During the Civil War, Natasha sided with Iron Man's faction, putting a strain on her relationship with Steve. However, she did still care about Steve, even switching sides, allowing them to escape while stalling Black Panther. knowing full well that she was risking her freedom, and her life.
Always looking to make up for her past, Natasha then sided with Iron Man during the Super Hero Civil War. This was despite the fact that many of her friends and allies, notably Captain America, opposed the Superhuman Registration Act.
As the two Avengers' factions fought against each other, Romanoff betrayed Iron Man's team to assist Captain America in finding the one incriminating the Winter Soldier, inherently violating the Sokovia Accords. As a result, the fugitive Romanoff worked with Rick Mason to escape the government for aiding Rogers.
She believed in the Avengers - perhaps more than even Tony Stark or Steve Rogers - but she swiftly realized that the team was tearing itself apart. Black Widow initially chose to register under the Sokovia Accords, and she played a key role in helping Tony Stark track Captain America down at an airport in Germany.
Belova questioned Romanoff on why she never attempted to contact or find her, which Romanoff replied was because she thought Belova was living a normal life and didn't want to see her.
Given that Yelena Belova hasn't been domesticated by the Avengers and has gotten used to a more easy life in the United States, she still seems to favor more brutal methods. While Natasha wasn't averse to taking someone out as needed, Yelena seems to go for lethal methods far more quickly.
After tussling with super best frenemy Kate, Yelena confronts Clint on the Rockefeller Center ice rink. She won't accept that Natasha sacrificed herself rather than Clint killing her but is ultimately convinced when he uses her and Natasha's secret whistle.
The relationship between Bruce Banner and Black Widow was unique to the MCU. While their romance never really took off, it was clear they had feelings for one another, and those feelings made Natasha the only one who could calm down the Hulk - but her MCU lullaby doesn't work at all in the comics.
Eventually, though, Natasha gets the upper hand on Clint for long enough to make her decision final, and go through with it. She leaps off the cliff, sacrificing her life for the Soul Stone.
Since Black Widows are weak to sour, a weapon like a Sour Battle-axe or a Toenail Scimitar upgraded down the sour path would be ideal. Occasionally, the Black Widow will summoning a Black Widowling and eat it.
Way back in TALES OF SUSPENSE #52, Tony met and instantly fell for a Russian woman known initially as Madame Natasha. The pair dated for a brief time until he realized she was actually a spy for the Russian government code-named the Black Widow.
While never explicitly stated in the films leading up to Avengers: Endgame, Natasha Romanoff and Clint Barton have a romantic connection in their relationship, though they couldn't consummate it for various reasons.
Among those developing relationships was a romance between Widow and the Hulk, in which Natasha flirts with Bruce and takes up a role as the only one able to soothe his savage alter-ego. In a now-infamous scene, the two connect through perceived flaws when Natasha reveals her inability to bear children.
Originally Answered: Why does Tony tell Captain in Endgame that when they lost Cap wasn't there while he was there all along fighting in Wakanda? He means that Cap. Wasnt with him united when Stark and Dr. Strange were fighting Thanos on Titan.
Black Widow sadly gave up her life to save others in Avengers: Endgame, and Hawkeye gave even more meaning to her Marvel Cinematic Universe death. In Hawkeye, Clint Barton's holiday plans with his kids get upended when Kate Bishop (Hailee Steinfeld) started wearing his old Ronin outfit while fighting criminals.
Both Natasha and Clint valiantly try to make the ultimate sacrifice while saving the other, but it's Natasha who finally falls to her death. A woman played by Julia Louis-Dreyfus, named Contessa Valentina Allegra de Fontaine (Val for short), shows up.
Marvel finally explained Black Widow sacrificed herself in Avengers: Endgame to save Hawkeye's family and her own chosen family, the Avengers. Hawkeye's guilt over his past actions as Ronin and Natasha's belief in not judging people on their worst mistakes drove their decision to want to sacrifice themselves on Vormir.
The romance between Bruce and Natasha fizzled out after “Age of Ultron,” mainly because Bruce/Hulk went flying into space and teamed up with Chris Hemsworth's Thor in 2017's “Thor: Ragnarok.” MCU fans expected Bruce's return to earth in “Infinity War” and his reunion with Natasha to resurface the fan-favorite storyline ...
Who is the only person that can calm the Hulk down?
The Avengers found that a certain lullaby, typically said by the Black Widow, was able to calm the Hulk and help him revert back to Banner, when the Hulk's strength was no longer needed.
She was afraid of him, especially when he was in his Hulk form. She brought a gun out when she thought he was going to have a major outburst. It was revealed in Age of Ultron, that Bruce and Natasha both had romantic feelings for each other. Since she was in love with Hulk, Natasha was no longer scared by him.
As the two talk, it's revealed that Yelena works for the Contessa, who elected to give the former Widow her next target personally. The target in question is none other than Clint Barton's Hawkeye, and the Contessa identifies him as "the man responsible" for Romanoff's death.
Tracking down and killing Clint Barton aka Hawkeye (Jeremy Renner), who Val falsely tells Yelena is “the man who killed” her sister. It's an unexpected moment — one that sets up a major confrontation between Yelena and Clint to come in a future Marvel film or show (presumably the Hawkeye Disney+ series).
Hawkeye's season finale accomplishes a milestone for Yelena Belova in teaching her the truth of Natasha's death, but it doesn't make up for her wasted appearance in the Disney+ series. Florence Pugh's Yelena made her grand entrance in the MCU with 2021's Black Widow as the titular character's adopted younger sister.
