Black King

The Black King is one of the two rulers of Derse and the counterpart to the Black Queen. Though the Black King has not shown up directly in Homestuck, Andrew has alluded to him in his recap of the Homestuck story

While the Black Queen manages the affairs of ruling on Derse, the Black King leads armies in battle against the White King.

Like The Black Queen and White King/Queen, the Black King corresponds to the chess piece with the same name.
