This opening sequence from Blade II is a great example of playing with expectations. The set up is almost identical to the blood rave scene in Blade: some poor schmuck wanders into a den of blood-thirsty vampires. But instead of the Daywalker showing up and saving the day, we learn that this guy isn't a schmuck after all. Jared Nomak isn't terrified by the presence of vamps. As a matter of fact, vampires should be afraid of him! He then proceeds to wipe the floor (and walls) with them. Similar set up, but completely different payoff.
This sequence introduces Nomak as the primary antagonist and establishes him as a formidable opponent for Blade. It actually does a better job in this regard than the first film. Although we see Deacon Frost briefly in the blood rave, he doesn't do much. We have no indication that he's any kind of physical threat—beyond being a vampire. His fighting skills in the big showdown were always a bit sketchy to me.
We even get a little bit of foreshadowing when Nomak talks about not being in contact with his family. Far from a perfect film, but it certainly has its moments.

EXT. COMMUNITY BLOOD BANK - NIGHT PULL BACK from a neon red cross ablaze in the cold December night to REVEAL an inner-city, store-front clinic. Trash and leaves blow over wet, snowy pavement. ANGLE ON a PALE FIGURE standing across the street. He looks feverish and strung-out, in serious need of a fix. This is JARED NOMAK, 20s. He starts towards the clinic. INT. COMMUNITY BLOOD BANK - ENTRANCE - NIGHT Potential DONORS sit in a waiting area, filling out forms, leafing through informational material. A sign in the window reads: "Se habla Espanol". Others read: "YOU ARE MAKING A DIFFERENCE", "GIVE LIFE", and "BECOME A PLATELET DONOR". We overhear a bored-looking EMPLOYEE behind the information desk quizzing someone over the phone: EMPLOYEE Have you recently visited a tropical country? Uh-huh? In the past twelve months have you gotten a tattoo, non sterile acupuncture, or undergone any ear, skin or body piercing? We MOVE PAST the employee to Nomak, waiting. NURSE (O.S.) Jared Nomak? Nomak looks up. We get a better look at his face now - he has a thin scar running from his lower lip down his chin. A childhood accident, perhaps. A NURSE smiles and motions for him to join her. She's carrying a clipboard. NURSE (CONT'D) Hi. We're ready for you now. INT. COMMUNITY BLOOD BANK - HALLWAY - NIGHT Nomak follows the Nurse into a dimly-lit hallway. We track their progress in a convex safety mirror suspended from the hallway ceiling as they pass all manner of medical supplies -- centrifuges, an apheresis device, etc. NURSE (referring to her clipboard) I see from your questionnaire that you don't have any immediate next of kin? NOMAK Not that I'm in contact with. NURSE Nobody to call in case of an emergency? NOMAK No -- (apprehensive) Does that mean I can't be a donor? NURSE It depends. We came up with some unusual results on your blood test. Nomak follows the Nurse to a steel door were TWO SECURITY GUARDS await them. Both look bored, paying little attention to the monitor which offers a view of the examining room beyond. There is also a small window with safety glass. GUARD #1 opens the door, following Nomak and the Nurse inside. GUARD #2 remains behind, manning the hallway. INT. COMMUNITY BLOOD BANK - EXAMINING ROOM - NIGHT The Nurse ushers Nomak into the room, indicating he should sit in a kind of reclining dental chair with arm and headrests. Nomak notices a security camera mounted above. NOMAK (anxious) How unusual? Beat. The Nurse sets aside Nomak's file, looking uncomfortable. NURSE Your blood has a very rare phenotype, one that's quite valuable to people like us. NOMAK Us? What are you talking about? A kind-faced DOCTOR enters, nodding to Guard #1. DOCTOR It's a good news-bad news scenario, Jared. Good news for us, bad for you. The Doctor and Nurse smile, BARING FANGS. We realize now that they are both vampires. The Guard, too. He grips Nomak by the throat, forcing him back into the restraint chair. As the vampire Guard does so, his hand brushes against Nomak's jaw. The flesh on Nomak's chin briefly separates along the scar - almost as if it were a seam. The guard pauses - and Nomak LAUGHS. Definitely NOT the reaction the vampires were expecting from a potential victim. Nomak starts to shake and twitch, like he's going into some kind of seizure. The whites of his eyes bleed red. He throws his head back, opening his mouth as a PAIR OF RAZOR SHARP CANINES extrude from his gums. These are longer, much more lethal-looking than the fangs of the vampires and -- Nomak lashes out, knocking the Guard backwards. The Nurse SCREAMS. Nomak clamps his mouth onto her throat, SLAMMING her back against the wall. The vampire Doctor rushes to the door, scrambling to unbolt it. Nomak reaches for him, HOWLING with blood-drunk laughter as he lifts the Doctor up. Nomak flings the Doctor about like a toy, using his body to SMASH the lights, then the security camera above. INT. COMMUNITY BLOOD BANK - HALLWAY - NIGHT We hear SCREAMS and HORRIBLE NOISES coming from the examining room. Guard #2 draws a gun and looks to the security monitor with alarm. The screen goes black. He looks to the small window, trying to peer into the now-darkened room beyond -- SPLASH! A wave of blood smears across a window. A HAND wipes a patch of blood away, revealing Nomak's baleful, distorted eyes. Guard #2 starts to back away when -- BANG! Nomak slams against the other side of the steel door. BANG!BANG!BANG! The door begins to bend, hand-shaped impressions bulging outward as Nomak starts to peel the door apart like it was an aluminum can. Guard #2 has seen enough. He turns and runs even as the door CAVES INWARD off its hinges. Forward momentum sends the door sliding across the hallway floor where it trips up the Guard. ON THE DOORWAY as Nomak steps into the hallway. Because of the lights above, there are alternating pools of light and shadow in the hall. Nomak advances towards us, his face coming in and out of darkness. NOMAK Vampires -- With each pool of light, his awful smile seems to distort further and further, until his mouth seems to be widening all the way back to his ears. NOMAK (CONT'D) I fucking hate vampires. On the floor, the vampire Guard CRIES OUT in fear, helplessly raising his hands to defend himself. Nomak HOWLS and leaps towards him/us, blacking out the screen with his hurtling form as we --
