When threatened by another monster, Aknosom will open up its crest, lower its head, and cover its entire body with its wings to make itself look bigger. At night, locals often mistake it for some kind of evil spirit due to its unique silhouette and giant "eye."

On the tips of its wings are feathered scales that it can open and close, much like its crest. When folded or layered together, these feathered scales can act as a shield that'll protect Aknosom from incoming attacks. When unfolded or swung, they become sharp blades.

Aknosom has a large umbrella-shaped crest, or comb, on its head that it can freely open and close like a fan. A smaller crest, which has an eyeball-like motif, can be found on its forehead.
