The wierdly dressed Zur En Arrh Batman Skin comes from the alternate version of Batman seen in several comics. Batman of Zur-En-Arrh is in fact a backup personality of Bruce Wayne's - to be used in cases of extreme psychological trauma. This version of Batman is a lot more psychotic, and sees visions of a creature called Bat-Mite, among other apparations.
Bob mentioned the epic Ramayana, which is itself the story of a “superhero” — the god Rama, who does some pretty nifty stunts, along with his brother Lakshama and monkey hero side-kick Hanuman (my personal favorite). I think he’s probably right about Asia being the earliest origins of superheroism; Hinduism is one of the world’s oldest religions and it’s full of larger-than-life men/gods who right wrongs and fight for truth and justice.
The practice may have originated in a Celtic festival, held on 31 October–1 November, to mark the beginning of winter. It was called Samhain in Ireland, Scotland and the Isle of Man, and Calan Gaeaf in Wales, Cornwall and Brittany. The festival is believed to have pre-Christian roots. After the Christianization of Ireland in the 5th century, some of these customs may have been retained in the Christian observance of All Hallows' Eve in that region—which continued to be called Samhain/Calan Gaeaf—blending the traditions of their ancestors with Christian ones. It was seen as a liminal time, when the spirits or fairies (the Aos Sí), and the souls of the dead, could more easily come into our world. It was believed that the Aos Sí needed to be propitiated to ensure that the people and their livestock survived the winter.
