One of the knights on the black side is:
THE FLUKEMAN

Some characters don't find themselves on the "dark" side of this game because they are evil, or the enemy. Many of the sleuths nemesis are natural phenomenon.

Such is the case with the flukeman . Like the "Jersey Devil" and the "Great Mutato" the flukeman is an (un)natural phenomenon. But still, somebody has to be on the other side.
