His robes look a little too light to be a Helmasaur, since they're more of an orange than yellow, but that's a good point. Though I think they would've made his eye parts darker in that case as well, like they did with the Mask-Mimic, but it doesn't have to be perfect. Though the Gemesaur King might have been a better idea. As for the Bee Guy...I seriously doubt it. Too minor a role.
