@Gira: i think you already saw his strength. what you faced was the unchained Horus. the GEW version had to be toned down to be fair. got rid of all magical abilities and kept what he had left within reasonable strength. i didn't want to repeat the Bane incident....man did i mess up with him...
@ CS: why thank you. i'm glad you like him despite his strange eating habits
@IK: they glow whitish gold on the actual character. as for his eyes, imagine a glowing version of Ratholos' eyes, but with white pupils and gold iris instead of black pupils and orange iris. as for the patterns around the eyes, they're meant to resemble the Eye of Horus egyptian symbol [notice the brow in the symbol is shown in the form of his main horns, and the two white parts under the eye represent the most notable part of the symbol itself, though inverted].
@ G4E: thanks. and DeviantArt is easy to operate. you add art via a button in your profile page...
