After the battle with Annie, Eren found himself in the room he was placed in, in order to recover.
The entire place was quiet. Everyone was off doing their work, training and doing chores. Eren was alone in his room, barely awake and just staring at the ceiling because that's the only think he can even do.

Eren felt exhausted. Physically and Emotionally. One of his allies has betrayed him and slaughtered dozens if not hundreds of his fellow soldiers with cold blood. It was too much for him to take in.

Suddenly the door bursted open. Eren saw a man with a black cloak rushing inside the room. The mysterious figure picked Eren up by the shoulder and ran out of the room. Mikasa who happened to be going to Eren's room to check on him as usual, saw the cloaked figure sprinting away with Eren on his shoulder.

Eren screamed "Mikasa!" as he was being taken away from her. Mikasa ran with all her speed towards the mysterious figure knowing full well the repercussions, but even with her unmatched skills, she was unable to catch either of them.

The mysterious figure used 3dm gear once he got outside and thrusted away into the distance. Eren, who was still trying to escape from the cloaked figure's grasp, saw the scouts chasing them with full speed. But suddenly, and as the scouts were close to Eren, a magical portal opened in the sky and the cloaked figure entered it with Eren on his shoulder.

As soon as they entered the mysterious portal, It suddenly closed, leaving the scouts with no clue as to what has just happened. Mikasa arrived after getting geared up along with Levi and the rest of her squad mates. She was baffled by what the units described to her what happened.

The mysterious figure placed Eren gently on the ground and waited for him to stand up. Eren did so and looked around him, only to see himself surrounded by pure white.
Wherever Eren looked, there was only the color white to be seen.

Eren then looked at the mysterious figure and asked: "Who the hell are you and where are we now?!" In an angry tone.

The mysterious figure took off the hoodie of his black cloak, only to reveal something impossible. The mysterious figure turned out to be Eren.

Eren, the one who got kidnapped looked at what seemed to be his doppelgänger staring at him in complete shock. He could only stare. As if he was looking at his reflection. Only this is not a reflection.

"I am you. And this is not a joke. And we are literally nowhere." The mysterious Eren spoke as he looked around him.

"Wha... who... why do you look like me?!" Eren asked in a confused and slightly angry tone.

The other Eren sighed. "I don't 'look' like you. I. AM. YOU." He said in a rather calm tone.

"This cannot be! I must be dreaming. Someone snap me out of this!" The first Eren exclaimed.

"No you are not in a dream. I will explain to you what's happening. But I need you to listen carefully." The second Eren replied.

"Ok... Proceed."

"Do you know that there is not one reality? There are an infinite number of realities and in each reality exists an Eren Jaeger just like us. We're both the same person but from different realities. Each reality is different from the other in various ways. You have different outcomes for every choice you make. You have different situations and different stories. We co-exist in a multiverse in which each reality exist without the interference of another. For instance..." the second Eren removed the cloak he was wearing, only to reveal a Military Police Brigade uniform under it.

The first Eren stared at the uniform in complete bewilderment. His eyes never went off the green unicorn symbol on the shoulder of his other self.

"What is this? Why are you wearing the MP uniform?" The first Eren asked.

"See? This is what I'm trying to explain. In different realities you choose different paths, live different lives. I chose to join the Military Police Brigade while you chose to join the scouts." The second Eren said as he pointed at himself then at the original Eren while explaining.

"I would never join the Military Police. Never." Said the first Eren.

"You decided to join the scouts while other Erens joined the Stationary Guard and I joined the MPs. Some didn't even sign up to the 104th cadet corps! Isn't this amazing?" Said the Second Eren.

"Ok. All of that aside. Why am I here? Why did you... hop... out of your world or whatever and come to mine, kidnap me and take me here?" The first Eren asked.

"Well, here's where it gets scary. You see, there is one particular Eren, who was a scout. He started to control his titan form and gained new abilities somehow. He became selfish and power hungry and I still don't know why. No one in his reality was able to stop him. He killed a lot of scouts, garrisons and the MPs. He found the means to move from reality to reality and even create his own titans and control them. He started hunting for more power across realities and murdered dozens of Erens, Annies, and other Titan shifters. He seeks Infinite Power and immortality. If we don't stop him, everyone we know will die. Including Armin and Mikasa" Eren of the Military Police explained.

"Oh no... Mikasa..." Eren the kidnapped said as he started to think about Mikasa and weep silently, knowing all the trouble he was pulled into. Eren the second approached him and placed his hand on his shoulder and said: "That's why I am here. To recruit you and other Erens to fight him. We must take him down once and for all."

The first Eren looked at him and said: "What's the plan?"

"We are to go and recruit a third Eren. We'll go to this reality where we became a stationary guard. This Eren will most likely be guarding the walls of trost. We have to get him to join us somehow." The MP Eren stated.

"And by that you mean kidnap him and get chased by the survey corps, huh?" Eren the first asked.

"Sorry about that. I knew that you would not come with me the easy way so this was the only way. It was risky, I admit, but I pulled it off. You're welcome." Eren of the MPs replied.

After their little chat, a portal opened which seemed to be done by a device attached to the left arm of the Military Police Eren.

"Come on!" MP Eren said as he walked through the portal.

They both got through the portal with no problem. The first Eren walked into a new and different universe only to be horrified by the sight of Trost being under attack once again, this time from the 3 infamous Titan shifters. The colossal, the armored and Annie.
Eren the scout did not have any thrusters on so Eren the MP had to carry him to the armored titan's location. They landed on a building and spectated the fight only to stay hidden and try to locate the third Eren without being seen. The native Eren in titan form was fighting the armored Titan and was losing.

