He is a "Blade Runner", a special member of the Los Angeles Police Department whose job is to hunt and "retire" replicants which have been declared illegal on Earth.
- The Alcoholic: It's much faster to count the scenes in which Deckard isn't drinking.
- Anti-Hero: Deckard isn't the most likeable of guys, and his job of executing the Ambiguously Human replicants is ambiguously moral.
- Artificial Human: Maybe. Still widely discussed even today.
- Badass Longcoat: Deckard's single-breasted brown trenchcoat, which he wears in almost every scene he's in, has become so iconic you can easily find replicas of it online. As well as giving him the classic Hardboiled Detective look, it's practical in a city where it never stops raining.
- Born Lucky: Luck is what ultimately saves him from the replicants: he would have been killed by Zhora had witnesses not stepped in, by Leon had Rachel not intervened, and Roy if he hadn't taken pity on him.
- Cool Guns: Which is both futuristically devastating and old-school looking.
- Defective Detective: Not only is he plagued with self-loathing and doubt, he becomes increasingly unsure that his role as Blade Runner is ethical, and eventually becomes a fugitive with Rachael.
- Hardboiled Detective: He is more of a deconstruction, being an Anti-Hero with some serious psychological conflicts.
- One Last Job: Bryant convinces him to come out of retirement on the grounds that he's the most capable man who's available at the time. He grudgingly agrees to do it.
- Perma Stubble: He is a noirish Anti-Hero, after all—it's basically part of the uniform. The film takes place over the course of several nights, and he doesn't stop to shave.
- Pragmatic Hero: His methods are questionable, but he takes no pleasure in killing and feels genuine remorse for his targets.
- Punch Clock Hero: He doesn't particularly like his job as a police officer who's more or less a bounty hunter. His reason for taking on the assignment in the film is as a favour to Bryant and because he's the best man for the job.
Rachael is the latest experiment of Eldon Tyrell. Tyrell believes that as the replicants have such a limited lifespan, they have little time to develop control of their emotions, causing difficulty managing them. He believes implanting them with memories would create a cushion which would allow for emotional development, and make them more controllable. Rachael has the implanted memories of Tyrell's niece, and she is led to believe that she is human. It is not revealed in the film how long she has been living, but Tyrell admits that he thinks she is beginning to suspect the truth of her existence. When Rachael learns the truth, she is ignored by Tyrell. In desperation, she turns to Deckard, who has been told by Captain Bryant to retire her. He eventually falls in love with her.
- Ambiguously Human: It's not revealed she's a replicant at first until she takes the Voight-Kampff test. Even she doesn't know - only Tyrell does.
- Artificial Human: Like all replicants are.
- Big Damn Heroes: When she blows Leon's head off to save Deckard.
- Clones Are People Too: She's more or less Tyrell's pet project, a replicant designed to be as human-like as possible and to have a more complex backstory (in the form of implanted memories) than the others. He treats her like a human and she never suspects she isn't one until Deckard shows up.
- Defrosting Ice Queen: It takes a while before she and Deckard finally get it over with and kiss. And even then, he was rather rough with her.
- Do Androids Dream?: As the most human-like of the replicants in appearance and personality, it's pretty much impossible to tell she is, in fact, an artificial life-form.
- Emotionless Girl: She has a very cool demeanour towards Deckard at first, but this breaks down after she learns she's a replicant and finds it hard to take.
- Fake Memories: They're really memories from Tyrell's niece.
- Letting Her Hair Down: She does this in Deckard's apartment.
- Only One Name: Unlike the other replicants, her last name, assuming she has one, is never stated. (In the book it was Rosen.)
- Pretty in Mink She has a fur coat which she wears at the end of the film
- Ridiculously Human Robots: Rachael takes this trope pretty far: she's a Replicant who thinks she is human. When Deckard tests the machine on Rachael, it takes over one hundred questions for him to determine she is a Replicant (it takes only twenty or thirty, normally).
- Robot Girl: Being more or less the Tyrell Corporation's robotic Sexy Secretary.
- Smoking Is Cool: In fitting with the Film Noir aesthetic of the movie, there are several scenes where she smokes cigarettes.
- Transferable Memory: All her childhood memories aren't real.
Roy Batty is the leader of the renegade Nexus-6 replicants and the main antagonist of the film. He is highly intelligent, fast, and skilled at combat, and yet still learning how to deal with developing emotions. With an A Physical Level (superhuman strength & endurance) and an A Mental Level (genius-level intellect), he is probably the most dangerous of all the fugitive replicants. He is a combat model, used off-world for military service. He and five other replicants come to Earth, hoping to find a way to lengthen their life span.
- Genius Bruiser Both the smartest replicant and also very strong and fast.
- I Just Want to Be Normal: Like all of the replicants, his goal is just to live a normal life instead of being a slave and dying before his time.
- Ridiculously Human Robots: Being a Nexus-6.
- Self-Made Orphan: Kills Tyrell after being told by his creator that there's no way to have a longer lifespan.
- Smart People Play Chess: Under Roy Batty's guidance, Sebastian checkmates Tyrell in two moves.
