Ok, that makes sense, even if it is a tad disappointing.
II agree with that, it also raises the interesting question of why some bioware is inherently unnatural its impossible to create a transhuman with it.
"Yeah this is just a little pet project of mine I grabbed some SINless guy off the streets and turned him into an anthrpomorphic foxgirl (Cats eyes 0.1, Tail 0.25, Claws 0.1, Fangs 0.1, Sex Change 0, Metatype Modification Severe 0.25, Sensative Skin 0. Total: 0.
Well ok it has to be at birth without GM changing things still turning an unborn human boy into an anthropomorphic foxgirl only costs 0.8 of the free essence leaving you with 0.2 to make other changes to her. Only slightly more than a rating 1 adrenal pump or synaptic booster which you can't afford to get a rating 2 of and geneware doesn't apply at all.
Hmmm I've now a vague for a plot hook, brilliant scientist trying to create prototype transhumans out of grown adults (island of Dr Moreau) grabs "SINless" street kid and experiements on them because they are bioware compatible. Said street kid is actually the runway son of a powerful CORP member who hires the runners to get them back. Of course when/if the runners finally find him/them he's now an elk/fox/rabbit/X anthropomorph naturally and possibly not even a he. The other problem being that this is now the subjects natural state and turning them back without the DR's (preferably destroyed equipment although black trenchcoat types may have gotten it intact) is going to involve essence loss. Failing to turn them back is going to involve explaining to the corp member that his son really is this X and then of course you have whoever was financing the Dr and any other companies who may find out what he succeded in doing wanting those records. Sure the Dr was a crackpot trying to create a harem of anthropomorphic animal girls but revise the process somewhat and you can bioware supersoldiers who are not suffering any essence loss allowing even further modifcations to them later.
