The upcoming 
Blade movie will make vampires a big part of the MCU going forward, and the movie’s potential biggest plot hole can be easily explained. Mahershala Ali made his off-screen MCU debut as Blade in the post-credits scene of Marvel’s 
Eternals. While the scene only hinted at the more supernatural side of the MCU, Blade’s solo movie will no doubt put vampires front and center, which raises the plot hole of why they’ve been largely missing from the MCU thus far.,While no vampires have been seen in the MCU yet (with
Morbius, of course, being set in Sony’s Spider-Man Universe), there have been blink-and-you’ll-miss-them references prior to Blade’s debut. In 
Thor: Ragnorok Korg jokes that a large wooden fork was ”
not really useful unless you’re fighting off three vampires that are huddled together.”
Loki also acknowledged the existence of vampires, and that they’re potentially just as powerful and dangerous as the Kree and Titans. Phase 4 of the MCU is embracing its darker side with 
Moon Knight,
Doctor Strange in the Multiverse of Madness, and the upcoming Halloween special 
Werewolf By Night, and Blade’s vampire-hunting will continue Marvel’s foray into horror.,Related: Who Is Blade? Mahershala Ali’s MCU Vampire Explained,Blade‘s potential plot hole is that if the MCU’s vampires have been around for a while and are so dangerous and powerful, why haven’t they shown up yet? The most straightforward explanation is that Blade is very good at keeping the vampires in check. While he’s only one (half) man, he’s so powerful and efficient at his job that the vampires haven’t escalated into an Avengers-level threat. While vampires may be powerful creatures, Blade is even more powerful. In addition to Blade having the vampire’s super strength, agility, and healing powers (as well as being a talented warrior), he’s immune to their bites and can be exposed to sunlight. The average vampire isn’t going to stand a chance against Blade. If Nick Fury or S.H.I.E.L.D. are aware of Blade’s effective nighttime activities, there is no need to get involved.,Another way the plot hole of the missing vampires can be explained is through S.H.I.E.L.D. covering Blade’s tracks. With all that the people of Earth have been through in the MCU over the past decade (Hydra, Ultron, Thanos, Titans), S.H.I.E.L.D. might well have taken the decision to keep the existence of Blade and vampires on a need-to-know basis. The more people that know about Blade increases the risk of the secret coming out. There is no sense in creating potential mass hysteria when the world is still healing from its previous battles.,Given how powerful the MCU is setting Blade up to be, the corresponding threat needs to increase in order to create a compelling narrative for 
Blade. This could spell the end of vampires hiding in the shadows and bring them and Blade to the world’s attention. After all, Blade chose to make himself known to Dane Whitman at the end of 
Eternals. As he’s usually a loner, revealing himself now indicates the MCU vampire threat is increasing beyond his capabilities. While few people in the MCU have been aware of vampires previously, the events of 
Blade will likely change that indefinitely.,Next: What If Blade Was In Endgame? Could He Beat Thanos?
