Mr. Pangu

The Horrifying Mr. Pangu has not yet shown himself in person to any of the protagonists, but the ever-reliable Kim Kwon-sung has described him as a "goddamn fancy flamboyant male prostitute stupid transvestite Chinese moron poof". He appears to wear bird feathers in all the colours of the rainbow and be a formidable martial artist. And of course is one of the lieutenants of Fu Manchu.
