Unknown is the opposite of known. It is known for being unknown, as usual, and unknown people are commonly referred to as misfits or unpopular people (since no one could care to think up a better name).
The Race Edit
There is a race of people called The Unknowns which unknowingly travel in Antarctica on speedboats with free wifi connectivity along the way. This race of people tend to have a brownish-red skinned appearance, blue hair, eyes that are always the color of teal and the shape of a square, and a nose with three nostrils. They do not have a mouth.
Their population is known to be about 15.
