Same species, different concepts. Real characters are built out of more than one word.

Theres a common thing in larp where some people feel like they need to play some random or exotic type of animal and that that makes their character somehow more interesting and that multiples of the same thing are boreing... completely untrue! If they've really put thought into developinga character, its impossible for it to be like anyone else even if they are the same kind of critter.

(shown are several fox characters from my local larp.)
