Metal Titan (Attack On Titan Fanfic)

I do not know how I am here, why I am here or who else is here but I do know that I am in a world full of tall naked humans that do not care for my existance. I can turn into one of them yet I do not have skin. I am purely...... Metal

Warning: Swears. I do not own Attack On Titan or Hashirama and Madara just the plot and my OC.
