Um... right, here goes. This might be a difficult one

*EDITED OUT WHILE I REWRITE A BIT BETTER, PLEASE STAND BY, K*

Okay here goes!

Your heroes cannot hear me
They cannot even perceive me
But you can
Further into the heat of the moment
As you fight for your life
I'll still be around a little more
I've had many names
You've read many names
Or maybe just one, it depends on the tongue
