Merlin

I create soldiers of the future
Merciless and bloodthirsty
Without fear of death
Brutal constructor
I'm scientist of genius
Invulnerable
They can't burn in fire
Never drawn in water
Nothing can kill my boys
They got a tortoise shell
Brains taken form a shark
All they can do is killing
Killing without end
Soldiers of my dream
Murderers invincible
Indifferent to life
Without fear of death
