In the hands of Stan Lee, Don Heck, and Don Rico, Marvel Comics debuted an unlikely alliance between a Russian spy and a master archer in 1964's run of Tales of Suspense. The pair grew close through their affinity, allowing them to develop one of Marvel's longest lasting friendships, as well as one of their longest running star-crossed romances.

While the Marvel Cinematic Universe's approach to their relationship threw fans for a loop when Avengers: Age of Ultron deemed the two non-romantic, Natasha Romanoff (Scarlett Johansson) and Clint Barton's (Jeremy Renner) unbreakable bond undoubtedly draws ties to that of its source material. From the call that spared Natasha's life to the one that saved Clint's, the former spies turned non-powered Avengers have a connection cemented in both similarity and history – a feat that makes them one of the strongest dynamics within the saga of superhero films.

Still Friends

Clint Barton and Natasha Romanoff Fight During Captain America: Civil War

The moment is a mere seventeen seconds, but Clint and Natasha's scuffle in Captain America: Civil War remains one of the most relevant onscreen depictions of their dynamic.

Pitted against each other, the pair of master assassins are forced to fight during the film's airport battle. But it's when Wanda (Elizabeth Olsen) throws a quipped "You were pulling your punches" that the nature of their spar admits a silent truth. Unlike their avenging teammates, the connection between Black Widow and Hawkeye transcends disagreement, and the two are incapable of truly doing any harm to one another.

Budapest

Flashback to Natasha Romanoff in Budapest in Black Widow

Though Budapest began as a throwaway line in The Avengers, it quickly spiraled into the untold story of Natasha and Clint's history with a deleted mention during Captain America: The Winter Soldier and a second shared joke on the Benatar in Avengers: Endgame. Yet despite multiple acknowledgements, it's only in 2021's Black Widow that the reference is given slightly more backing.

When Natasha finds Yelena (Florence Pugh) in a safe-house in the Hungarian city, it becomes clear that both she and Clint have been there before, but it isn't until the two women are holed up in the ventilation system of an underground train station that this truth is confirmed. Their mission in Budapest was the final step in Natasha's defection to SHIELD, and after a firefight with local law enforcement, they spent ten days in hiding – two of which were in the very same air duct.

Tokyo

Hawkeye and Black Widow Hold Hands in Avengers: Endgame

When Thanos (Josh Brolin) snapped, the world fell apart. Clint fell apart, and in the moments that left her feeling responsible, so did Natasha. But when Ant-Man (Paul Rudd) turns up five years after the fact, the promise to restore what had been taken becomes a tangible reality.

To no one's surprise, Natasha's priority amidst this Endgame discovery is to save Clint from himself. By tracking the vigilante lifestyle that he has succumbed to, she finds him on the streets of Tokyo, and in one heart-wrenching moment, makes a different call of her own. Taking her partner by the hand, Natasha returns to Clint a promise that he made to her the day they met.

Grounding

While themes like Budapest have been recurring pieces of Black Widow and Hawkeye's story, the MCU has also made a habit of paralleling moments between the two, even with something as simple as touch.

It's tangibility in times that Natasha or Clint are left reeling from bouts of mind control or time travel that demonstrate their reliance on each other, using the familiarity of touch to ground the other back to reality in a way that few would think to.

Cognitive Recalibration

Black Widow and Hawkeye Fight in The Avengers

While 2012's The Avengers formally introduced the partnership between SHIELD master assassins Black Widow and Hawkeye, it also illustrated the intensity of their relationship. In the film, Clint is swayed by Loki's (Tom Hiddleston) mind-control, and Natasha's primary focus becomes bringing him back – both physically and mentally.

Natasha's priority becomes most prevalent when Director Fury (Samuel L. Jackson) calls for someone to stop Clint, and she jumps into action knowing that anyone else would not spare his life. The two take part in a synchronous brawl choreographed by their portrayers, but it's one last punch to the head as Clint mutters, "Tasha?" in recognition that brings him out of the spell once and for all.

Compromised and Captured

While Natasha's capture in Age of Ultron has been met with much-deserved criticism since the film's 2015 release, it also set up yet another seamless parallel laid against Coulson's (Clark Gregg) infamous "Barton's been compromised" phone call at the start of The Avengers.

Both scenes showcase that while Clint and Natasha lack fear regarding their own careers, they do share a fear losing each other and the sole focus of both becomes the safe return of their partner.

'I Need to Talk to You'

Clint Talking to Natasha's Name on the Avengers Plaque in Hawkeye Episode 5

Marvel's Hawkeye is chalked full of moments that explore Clint's grief and guilt over the loss of Natasha, but it's in a moment stood in front of a plaque honoring The Avengers that the audience truly feels how lost he is without her.

Hours before resuming the Ronin moniker that she saved him from, Clint goes to Natasha – or, to the only Natasha that he can seek out – to apologize for his upcoming actions. Turning his hearing aid off so that it's only the two of them, he becomes reminiscent of their past and of Natasha's stubbornness, noting her need to win for "a stupid orange rock". Clint chokes back tears as he tells her he misses her, and there's an implication in his tone that perhaps he believes Natasha's sacrifice wasn't worth her life.

Vormir

Like a double-edged sword, Clint and Natasha's trek up Vormir in Endgame becomes a defining moment in their relationship – serving as a moment to exemplify their biggest loss, as well as their greatest strength. Love.

The cliff-side duel that takes place in attempt to spare the other all but confirms that unlike Thanos' offering, this soul-for-a-soul sacrifice is soul-splitting, as if Hawkeye and Black Widow have always been somewhat of a singular entity. It's only seconds later that this is reaffirmed as Natasha whispers a tearfully permitted "let me go" before kicking free of Clint's grasp; the loss of contact replaced by a feeling of unbalance.

A Different Call

Clint and Natasha Discussing Clint's Different Call in The Avengers and Hawkeye

Long before their days of superhero team-ups, SHIELD marksman Clint Barton was tasked to eliminate an assassin from Soviet-Russia's Red Room program. But face-to-face with Natasha, he notices something different about the infamous Black Widow. She wants an out, and Clint decides to give her one.

This call would later be referred to as the best shot he never took, allowing Natasha to defect to SHIELD with Clint's help. Because of this, the two form a deep trust, and that trust leads to their unwavering bond.

The Infirmary

It's hardly a surprise that The Avengers' infirmary scene would take the top spot. The scene is one of trust and connection between two untrusting spies, and it's clear in their first real moment that they care deeply for one another.

After a mind-control fueled brawl, Clint wakes with Natasha by his side. She saved him, and refuses to let him torture himself over things that cannot be changed, but it's here that he senses something is wrong with her, too. Sat an inch apart, Clint pries just enough to get Natasha to open up, and she admits that she has been compromised.

Honorable Mention: The Arrow Necklace

Natasha Romanoff Wearing the Arrow Necklace in Black Widow

The arrow necklace may not be a "moment", but it is worthy of recognition. Chosen as a nod to Hawkeye by Scarlett Johansson, the pendant has been worn in three of Black Widow's eight appearances.

Serving as a reminder of her most trusted "interpersonal relationship outside of work", the small silver arrow resides on a chain around Natasha's neck during the fall of SHIELD and after the snap in Endgame while Clint is lost and Natasha is seemingly lost without him. But it's in the timeline prior to Endgame that the charm is last seen – worn during Black Widow while Natasha is forced to face the past that the archer spared her from.
