This is one of Merlin's new characters - Glyph the Synth. Merlin created him(?) after dreaming about having a Synth fullsuit. Exactly how they'll fit into Merlin's swords-and-sorcery comic world remains to be seen, but I'm sure it's only a matter of time.

This was drawn by and coloured by me. This being a Synth I did the lighting myself, though I did use Ahro's highlights as a reference to establish the light direction.
The Synth species was created by Vader-San.
