War Machines Without End (Commander SI)

I died from an incurable disease. Lucky for me, I was given a second chance, and now I am a Commander. What is a Commander? I am a 15-meter-tall Brutally Efficient Self-Replicating Machine of War. I am a machine that can conquer a galaxy. I am a machine that can easily crack a planet if given time. I am a war machine that can fight against an infinite swarm like the Tyranids and the Zerg. I am THE COMMANDER! ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Disclaimer! This is a self-fulfillment fic! It is a Crack! You've been warned.