Both the scout and the MP Erens saw that Mikasa, Armin and Jean from that particular reality were trying to help Titan Eren but their efforts were futile. So the both of them reluctantly decided to interfere. They both jumped down the building and shifted to titans mid-air. Lightning struck them and steam formed everywhere. Then the two Titan Erens emerged, attacking the armored Titan. Mikasa, Armin and Jean stopped fighting and thrusted to a nearby rooftop.

"Wait... is there three Yaegers right there?!" Jean asked. Mikasa looked at all of them dumbfounded and speechless.

"How can that be possible?!" Armin exclaimed.

The three Erens teamed up to take down the Armored Titan. They punched and kicked him everywhere, leaving his armor in bits and pieces on the ground. The Armored Titan came to the conclusion that he is unable to continue the fight, released steam from his mouth and body and disappeared.

The three titans then ran towards Annie's Titan form. One of them punched her in the face so hard he sent her flying. When she got up and looked at them, her eyes widened. She put on her fighting stance and waited for them to rush at her. Two Erens did rush at her but one just stood there and then sneaked to Annie's back. He grabbed her by her hips and threw her to the ground. She crystallized herself and made a run for it.

All three Erens chased her. They ran as fast as they can to try to catch her but she was slightly faster. As soon as they got close to catch her, the colossal titan stepped in front of them, blocking their way.

They started to climb his leg in order to reach his head but he then suddenly roared and released steam from his body. Mikasa came thrusting towards them but the steam knocked her off balance and blinded her, making her fall on a rooftop.

She looked up and saw that the colossal titan is nowhere to be found. The three Titans fell down and didn't get up. Then Eren the MP emerged from his titan and ran towards Eren the scout who emerged unconscious. Mikasa thrusted towards the native Eren and hugged him. Eren the scout suddenly awoke and looked at MP Eren.

"They got away. But this Eren is unharmed. Let's go and get him." Said Eren the MP as he wrapped Eren the scout's arm around his shoulders and walked towards Eren 3.

Mikasa looked at them and gasped. "Eren..." she said in a soft, confused and dumbfounded voice. Eren the scout spoke and said: "No time to explain. We need this Eren to come with us. It's very important."

Mikasa shook her head and said "I don't know who you are, I don't know what you want, and I will never let Eren go with you, you imposters!" She said as she pulled one of her blades on them.

"Whoa! Whoa! Hey!!! Calm down, Mikasa! Let me explain." The Military Police Blockhead said as he started to explain his mission.

"If Eren is going then I am going too." She said firmly after hearing the entire story.

"Can you bear witness to the death of an Eren right in front of you? Our mission is to kill that evil Eren and stop him from destroying the realities! Let him come with us!" Eren the scout yelled the last part.

Eren the garrison soldier suddenly woke up and looked at the two Erens. His eyes widened. Eren the Military Police soldier sighed and started explaining all over again.

"OK. I'm coming with you." Eren of the garrisons said.

"No! Eren! I won't let you!" Mikasa shouted.

"I AM NOT YOUR BROTHER OR YOUR SON, MIKASA! STOP INTERFERING!" Yelled the native Eren, sharing his anger trait with his other counterparts.

"Some things just don't change, even between realities" Eren the scout joked.

The two dimension-traveling Yeagers pulled the garrison Eren by his wrists and dragged him to a portal that opened as a result of MP Eren's command. After they got in, the portal closed.

All three Erens walked inside the white inter-dimensional realm that they were in until they approached two other people. The two other people were also Erens from other realities. One of them looked a little taller than the three and wore his red scarf, resembling Mikasa. He also wore a shirt similar to hers. The other was a female Eren. The two approached the three Erens. The female Eren spoke. "So you got Eren Prime himself and garrison Eren, huh? Good!" She exclaimed in a cheerful manner.

Eren the scout and Eren of the garrison asked her: "Who are you?!" Both at the same time.

"I'm Erika. I'm you, but a girl." She replied. "Literally. That's just it!"

"I'm Eren. The same as you but I didn't give Mikasa my scarf. Instead I gave her a jacket. Her parents didn't die that night but were killed by titans in the fall of wall maria." He said with a voice so dead that it reminded them of Mikasa. But more Eren than Mikasa.

"I call him, Stone-Cold Eren. Because he's as cold-hearted and as strong as Mikasa. Maybe even stronger, considering his titan powers." Erika said.

"Eren Prime? What does that mean? Why am I Eren Prime?" Eren Prime asked.

"Well you are the mainstream dimension Eren. The realities all start as one main reality and then they split into different realities and timelines based on the choices and events we make and/or happen. You are the Eren from that main reality. So that's why you're Eren Prime." The cold-hearted Eren explained.

"This is just getting more and more complicated." Said Eren the garrison, scratching the back of his head.

"Now that were all here, let's give ourselves special names to differentiate between one another." The Military Police Eren stated..

Eren 1 - Eren Prime
Eren 2 - MP Eren
Eren 3 - Garrison Eren.
Erika is Eren 4
Eren 5 - Stone-cold Eren.

MP Eren then said: "Now all we have to do now is to recruit two more Erens and fully assemble the Eren corps!"

A portal suddenly opened. All 5 Erens entered it and went into Eren prime's reality.
