Answer:
You heard me before, yet you hear me again, then I die. Until you call me again.
What turns from red to black as soon as it touches water?
I make you weak at the worst of all times. I keep you safe, I keep you fine. I make your hands sweat. And your heart grow cold. I visit the weak, but seldom the bold.
I follow the orders of only two. I respect the work of only two. I am in constant battles with many, Though one surpassed them all. With forces joined, We created hell, Until our mutual enemy fell. Who am I?
What goes in the water red, and comes out black?
All about, but cannot be seen, Can be captured, cannot be held, No throat, but can be heard. Who am I?
