Well, since I have been sketching so much on Deva's new design style, I felt like trying to design the look of a male of her species ( still need to figure out a name for this demon breed )

The males look a little different from the females. Size and strenght wise they are equal, differing from person to person rather than gender. Strenght and extra skills getting stronger depending on their level and ranks in Hell.
The females though are often more aggressive and wild of nature since their natural skills are connected with nature catastrophics and elements like that. The males natural skills are manipulation of mind, mostly mortals and human and often behind big wars and the alike started by mortals.

The males can move and raise their scales as well but only those pointing backwards. All facial and front scales are more soft and cannot be raised like the rest. A design by nature to avoid they hurt the female doing the mating. Though the front scales being more soft they are quite vulnverable towards the females razor sharp, raise-able scales covering her whole body.
They don't got as big scale plates either as seen on Deva, but instead got spikes or horns. Still pointing backwards.
