The König is the Bear King. The Bears he rules are probably the same creatures as the Swartzwalders from The Works, where he was referred to as the Bärenkönig, but neither they nor he have been addressed as such in the comic yet. He carries a gold crown on a chain around his neck, presumably intended to be worn by the Bears' Master, and has a shoulder-guard emblazoned with a capital "F". His chosen armament is a giant curved saber with a blade as long as a man's height.
"König" is German for "King."
The Works Edit
The instructions for the Bärenkönig card (Bear, King) indicate that its replacement is to be played face down.
