The latest MCU movie is finally here as Phase 4 continues
After over a year of delays, Black Widow is finally here--and it's the first MCU movie released directly on Disney+ so you can watch from the comfort of your own home.
1. Yelena Belova
While the MCU may have invented Yelena's backstory as an Ohioan raised by two super spies and her adoptive big sister Natasha, she's still a character from Marvel Comics--and, unsurprisingly, a Black Widow agent.
2. Sokovia accords
Our good friend, the Sokovia Accords, keep coming up--and it's no wonder. Given where this movie is set in the MCU timeline, this is the most pressing issue right now. I bet Ross and his team feel pretty silly being worried about this once Thanos rolls into town.
3. King of Wakanda
This is a bit of a two-for-one reference--the king Natasha literally fought was of course T'Challa, but lets not forget that Civil War kicked off with the assassination of a different Wakandan king, T'Challa's father, T'Chaka.
5. Moonraker and box dye
While Natasha is in hiding, she spends her time watching old James Bond movies--Moonraker in this specific case--and contemplating dying her hair. We know she ultimately goes through with this, thanks to her blonde look in Infinity War.
6. Budapest
The frequently referenced Budapest incident is a focal point in this movie--at least we finally know what Natasha and Clint have been offhandedly quipping about since Avengers.
7. Dreykov
Dreykov isn't actually a character in Marvel comics, but he was mentioned in the MCU prior to this movie--by Loki, in fact, back in The Avengers. Attempting to intimidate Natasha, Loki brings up, specifically, "Dreykov's daughter," who we learn more about here.

Species of the Black Widow Spider

Black Widow Spiders from Around the World

A healthy, adult female is capable of laying around three or even more egg sacs every year. A sac can contain anything between 40 and 100 eggs. The mother spider keeps guarding its eggs for many hours, or even several days at a stretch until they begin changing color and the time for them to hatch nears.
Spiderlings
Unlike the true black widow spiders, the baby false black widows have a dark coloration similar to their mothers when they emerge from the eggs. The mother guards the young ones until they are matured enough to separate.
How Poisonous is the False Black Widow Spider Bite
