He Is The Dark Knight

A bat sign aloft the dark sky,
A shriek of terror, a distress cry;
A flutter approaching evil's legion,
A black bat silhouette, Gotham's guardian.

Peace and justice always disrupted
Fighting for it this man knows no tired
Be it the Joker, Riddler, or Penguin Man
The cape crusader vanquishes them at the end

Still some who perceived him as the villain
Blamed for crimes, slaughter and disdain;
Yet he took the blames without complain,
And took no praise, no accolades gain.

Everytime when the signal is lighted,
Fear not that it may not be sighted;
Bad guys out there, better flee and flight
You'll have no chance against Gotham's Dark Knight
