Although she does vaguely resemble a Ludroth, minus the wrong color scheme, are you sure it's from Monster Hunter? Unless it's one of the Frontier exclusives, I know jack about those.

whats wrong with the colour scheme? looks like a Royal Ludroth

totally thought this was Riesz from the thumb

One tag doesn't leave any doubt it's from Monster Hunter :

I guess it's because the green on the Royal Ludroth is just hard to notice. I would have said that R Ludroth isn't green if I hadn't double checked.
