[Oh, okay! So, some of these are things I'm guilty of not even bothering with anymore because it's missed so often it feels useless to even bring up, but I'll include some pictures if needed to help! ]
[ Megahes teeth! -HUGE- one there. Goblins usually have your typical shark shaped teeth, Megahes however, doesn't! It's a family trait and no one is sure of where it came from, but his teeth are far more slender and sharp, causing for deeper puncture wounds on his bites! I got the inspiration actually from the Spiderman and Venom comics I use to read a lot in my local Kroger grocery store and it always stuck with me, namely cause I've always been fascinated with Venom's teeth. (Absolutely no idea why!)
[ A fantastic example to go by really! While I love how they also look in the movie, I liked this one far more. Less emphasis on the incisors though, he doesn't have fangs. lol ]
[ Two facts to go! Megahes -hates- the open ocean. He refuses to get on a damned boat if at all possible and even then, he'll fight tooth and nail to find a plane, walk, whatever it is he can, to cross an ocean so long as it's not by boat. Even then, he's uneasy in planes over them too, but at least they're faster and it's not like shit like Kraken's fly...]
[ This is an odd one. While Megahes has nothing against Gnomes, he has a lot of respect for them, it irritates the crap out of him when someone compares his work to a Gnomes work and if one isn't careful, pushing the issue can make him snap violently. To him, good quality engineering/tinkering shouldn't be a matter of what race you are, but a matter of pride. If anything, Megahes takes it as a huge matter of pride that as a goblin, he refuses to cheap out his work and tries to show people that not all Goblins are junk-gineers. ]
[ Thanks for giving the asks back @ghawainearcane! Hope these ended up being some worthwhile facts! ]
