I think his retro is dead on to the old gargos but I’m kinda disappointing that his current and retro doesn’t match shago instinct at all not even an accessory set to do so. Wish they would add something to fix that. Kinda kills the immersion to me because that instinct gargos looks so amazing!
A few people have said that that instinct is omens face, not gargos’s. I think that’s a pretty good explanation, but it isn’t my idea.
I think that image was DH original design for gargos which already looks a lot similar to his retro with just more horns, jagged teeth and snubbier nose.
Maybe that was how Jago envisioned Gargos. Not how he actually looked. Just a thought.
