Author's Notes: It has always been a topic for discussion among my friends how Attack on Titan is so similar to Pacific Rim. This is my interpretation of how the two stories will come together. The timeline at the start of this story is from Attack on Titan chapter 51 onwards and towards the end of Pacific Rim, just moments before Gipsy and Striker attack the Breach. This is also presuming that Striker Eureka was not destroyed. Also Cherno Alpha's and Crimson Typhoon's crews are still alive.


"So this is it?" Commander Pixis asked

"Yes, this is the Forbidden Gateway," Historia answered, her small frame dwarfed by the gigantic gate in front of them. "The origin of the Titans is beyond here."

Historia stood in awe at the head of the hastily assembled combined forces of the Scouting Legion, the Garrison and the Military Police.

Her family had always stressed the significance of the Forbidden Gateway, but never in her wildest imagination would she have visualized such a magnificent piece of engineering. Who would have ever thought that the key to ending the entire Titan War was to be found in the thickest portion of Wall Rose? A gate of reinforced metal never before seen in the world, inscribed with ancient texts of warning.

Such a structure called for great attention. Even after the high mortality rate the Scouting Legion suffered from rescuing her, they were only further spurred to discover what was in the basement of Eren's house. A last-ditch effort was made and the Legion committed its entire force in a blitzkrieg towards Shiganshina District. Their retrieval mission cost them dearly, now only 34 members of the Legion remained.

But all they discovered in the basement was a key. One that Historia had been charged to find since birth.

Now all the sacrifices humanity has made over the past 5 years have culminated in this one moment.

Historia looked back. Every eye was on her, every hand was on their blade, ready to leap into high-speed combat at any moment. Her comrades from what remained of the former 104th Trainee Squad stood at her back. Jean, Connie, Sasha, Armin, Mikasa and most importantly Eren. The anxiety in their eyes made her shiver. Eren was especially nervous. His father had left this world to travel beyond this very gate.

"I'm opening the gate now." She announced.

A flurry of sharp movements erupted behind her as every single soldier readied cannon, rifle and 3D Gear.

She inserted the silver key into an oddly-shaped hole which was most likely the keyhole.

There was a loud hiss, steam bellowed from vents in the side of the gate. The massive block of metal was slowly lifted into the air by old pulleys. Bright sparks of energy rippled over the surface behind the gate. A freezing gust of air blew through the small opening, bathing everyone in an ice-cold spray of water.

No one was prepared for the sight they would see.

A sea.

"A-Armin," Eren nudged his friend "Remember the time you were talking about the outside world? About how the world was covered by the sea?"

The frail boy nodded, his mouth gaped at the spectacular sight before them.

Their dreams had finally come true. A vast expanse of water lay before them, just beyond the gate. The outside world was never beyond the walls, but within them.

Even Commander Pixis was staring in amazement with Commander Erwin beside him.

"T-this is incredible."

Then the grandeur of the sea was cut short.

"Movement in the water!"

Everyone suddenly sprung into combat stance. A massive ripple of water the size of a house was moving towards them at a lightning-fast rate. Water was thrown into the air as a massive beast emerged from the water, crashing through the gate like it was paper. Flashbacks of the horrors from when the Colossal Titan first blew a hole in the walls struck everyone.

With a deafening roar, the beast announced itself. It stood as tall as the wall itself. Similar to a bull in form, it stood on its hind legs. Tough grey armor plating covered its scaly body. Orange stripes streaked across reptilian-like skin. A massive forked tail swept over the heads of the stunned humans. It had four menacing eyes, two on each side of its head, staring down upon the tiny humans. It was bleeding a strange luminescent blue blood. It poised its human-like arms with huge claws for fingers.

The Colossal Titan would be considered short in comparison to this beast.

This was true monster.

After a brief exchange of curious glances, the beast let out another roar and brought its massive hands up, preparing to attack.

"ALL UNITS, ATTACK!"

Levi's squad charged into action first. They fired their grappling hooks at the skin of the beast, blasting themselves towards its head as cannon fire whipped overhead. The shots did no damage and only irritated the beast more. It placed a massive foot forward and crushed the cannon batteries in a single stomp.

The hooks of the 3D Gear suddenly lost their grip as the muscles of the beast moved. Everyone attached to it lost their grip and fell.

But Mikasa was the first to recover. She twirled in the air and fired another hook at the beast's arm. Yelling her battle cry, she slashed at the beast. She however, did not expect her blades to break. The steel shattered upon the armor plating. The force shoved her backwards and she tumbled through the air.

"Mikasa!" Eren yelled.

He diverted from his attack to save her.

