My name is Zero. 

I am a Reploid. 

On my world, we are both loved and hated by humanity. Some of us protect the 
humans and each other from those of us that suffer from a form of madness, 
Mavricks or Irregulars. 

The wars between us have gone on for many years... too many... they've taken the 
lives of many friends from me. 

Web Spider, Magma Dragoon, The Colonel... 

Iris. I held her in my arms as she died from the wounds I'd inflicted on her, the 
smile on her face fading and the shine in her eyes going dull. 

And if I had not ended up here, it would have happened to X too... now that I 
know what I am... what I was built for and why. 

I can not go back... not to that world of sadness and darkness. As strange as it 
is... the light I see here... it gives me such energy when I see it in their 
eyes. Ash, Ryini, Ambika, Jun... there is something in their eyes that I have not 
seen in mine or in any of my world... all of my life. 

I want to ensure that that light... that... hope... will always be there (and 
even though Ambika may not see it herself, it IS there, in her eyes). I will do 
that, by staying here. Where my madness fades... and perhaps, my sins can be 
attoned by Guarding... The Heart.
