But for the question, if he's a replicant, you don't even need the unicorn origami, in my opinion.
When I saw the 1982's theatrical (US) cut for the very first time, at age 16, I already thought about, if he's human. I mean, come on, how can a human be so "battered" without beeing heavily injured??
It's was always obvious, that Deckard has super strength.
He seems pretty battered and injured in every version I have seen! His fingers broke rather easily, and he needed saving from the edge of that beam by Batty.
Yes, the fingers, but these are just fingers.
But Leon would have heavily injured a real human and Pris on his shoulders would have sure nearly knocked a real human out, or not?
But Deckard seems nearly 100% okay after the trouble, without the need of a hospital, without broken bones. He got blood in his mouth, but seemingly no teeth lost.
If this all isn't super strenght?
Yeah, I think, a really good trained human with a hard body and additional "heavy bones" could match okay with an average Nexus 6. Army or a Marine, maybe?
But when Leon threw Deckard against the car windshield, would a human take no considerable injuries?
Only one way to find out.
Do you want to throw, or be thrown?!?!?!
A human body can take considerable punishment. And not every punch loosens teeth.
These "is he or isn't he" discussions are my one nerd hobby!
(Star Wars vs Star Trek and Kirk vs Picard, etc., leave me empty).
The correct answers though are Star Wars and Kirk...
