Saint Seiya Omega OC

In Saint Seiya, each knight has a cloth, an armor related to a constellation. In Saint Seiya Omega, the cloths became jewels and receive power over one of the 7 elements: water, earth, fire, wind, lightning, light and darkness.
For my character, his cloth comes from the extinct constellation of Columba, the dove. His element is darkness.
Please know, that I haven't seen everything on Saint Seiya, so I don't know if this has already been done.
