Black Siddha is a comic series created by Pat Mills and published in the British anthology Judge Dredd Megazine.
The story revolves around a super-powered Deva knight, Mardaka (literally "who crushes" or "who makes suffer"), who is "known and feared as the Black Siddha".
[1] Black Siddha centers on Rohan, a young Hindu British Asian, who is revealed to be a reincarnation of the titular character, a brutal warrior who enjoyed killing but nevertheless held to a chivalric code.
Mardaka's superpowers are known as siddhas, and amongst others he has the siddhi of sky-striding and armoured skin.
He fights using an Urumi, a double-edged flexible sword, although his has magical qualities.