- The Spock: He normally controls his emotions very well, though he does fly into a rage at Tyrell, and has a emotional attachment to Pris.
- Super Strength: Strong enough to lift Deckard with one arm, at least.
- Trans Human: Being an artificial human who's been engineered to be better than the real thing, well..
- White Hair, Black Heart: His blond, almost white hair and his past as a killer (he doesn't specify, but he said he's done questionable things).
She is a "basic pleasure model". She is the girlfriend of Roy Batty. At an A Physical Level, she is shown to have superhuman endurance (as in the scene where she grabs a boiling egg with her bare hand without harm). Her B Mental Level puts her at a lower intellectual level than Roy.

Leon Kowalski is a replicant who came to Earth with five others looking to extend their lives. He has an A physical level, which enables him to have superhuman strength and endurance (according to the Final Cut he was used as a 180 kg/400 lb nuclear-head loader in the outer space colonies as well as a front-line soldier). Leon is classified mental level C. He doesn't have the speed of thought that Roy does when it comes to solving problems.
Dr. Eldon Tyrell
Played by: Joe Turkel
Dr. Eldon Tyrell is the genius who has built up the large
Tyrell Corporation. He is the creator of the Replicants.
- Affably Evil: At best he's morally grey, but he befriends Deckard quickly and treats Roy with respect, even though Roy had invaded his home to make his demands.
- Bigger Bad: In some ways he's more of a villain than Roy is.
- Corrupt Corporate Executive: His creations seem to disagree with the ethics of creating sapient beings that are doomed to a short life of hard labour.
- Eye Scream: In combination with this, he gets his head crushed by Roy.
- Four Eyes, Zero Soul: Tyrell wears thick glasses and is responsible for exploiting the life he creates with forced servitude and short lifespans.
- Mad Scientist: A brilliant scientist who doesn't stop to think that creating artificial humans with emotions and personalities might backfire on him someday.
- Smart People Play Chess: Has an ongoing game with J.F. Sebastian.
- Smart People Wear Glasses: He's never seen without his bifocals.
- Too Dumb to Live: When your angry, vengeful creation is confronting you and demanding you perform a medical procedure on him, the correct answer is not to explain why that procedure would be fatal, it's to perform it anyway. Possibly justified in that his idolization of Roy as his ultimate creation may have been stronger than his self-preservation.
- Wicked Cultured: He comes across as more highbrow and intelligent than most of the other characters do (except possibly Roy).
- Villain with Good Publicity: His company appears to be quite profitably, and nobody seems to complain about its business ethics of using robot slaves.
A genetic designer working for Tyrell. He is not allowed to emigrate off-world .
- Dropped a Bridge on Him: Killed offscreen by the replicants.
- Nice Guy: To the point of Good Is Dumb. He goes out of his way to help the replicants out of the kindness of his heart, shelters them, gets them their coveted audience with Tyrell, and look what he gets out of it.
- Not So Different: He agrees to help the replicants meet Tyrell because he's sympathetic to them from having a genetic disorder which gives him a shorter lifespan just like they have.
- Smart People Play Chess: Has an ongoing game with Tyrell, who beats him regularly.
- You Have Outlived Your Usefulness: Killed by Roy after gaining access to Tyrell's chambers.
- Younger Than They Look: Has Methuselah Syndrome. Because of this he ages faster and has a shorter life span, something he has in common with the replicants. He looks over fifty when he's in fact in his twenties
Played by: M Emmet Walsh
Deckard's former supervisor from his time as a blade runner, who calls Rick in for One Last Job
Played by: Edward James Olmos
An enigmatic officer in the L.A. police department who detains Deckard, and fills the role of his 'partner' of sorts on Deckard's quest for the Nexus-Six replicants.
- Bowties Are Cool: You know, for a cop, his preferred style of dress is much more evocative of some sort of high-end drug dealer.
- Deadpan Snarker: While he doesn't speak a whole lot, a few scenes do have Gaff seem like he is silently mocking Deckard. It could just be he doesn't like him all that much, but it's really hard to say given how little we see or know about him.
- Enigmatic Minion: Again, Gaff doesn't talk that much, and he doesn't seem particularly enthusiastic about helping Deckard on his mission. Given the nature of this movie, this has lead to a great deal of Wild Mass Guessing as to what role exactly he plays in the movie's narrative.
- The Quiet One: What is not spoken in LA's futuristic 'Cityspeak' dialect (which Olmos has confirmed to be an offshoot of Hungarian mixed with several other languages, mainly born of cultural convergence within the future city of L.A.) is spoken through his origami figurines. And those open up a whole bunch of Epileptic Trees all by themselves...
- Secret Keeper: Whatever else is debatable, Gaff is strongly implied to know about Rachael, but for some reason, lets her and Deckard escape together. It could have been a moment of compassion on Gaff's part, since he knows Rachael will not live past her expiration date... or it could be his motive is more sinister, or quite simply he knows something we don't.
- Sharp-Dressed Man: As noted above. Bonus points for wearing a flower on his jacket in one scene.
