As the title states, this is an original character that I designed known as The Symmorian, Master of Cosmic Balance.
It is supposed to be the universal concept of balance given physical form. The open faced portion is known as Thetus, and represents logic, law, order, etc... The full helmed portion is known as Crossian, and represents emotion, anarchy, chaos, etc...
The best way to encounter this being is to deal with them together, as trying to parlay with them separately, is extremely dangerous.
Enjoy mates:
Thetus


Crossian
