Just a doodle exploring one possible look for an armor suit formed from Oki's polymorphic body. While physically fused with Spectre, she and Oki still have two separate bodies, and they must work either with or around each other, depending upon the situation.

The primary mass of Oki's body is protected by Spectre's body and her chitinous scales, but in some rare instances and extreme cases, An additional layer of protection is needed. Fortunately, Oki can modify the shape, density, and consistency of his protrusions, so an effective armor can actually be formed.

Just the sketch of an idea. Critique welcome.
