From Post-Self

Devonian is a furry cladist who, upon uploading with a catalogue of dozens of fursoñas, found themself to be human. They are able to fork into various singular forms, but do not seem to have a choice as to which, and surmise that it is based upon mood. When they merge down, their down-tree instance winds up with aspects of whatever species it was that they had forked out (for instance, on forking a blackbird, some black feathers are added to their down-tree instance).
