The Serum

On top of one of the walls, there was the Survey Corps and David.

The main characters were wondering what the Thunder Spears were for, so they asked Hange.

Hange said that it was a secret as David told her not to reveal what they were capable of as that would get rid of the element of surprise.

When it was discovered that Ymir was Titan shifter, David was contacted immediately as he may know more about this titan.

He also realised that this was the moment that Reiner and Bertholdt revealed their true identity.

So he carried with him five poison darts to incapacitate them both.

As the two Warriors saw their target, they began walking over to him.

David had just finished explaining to the Scouts the powers of all nine titans.

They were in shock of the powers that David had and realised that they could not afford to have him as their enemy.

Little did they know that the next few moments may be their last.

MC POV

So the Warriors are approaching me, huh? Let them come, I've five darts with your name one them.

Reiner spoke.

"You must be David Bastian, I'm Reiner Braun, and this Bertholdt Hoover. We are the Colossal and Arm -"

"Is that a fucking monkey?"

I pretended to look shocked.

The duo turned their heads, and I immediately got out two darts.

That's when they turned back, Bertholdt was stabbed in the shoulder and passed out whilst looking shocked.

Reiner blocked my dart with his injured arm and began transforming.

I spartan kicked him off the wall and watched as he transformed.

Everyone was in shock as they saw Reiner Braun transform into the Armoured Titan.

The main characters were in denial.

I spoke.

"Erwin, leave him to me."

He nodded at my words.

I cut my hand with my knife in order to transform into my Titan.

As I transformed, I picked up Bertholdt, and Reiner watched as I ate him.

Human meat tastes pretty good.

The reason why I ate him was because I remembered that I could transform into different Titan forms.

The other reason is that the Colossal Titan is an opponent. I can't really fight against it unless I find a way to distract it.

Reiner watched as I ate his best friend. He must be seething with rage right now.

I looked at him in a mocking way as I hardened my fists and jumped down.

When I got down, I began walking towards him and soon ran at him.

He blocked, and I jumped at him and broke, tried punching his face, but his arm blocked it.

As a result, the Armour in his arms broke, so he turned his defence into offence.

He began punching me, but I blocked every punch.

After a few punches, I moved out of the way and pulled his arm so I could punch him in the face.

His face armour broke, and his right eye stopped glowing.

I got a bit too confident and dodged his attacks with ease.

He went for my legs and I jumped then he turned back and ran at me.

I moved to the side and went for a punch. He used the technique as I used and punched me in the face, which broke my jaw.

I was sent flying into the wall, and a few bones were cracked.

Reiner then broke all his armoured plates and began running.

I exited my Titan form and looked at Reiner. I know he's coming back, but he won't be alone.

The Beast and Cart Titan will be there. I really hope they come so that it saves me the time hunting them down.

The Scouts came, still shocked at what they were seeing.

"Listen, we have to prepare ourselves. There's a chance more Titan Shifters will appear or worse, Marley will attack, so we have to make preparations."

They all nodded at my words.

Later, we were on top of the walls discussing our plans.

Connie then spoke.

"Uh, Mr Bastian, sir, what should we do now?"

I looked at him.

"You guys train harder than you ever have, and Hange will give you Thunder Spears."

They all looked confused on what Thunder Spear was, so Hange explained to them what it was.

Meanwhile, Ymir woke up, and everyone started questioning her.

I informed her about her Titan Power and her curse. She looked distraught at her short lifespan.

Historia hugged as she was worried for her safety, much to the happiness and excitement of Ymir, which cured her depression.

The others were silent, upset at the betrayal of their two closest friends

Mikasa had a burning look on her face. She probably blames them for Eren's death.

I was excited about using the power of the Colossal Titan. It was a literal god of destruction.

I decided to try to make a short speech in order for them to be more useful and determined.

"Look, guys, I understand that you are upset about your two friends being your enemies. But you can't let that get in your way. These are the people who caused the death of your loved ones and pretended to be your friend."

I continued with a quote from God Of War.

"Do not allow yourselves to feel for them. They will not feel for you."

And with that, I walked off.

A few days later, I shared my knowledge with people in the walls. Making books about science and technology.

These books were used in schools.

However, the government ordered all schools to get rid of these books.

The people were angry at this and began protesting.

My workers were sick and tired of the government, and I decided it was time for a change.

So, while in my base, I decided to make a speech.

The crowd in front of me was trained in combat by me and was also trained in the use of anti-personel vertical manoeuvring equipment.

"Alright, listen up, people. I see that you are all pissed off and angry at the government, and so am I. These people are idiots. They have held us back for a long time and made us weak and vulnerable."

My crowd of workers agreed with me, saying that every word I said was true.

"These people are traitors to Eldia, and when I tried helping the people by giving them new and useful knowledge, they proceeded to ban every book of it. Enough is enough."

The crowd listened with anticipation.

"We will go back to our home and fight for Eldia l, the king is that sits on the throne is only a puppet. The true king is Rod Reiss."

I showed them a drawing of him. The crowd glared at the picture.

"This man is a traitor to all of us here. The thought of him being one of us sickens me. Soon, he will face the consequences of his actions. I give all of you my word that I will bring back the Eldian Empire, and once more, Eldia will rule with its Titans."

The crowd began yelling.

"FOR ELDIA!!!!"

I smiled, such control and influence I have. I really am amazing.

My secretary Ban came to me and told me that they had found the Titan.

Immediately, I came to where the Titan was, and I saw it. Dina Fritz's pure Titan.

It was bound by countless wires. I made contact with it, and a surge of power flew through me.

For a brief moment, I saw a glowing tree in the middle of nowhere. There were only stars.

This was the path. In front of me was none other than Ymir Fritz herself.

Behind her, the glowing tree had only six tree branches, which showed that there were only six Titan shifters.

Then I was back in the real world.

When I saw Ban, I could see a worm in him. It was the same worm in Eldian Spines, but it was not glowing.

I tried activating through my mind, and it worked.

A bolt of lightning hit Ban and an ugly ass Titan. I mentally commanded it to kneel before me, and it did.

The workers came to see where the lightning came from, and they were stunned at what they saw.

I told them about my powers, and they looked at me in awe.

Then, a few days passed, and I was making a serum capable of strengthening a human body.

After so long, it was completed. I injected it within myself.

I was filled with pain, and my bones started to crack. My healing abilities kicked in, and my bones were starting to break, and heal.

I was experiencing a lot of pain in my body, but in a few minutes, the pain slowly started to stop.

I got up and placed my hand on a table to which the table broke.

My excitement started to grow, and I went outside and punched a tree.

My workers saw this and were in shock at my superhuman powers.

My speed exceeded that of a normal human. It was almost as if I was teleporting.

I would say that my superhuman powers rivalled that of Albert Wesker.

Then I heard horses, and I looked back. It was the Levi Squad.

Petra spoke first.

"Erwin wanted to warn you about the military police. They are demanding you to turn yourself in, and they have captured Historia."

They told me about who Historia truly is.

"Thanks for telling me."

I turned to face my workers.

"Well people l, looks like we have our chance at punishing the traitors."

All of them looked excited and began gearing up.

I smiled. Let the civil war begin.