Levi was next to line himself up for an attack. He shot his hands to the right, creating momentum for his signature spinning attack. His attack drew blood. Yet the armor of the beast was too tough and his blades broke too. For the first time, the legendary Levi was spinning out of control as his attack was shrugged off.

Pixis and Erwin watched from afar.

"There's no way we can harm that beast!" Erwin cried.

"We can't retreat now! Continue the attack!"
Pixis was out of his mind. But there was no retreat for them. This one beast alone could do a hundred times more damage than all the Titan attacks combined.

To their horror, another ripple of water was forming behind the beast.

This time however, a loud horn marked the arrival of a second beast. Bright lights broke the surface and a huge figure stood up. A huge metal Titan had arrived.

It had a single eye in a "W" shape, made of tessellated yellow glass. The Titan had a crude painting of a scantily-clad woman on its right breastplate and it stood like an arrogant Military Police soldier. It too was badly damaged, metal supports showing beneath crushed plates of armor.

Eren and Mikasa were on the ground just a few hundred meters from it. Mikasa recalled how she had first seen Eren as a Titan when she had almost given up all hope of living. She grabbed his arm as she realized this time there was no friend in that Titan.

"ALL UNITS, FALL BACK!" Pixis bellowed.

Mikasa and Eren were too far. They held onto each other and prepared themselves for the end.

The Metal Titan unexpectedly raised its fist. The first beast turned its head towards the newcomer. The fist of the Metal Titan went soaring through the air and into the face of the beast, a trail of fire behind its elbow.

The beast roared in pain.

It had no time to rest as the Metal Titan's hand morphed into a cannon spewing a strange blue energy. 3 sharp cracks followed as balls of blue fire burned through the chest of the beast. The angry beast grabbed hold of the cannon and used its other hand to pierce into the side of the Metal Titan.

The Metal Titan retaliated as out from its other hand came a modular blade that emanated a low buzzing sound. It rammed the blade into the skull of the beast as both fell to the ground.

Mikasa grabbed Eren and sped away just as the beast and the Titan hit the ground. The sheer force of the impact blew them out of the air. The two were hurled onto a relatively flat piece of land, tumbling upon impact. A huge cloud of dust was kicked up.

When it subsided, Eren was lying face-flat on the ground. Mikasa picked him up.
"Eren! Eren, are you injured?"

"No, I'm fine. What about the others?"

Mikasa scanned the area.

The Metal Titan and the beast were laying side-by-side, blue blood oozing from the beast's head, burning the ground where it flowed. Both of them lay absolutely still.

The remaining soldiers were picking themselves up. But a squad of Military Police soldiers and Commander Pixis were riding towards the two corpses.

Jean landed beside Pixis and Erwin.

"Alright, the Titans are down, now let's go finish them!"

Jean's leader instincts kicked in and he rallied some soldiers and they used their 3D gear to land on the Metal Titan, as the beast was clearly dead. He was just about to wind himself up for an attack on the Metal Titan's neck when he heard a faint voice coming from its eye.

Marco. Marco

Jean was stunned. He turned his gaze to the source of the voice

"Jean, what gives?" Connie landed beside him

"I… I thought I heard someone call out for Marco."

"But Marco is dead-"

The voice was heard again.

Both soldiers looked at each other. They wasted no time in heading towards the voice.

They fired their gears beside the eye of the Titan.

Two shadowy figures were beside the broken glass eye. One was kneeling and holding the other's body up. They had a strange head, clad in black armor with a silver spine protruding from their backs.

Jean and Connie approached slowly, swords ready to cut down the strange figures should they be hostile. The one kneeling placed down the body and took of its head, revealing a human head underneath. A man with blonde hair removed the head of the other to reveal a young woman with black hair, partially dyed with blue on both sides of her hair.

"A human?!" Jean couldn't believe his eyes

He recalled how Eren had emerged from the back of the Titan, as did Annie. He gripped his swords tighter. But Connie grabbed his arm.

"Jean wait."

The blonde man spoke in the same voice they had heard earlier.

"Mako! Mako!"

The woman coughed as she came back to life.

"I'm alright, Raleigh."

She giggled a bit before embracing the man.

Now Jean was confused. So the man was calling out for his partner and not Marco.

The two Scouting Legion soldiers lowered their weapons and approached the two. At first the two reeled back into a defensive stance, but when they saw human faces, they lowered their guard, albeit perplexed as if they've seen a ghost.

There was an awkward pause as both sides tried to comprehend the fact that there were humans beyond their world.

Finally, the blonde man spoke into his helmet.

"LOCCENT… we have human contact in the Breach."
