Was the blade runner himself a replicant?
Yes. No. Green.

According to Ridley Scott, yes, Deckard was a Replicant. It was hinted at in the movie when it first came out which resulted in a lot of controversy. The final cut version, which came out in 2007, was tweaked slightly to make that fact much more obvious.
If you read the book, “Do Androids Dream of Electric Sheep” you’ll find out that the goal of the Rosen Corp. (aka the Tyrell Corp. in the movie) was to replace all humanity with Replicants.
Reading the book and watching the movie really make a more complete picture of what the author was painting. I invite everyone to take the time to read the book.
Precisely. "You know the score, Pal? You ain't Cops, you're Little People!"
as a few have said here yes and ridley scoot confirmed it.
there is a load of hints in both movies. here is a few
all replicants collect family photos (the fake family they are given to ‘cope’ with their creation...deckard’s house is filled with these to an extreme level.
rachel play the piano thinking she learned it in her childhood...just like deckard.
tyrell almost tells him when deckard is interiewing rachel. he smiles at deckard when asked ‘how can it not know what it is?’ and tyrell answers ‘more human than human’. tyrell asks how many questions it takes and deckard replies 30-40 cross referenced but for rachel it was more than a 100. this really means tyrell is working to create a nexus line that is totally indistinguishable from human...you would never know even with the test..the implication is decard is one of these. the mind warping in the movie is truly fantastic...was deckard just created? did he even exist before the noodle meetup with gaff? was all of the past just implanted? was he and the team just created to kill roy and the off worlders with their own short lifespan? the implication is that all the blade runner units are actually replicants hunting replicants.
rachel asks deckard has he ever taken the test (the voight/kampf test that tests eye movement etc) ..he hasnt
there is a lot to imply that the nexus 7 line is making the nexus 8 and humans are kinda out of the loop. we have been bypassed in brain power. look for example where the people who made the nexus line are now living. they eye designer (’if you could have seen what i have seen with your eyes)’ is not exactly swimming in money. when pris meets the designer he is proud of the fact that he ‘made’ the nexus 7 (there is part of me in you i think is the comment). although he is still involved with tyrell...does he look and act like someone at the pinnicle of his career?, nope he doesnt. also roy batty, a soldier for off world wars...one designed for battle and war...even he has brain power equal to and probably exceeding tyrell himself...he beats tyrell at chess, with almost no experience he jousts with tyrell on how to genetically change himself to stop dying...humans are no longer top dog in the brain game. also roy kills his god. i am sure i dont have to spell out the implications of that scenario.
in the movie deckard knows/is told about the spider story rachel thinks is her own, that memory was taken from tyrells niece and implanted in rachel. deckard the hard nosed detective daydreams about unicorns in the extended version and gaff the police man with a limp leaves an origami unicorn for him at the end. gaff is probably human and is aware of who is actually who (i.e. who is real and who is the nexus line). he knows deckard dreams of unicorns...he is letting deckard know what he is with the unicorn at the end. now if you really want to extend this out...how would gaff know he dreams of unicorns, perhaps told or....unless gaff dreams of unicorns, so ....is deckard a nexus copy of the injured gaff and his memories? have they taken the police experience of gaff and implanted them in a working body to hunt replicants...?? a stretch i know...but this is why blade runner is such a fantastic movie. once you get even marginally below the surface it really deals with the arrival of AI. Since you are you because of your memories...well how do you know right now know you are human and are not simply a nexus model from tyrell corporation?
...its is truly a fascinating movie...and you can look at it as a police chase and be happy or..far far deeper...
