Secret Identity

I am the mask before the man,
I guard the identity,
Who's behind me?
What's behind me?
What about me?
I feel the pain of every blow,
I am the cowl of the bat,
The cape of the man of steel,
The web of the friendly neighborhood wall crawler,
I am spandex,
I am bulletproof,
I am the superhero,
Without me,
Flying reporters,
Crime fighting millionaires,
Web slinging teenagers,
I am the X in X-Men,
Who Watches the Watchmen?
I do.
