Where are the Terror Twins? (TFA fanfic)

Iacon, mid battle and I was facing almost an army by myself as the others were too scared to fire. No matter what I told them we were told to retreat. No one agreed with me and millions died that day...

I had no one now in days..everyone thought I was the crazy old mech.

But once upon a time, I had someone I cared truly about.

Someone I could count on to be on my side through the darkest moments. To hold me close when I was scared. And vise versa.

Sunstreaker....my twin brother

But he's disappeared....I'm lost without him

(I don't own Transformers animated or most of the characters used in this story)
