if you wanna make fanart or payments or whatever i'll usually want art of these guys the most sooo yeah - max, patches and lizzy can all be drawn feral or anthro, and they can have any outfit you want. Premade outfits: https://scratch.mit.edu/projects/1382502360 - oobleck can only be drawn as feral - Cyrus, nightmare, lyra and bella can only be drawn anthro - Mr. klez can only be drawn anthro, and he always has the same outfit
the (thing) each character has is which oc universe they're from, so if they have the same thingy below their name it means they're from the same universe :)
