Random Riddle: 11-6-2016

I lie down there as you watch me
stick a sword into my head.
You never notice, never see
the description I have said.
My brother who is a twin,
as some people may say,
has an axe behind him
and tries to run away.
We both lie still, the same
beside a pool of red.
We may participate in your game
or amaze people instead.

Who are we?
