I need metal to fight with you

I need more metal, || I know,
I bear war || and blood in my heart,
I feel my power, || but fell into your trap
You have control || of me, I'm yours,
I'm near your legs, || but I still
Play by my rules, || you can kill me,
but you can't break || my warrior's spirit.

I need more metal || to continue fight
I need more metal || to find my might
I need more metal || to override my mind
I need more metal...
