Nezu Ogon

Nezu Ogon are an old type of Ogon. They are a metallic colored dark grey Koi. As with other Ogons, the color should be uniform throughout the fish. Also, look for any signs of previous damage, for any scars will take away from any Ogon's look.

Helmet Head?

Nezu Ogons have a dark area on the center of their heads. This has caused many breeders and Koi keepers to affectionatly nickname them Helmet Head. The dark area almost looks like a maruten spot, but is it usually not very uniform in color and does not have sharp edges.
