts aimed at him, some he deflected with heat-vision, and cleared the sky with his super-breath before slicing two of the three heads off with heat-vision. That was when a tiny, helpless figure fell into his sight, running towards him. He flew at the kid and made a grab for him but the remaining middle head took advantage of the situation then knocked him down to the ground with a blast of lightning, then scooped the poor kid up in its mouth.

Clark got up and tried to punch the head that snatched the kid away, but the beast had already left, and to Clark's dread, taking the kid with it. The Kryptonian took off, determined to save that kid.

LATER...

How long had he been flying? He had been hot on the golden dragon's tail until nightfall, but he couldn't find the dragon nor the kid. Now he was sitting on a regular-sized reef in the middle of the sea, sighing. The kid's screams still echoed in his head, screams for help that he could not give.

The waves rose around him in a familiar shape, and from them emerged Arthur. "You OK, pal?" asked the Atlantean King.

"I'm fine." said the Kryptonian. "I just...I couldn't save that kid. For that, I feel guilty."

"If that's the case, we could gather the League for that." Arthur declared. "If the kid's done away with, then we sure as hell gonna get back at that...thing, that took him. We Atlanteans are familiar with it."

Later, at the Hall Of Justice where everyone was present, Clark asked Arthur "Tell me more..."

"Long before the age of man, there was this ancient super species named Titans. My friend the Karathen belongs to a subspecies of Titan known as Taniwhas." said Arthur.

"I know some of them." Diana added. "The Amazons' new home, Skull Island, is ruled over by a Titan named Kong, the Protector. His archenemies are the Skull Crawlers, Titans that live underground. Recently, my most esteemed mother took in an orphaned Thunderbird named Nubia, and she became my sister as well as a honorary Amazon."

It was again Arthur's turn to speak. "The Titans have aided us in multiple wars. The King and Queen, Godzilla and Mothra, were good friends of King Atlan. Godzilla even helped us in the battle against Darkseid, during the Golden Age Of Heroes."

"That's so cooooool!" Barry spoke up. Victor only hummed.

Bruce revealed a set of holographics. "A scientist known as Dr. Emma Russell combined bioacoustics of different Titans to create the signal from a device called the Orca."

Clark nodded as he swiped through the holographics, not only showing the blueprints for the Orca but many different Titans as well.

Titanus Volca-Rodan

Titanus Muto-Mayabarb

Titanus Behemoth-Manny

Titanus Scylla-Skyra

Titanus Methuselah-Archie

Titanus Thunderbird-Nubia

Titanus Northern Serpent-Manda

Titanus Taniwha-Karathen

Titanus Skulong-Kong and Rani

Titanus Gariki-Mothra

Titanus Gojira-Godzilla

"Who came up with these names?" Victor asked in amazement while Barry gawked.

"A man known as Dr. Ishiro Serizawa. Recently he came to me, asking me about my connection to the Karathen. From what she told me, they are all able to communicate with a sort of baseline frequency." said Arthur.

"So this frequency can attract them, repel them and even calm them down?" asked Clark.

"You'll get to know in due time." said a female voice.

"Excuse me?" asked Clark. The other five just gave knowing smiles.

"Oh, I'm sorry, I'm Dr. Vivienne Graham. I'm part of Monarch and I know, Mr. Kent, that you are upset but we have thought that the boy you failed to save might be alive."

"Ma'am, with all due respect, please don't give him any hope to crash down, he has a big heart, y'know. He cares for that boy just like he cares for every single person on this planet." said Bruce.

Dr. Graham glared at the bat, "I'm not lying. We believe he just got kidnapped by Monster Zero, or Ghidorah as King Curry might know him. The reason is that he didn't eat him and he may want him for something. We don't know yet but we are asking the Justice League for help for this."

Clark spoke up before anyone could say another word. "Dr. Graham, if there is a way for that boy to be alive, please let me help."

Bruce could only sigh as he saw the familiar fire in his love's eyes. There was no stopping him now.

The wind blew through his face as he was carried in the sky. Mordred didn't know how long, maybe a few long hours, since he was carried off by the three-headed dragon. His eyes were screwed shut by the hard force of the wind. He may not be able to see but he could feel the blood dripping down his left leg. Tears were also dripping down his face as he not only cried at the pain of fangs in his leg but the death of Ms. Rected and the fact that Superman couldn't save him.

With a thump, he felt the dragon land then opened his eyes, to see that they were on an island, that was mostly a mountain. In front of them was a giant opening, big enough for the dragon to go in.

The cave was dark and damp, and the inside was hardly big enough for the dragon to fit all the way in, as he lowered his head to make sure he didn't bump into the stalactites that grew from the ceiling. At first Mordred thought they were at a dead end, but he soon saw a smaller entrance when the head that was carrying him lower him to the ground. He screamed in pain as more blood fell down his leg. The bite mark throbbing in pain as he clutched it. He cast a glance at the dragon, as his two missing heads that Superman sliced off grew back. Then, much to the boy's surprise, the beast began shrinking.

No, he wasn't just getting smaller but was in fact turning human.

In the three-headed dragon's place was now a human. He wore a set of armor that seemed to be made up of his scales with the shoulder pads looking like his dragon heads. His hair was the same golden color as his eyes were the same red. The two tails were still out. Mordred picked up a nearby rock and flung it at the man, only to have it deflected by that damn tail.

He then smirked, "Yes, that's the familiar fire I see in my beloved prince. What a wonderful hatchling." With that he walked towards Mordred, who tried to crawl away but with the pain of his injured leg, he couldn't even make it but a few scoots.

He picked him up, carrying him bridal style, and walked into the smaller entrance. Inside, it was lit up by torches. The walls were marked by scratches and burns, indicating that there was many fights in this cavern. But everything stopped when Mordred noticed someone else was in this room.

Covered in chains, by the neck, wrists, and ankles was a man. He had short black hair that was tinged blue. His teeth, which was surrounded by a frown, were many sharp fangs. His eyes glowed a vibrant orange as he glared at the person who was carrying Mordred. He had many scars, some were in fact still bleeding. But what told the boy that this wasn't human as much as the beast that was carrying him was the tail. Which was flickering back and forth in anger was covered by grayish black scales. The spikes on the tail seemed to glow an electric blue before fading. He, too, wore armor but was made of greyish scales that made him almost look like a king.

A fallen King.

The man's eyes widened when he noticed Mordred. Before they narrowed on the man that was carrying her. To the young Atlantean's surprise, black smoke came pooling out of his mouth.

"Ghidorah, what in the name of Gaia have you done?"
