# How CAN You Justify Melalo's Dorsal Casque?

This, ladies and gentlemen, is Melalo, described in the Book of Creatures website as "the oldest and most feared of Ana's children." His name literally means "filthy", "dirty" or even "obscene". This guy is said to project "anger, rage, cruelty, sadism, frenzy, rape, and insanity" to anyone who crosses paths with him.

Now the focus of the question concerns that weird outgrowth on Melalo's back, which in the official legend is his second head. In real life, however, that "second head" would instead be some kind of casque, like the one you find in hornbills or cassowaries. But bird casques are usually placed on the head, which doesn't affect the hornbill's overall ability to fly.

I have found nothing mentioning that Melalo could fly, but the point of having a casque at the BACK rather than the head still takes precedence. Why would Melalo and his species--or genus--have such a thing on his back?

• Suggestion: maybe include a link to a reference? Even if only in the "citation" or "further info" section of your question? Mar 12 '20 at 0:29
• Not clear what's the premise of your question. Is it "let's assume this is an actual creature. What would be the physiological purpose of the second head?" or "We handwave the second head in. Now, how and to what volition-driven-purpose this mythological creature could use it?" (like: "How does it work in relation to Melalo's victims?"). The science-based and behavior tags seem at odds. (if you try to 'por que no los dos' this, then you have two questions, which may or may be not frown upon here. Even if this is the case, I feel clarifying this explicitly is still needed) Mar 12 '20 at 0:46
