Dirk Strider X reader (demigod)

Slowly changing Pt.1

I turned around and found calypso free. She ran towards me and was about to stab me. But I got of her way and knocked her out with my sword.
"(Y/n) you are not on their side, you are not evil"

The voice said in my head, I shook my head and began to focus.
Then monsters already surrendered all the demigods. Except Frank. They was no way out now. The monsters watched them with their sharp glare.

"(Y/n) you are not evil!" Piper said.
I flew to the sky.
"Quite you foolish and useless girl. Your charmspeak won't work on me. Unless your lesbian" I barked at her.
"Say Frank would you come out of your  hiding spot and drop your weapon" I used charmspeak.
Frank did what I told him and he was a little mouse. He turned into himself. He dropped his spear.
"Good now. Go join your friends " I waved him off.
He followed.
"How come these monsters listen to you?"Annabeth asked.
I stayed quiet.
"She became their  leader " Percy answered for me.
"Percy your right. I did become their leader" I said.
"Hurt them" I ordered.
Then Annabeth looked at me and I saw her grey eyes.
"(Y/n) promise me when you take over the monsters as their Leader, don't let them hurt Annabeth Chase" Luke made me promise.
"I promise if you only teach me how to be a really good leader and all your tricks" I smiled at him. He messed up my hair and gave me a hug.
"Okay I will"

Then I spoke.
"Don't hurt Annabeth "
They all looked at me in surprised.

Percy tried to attack the monsters.

"Percy! I mean Dear Brother. Would you stop trying to attack my monsters. Or I will let them hurt Annabeth. Or I could hurt her really bad. " I said.
"You wouldn't" Percy looked at me.
I made the wind pick Annabeth up and she flew to the air. I flew to her and grabbed her by the neck with one hand. It's amazing how I picked her up with only one hand and she is older than me.
I flew up into the clouds and dropped her. Then I teleported on the building. Percy saw me and he gasped. They all gasped.
"Where's Annabeth?!" He yelled.
Just then we all saw her falling in the sky and screaming. I saw a tear escape his eyes. I suddenly felt sorry for him.
No (y/n) you can't feel remember.
I said to myself.
"Frank get her!" Percy ordered.
I made leaves grow on him.
"No no. Frank listen to me " surprisingly he listens.
"Please (y/n). I c-can't lose her again " Percy words touched me.
What does he mean lose her again?

"I will only save her if you will make a deal with me." I said. Annabeth was close to the groundm.
"..."
"Annabeth is close to her death." I smirked.
"Okay! I will make the deal!" He said.
I smiled at him and flew to get Annabeth. I caught her in time and landed her next to Percy.
"Lets go" I open the shadow-travel thing and all the monsters went in.
I saw Percy and Annabeth hugging.
Then something clicked in me but I didn't know what.
"Till next time Jackson! Remember you will accept any deal I make. See ya later!" I waved and left.

Percy p.o.v

I saw my only sister besides my other one. Leave. She has turned completely evil and there's no way to stop her. She's just too powerful.
I hugged my Annie. The thought of losing her scared me.
"I'm sorry Percy " she cried.
"N-no it's not your fault. You were right about her. I should just forget about her" I cried.
Everyone looked worried.
"No she's your sister. We need to help her and the only way to do that is find out who was with her the whole time" Annabeth said.
"No. She's too powerful. I almost lost you and I don't know what she will do to you or any of you guys. I'm scared of what she is capable of" I said.
"No we will help her, Percy. She belongs with her brother " Piper encourage me.
I stood up and helped Annabeth. Then I saw Calypso getting up. We all ran to her. I helped get up.
"Ugh. What happened? Did she leave?"
I nodded my head.
I saw red stain on her shirt and turned her around. I saw that the back of her head was bleeding.
"(Y/n) must of hit you really hard" I touched her head.
"Ouch!" She yelped.
"Sorry!"
"Where's Leo ?" She asked.
She tried to walk.
She stumbled and I caught her before she fell. I saw that there were marks on her legs. (Y/n) must've made the vines grow on her legs deep.
"You shouldn't walk Calypso." I gently hand her over to Frank. Frank picked her up.
"Guys where are you?!" Leo screamed.
"Here!" Hazel yelled at him.
Jason and Leo showed up with mud all over. Leo looked at Calypso and ran to her.
"Oh my gosh! What happened to her?!" Leo yelled.
"(Y/n) made the vines go deep in her legs." Hazel answered.
"I will hurt her. Until she fe-" Leo sword in .
"No. I will not allow you to hurt my sister. She is not evil." I defended her.
I gave Leo a glare and looked at him in his eyes.
Leo draw his fist down.
"Fine" he grumbled.
Everyone looked at me and of course I was their leader.
"That goes for everyone too. Any one of you beat her or hurt her in anyway. You will regret it immediately." I said firmly.

(Y/n) P.o.v

I was on a throne in a old castle. I don't know how this castle got here and how the monsters knew it was here.
This was Kronos army or what's left of it. The monsters that survived the war was forced to be hiding and not come out when I came back. Since then they been waiting for me or at least a hope that I was still evil. I still felt a little different. That different was GOOD. I thought about how I am free now so Kronos can't tell me how to feel. But part of me still wanted to be bad and take revenge for Iapetus.
