@ Although they don't actually need a structural body, they often form a body form out of status need. @ The anatomy of their eyes contains dark matter we haven't been able to decipher yet @ The slits on the sides of their faces and in the mouth area are purely for communication and interaction. @ they live up to 2500 years old with earth time, but they continue to exist with a space-time concept far beyond our perceptions. This is because they can travel in a dimension independent of space-time with the wormholes they created to travel. @ Of course, as we expect from any alien formation, they can make all kinds of changes on their own cells. They can appear in any form and color.

In addition to all these, there is no obstacle to their being a strong world icon with their features and a thematically developable scenario.
