Zara's POV

I didn't want to fight my brother. I had to though to save Cade, Y/n, and the others. I held one of the sword of the original primes and back slashed my brother's chest as he hissed in pain.

"Enough, Optimus!!" I yelled as I held my sword up to him.

"Either you surrender or die. Please do not pick die because this sword..." I stated as I placed the sharp tip of the sword at his neck cable."Can easily kill a Prime that betrays it's kind." I finished as I raised my sword.

He looked like he was going to pick the wrong option, and I knew it. So as I was ready to slash him, he upper cut in my jaw which sent me flying back. I hit the ground hard as I went rolling a yard away from him.

I groaned as I weakly sat up but was only might by another blow to my helm.

"S-Stop. D-Don't d-do t-t-this." I tried say but it only came out in a fit of chokes as he placed his heavy ped on my chassis.

"Forgive me, sister. But you are no use for me anymore." I couldn't believe the words that were coming out of his mouth. What's worse was that he grabbed my sword and held up at the direct point of my spark. I let enegron tears run down my faceplate as Optimus stabbed me in my spark and I automatically wen into power down. Forever.

"OPTIMUS!! WHAT HAVE YOU DONE!!"

Flashback

Third Person POV

Optimus rode on the dirt road as he spotted a few vehicles up ahead. One was a familiar vehicle he been waiting to see.

"Mr. Leader of The Free Galaxy's back. I knew you make it. I never had a doubt." Cross hairs said as he ran up to Optimus.

"We got your call. We've been waiting." Drift greeted as Zara pulled up next to Optimus.

"Hell yeah!!" Hound shouted from a huge cliff away from them.

Optimus then transformed after Cade, Shane, Tessa, and Y/n hopped out. He looked at his fellow comrades then at his sister.

"Hello, Optimus."

"Zara??"

"You two know each other??" They both heard as they looked down at Cade.

"He's my brother."

"She's my sister." The Prime siblings said in unison before sharing a laugh.

"Cade Yeager. They're my daughters, Tessa and Y/n. That's speed racer, Shane." Cade said as the Prime sister nodded and smiled.

"You want to know something, Zara, right??" Y/n asked as Zara nodded. Y/n gestured her to lower her audio sensors.

"No offense to your brother, but, you're a lot more more cooler than him. He's very...um, how do I put this??" Y/n whispered as Zara giggled while looking at her confused brother.

"Very strict and soldier-ly??" Zara whispered back as Y/n nodded and they both shared a laugh.

"Its good to have you back, brother." Zara said as she smiled at the brother Prime.

Optimus smiled back before looking down at Y/n who was still in fits of laughs.
