That sounds fine just keep in mind any character scientist wise would answer to the head scientist. So they would be like a tier or two under Eric if that makes sense.

As for natural form  usually it is human. At least any form I've seen has had a natural form of human, it's the type of shifting that is different.
You can have it be easy like a werewolf or horrifying where they shed blobs of their previous form. Along with that you can either do human shifting or animal shifting.

Edit: also yes make a sheet if they will be used often.
