Answer:
I am Invisible Man's drink at snack time
I have feathers that help me fly; with head and body but I'm not alive. Very skinny and a fixed length how far I go depends on your strength.
I speak without a mouth and hear without ears. I have no body but I come alive with wind. What am I?
I cut through evil like a double edged sword and chaos flees at my approach. Balance I single-handedly upraise through battles fought with heart and mind instead of with my gaze.
I can run but not walk. Wherever I go thought follows close behind.
It has no top or bottom, but it can hold flesh, bones, and blood all at the same time.
