Gloids

Strange creatures from an alternate dimension, the Gloids recently have begun randomly appearing due to tears in the space time continuum. Careful examination of their anatomy and DNA show they are a possible evolutionary offshoot of humanity.

Gloatmeal

The strange creatures known as Gloatmeals are trans-dimensional entities capable of  freely moving through multiple universes as a fish moves through water. Part of the hazards of entering another dimension is one's physical attributes must conform to the physical laws of said dimension. Thus in our dimension, these otherwise glorious beings appear as sentient blobs of oatmeal like substance. This does nothing to curb their astronomically huge egos.

Chromia

Chromias are smallish, multidimensional entities which are capable of moving through dimensional barriers at will. As they are not truly "native" to this dimension, how they appear to us is a mere projection. Chromias speak with each other by rapidly changing various color patterns on their skin, although they are capable of communicating with other races through a limited form of telepathy.

Lassu

Lassu are strange creatures. They appear as serpents with feathery wings, a strange bulbous rattle, and an oddly human head. They have been known to display supernatural powers, such as mind reading, clairvoyance, teleportation, and the ability to fly though solid objects. They do not seem to be confined by the same laws of physics which govern the rest of the universe, leading some paranormal researchers to theorize they are multidimensional entities capable of moving outside of space-time. As to who they are and what their ultimate purpose is, no one can say.
