Warning! Spoilers ahead for The Falcon and the Winter Soldier episode 5, "Truth"

In The Falcon and the Winter Soldier episode 5, Sam Wilson returns to visit Isaiah Bradley, who reveals his scars and tragic story as a Super Soldier, darkly mirroring the story of Steve Rogers as he was never allowed to become Captain America himself. In Falcon & Winter Soldier episode 5, "Truth," Sam and Bucky Barnes fought and defeated the new government-approved Captain America, John Walker, after he publicly executed one of the Flag-Smashers in response to the death of his partner Battlestar. This led to Sam getting the shield back.

Now that Sam has the shield in his possession once more, he's looking for answers, with one of the main ones being why things went so wrong for Isaiah Bradley, the US government's second successful attempt at creating a Super Soldier. Living under the radar and out of the public's knowledge, Sam can't understand why no one knows about Bradley or why he had been imprisoned for 30 years.

Now, Isaiah reveals to Sam what really happened to him during the 1950's, and he also reveals the scars he's carried ever since. Additionally, Bradley offers an incredibly strong challenge to Sam, as he believes that the world will never allow a Black man to be Captain America. Furthermore, given everything that happened to Isaiah and the country's history of racism and mistreatment that still persists, he thinks no self-respecting Black man should want to wield the shield either.

Isaiah Bradley's MCU Backstory Explained

In the MCU, it's been revealed that Isaiah Bradley was part of an entire unit of Black men in the 1950s who were essentially used as lab rats during the Korean War. Going out on several missions, Bradley revealed that he was one of the only members of his unit to survive and actually remain stable from the super soldier serum injections they all received. Bradley also had an encounter with the Winter Soldier in 1951, as HYDRA feared Bradley and his power just like they did Steve Rogers. After several troops that were sent in to take Barnes down never came back, the US finally sent in Bradley, and their brawl resulted in half of the Winter Soldier's arm being ripped off in Goyang.

However, Bradley became enraged during Bucky and Sam's first visit to his home in The Falcon and the Winter Soldier episode 2, and one of the last things he revealed was that he was imprisoned for 30 years for being a hero, constantly being experimented on by both the US government and secret HYDRA agents. While Sam was naturally quite shocked by this revelation, Bucky confirms that Steve Rogers never knew about Bradley, feeling as though Isaiah had already been through enough.

As Falcon & The Winter Soldier episode 5 reveals with Sam's second visit to see Isaiah Bradley, his deeper origins are incredibly tragic and heartbreaking. While there's portions that are the same as the comics, there are some key differences and alterations, such as Bradley's wife dying while he was still in prison, and all the letters she had written were kept from him until he managed to break out of his confinement. However, more details and differences of Isaiah Bradley's dark past as a Super Soldier are revealed as well.

According to Bradley, a handful of Black soldiers were given different versions and variants of the Super Soldier Serum, though the soldiers themselves weren't told that they were being given the serum. Instead, they were told that they were getting tetanus shots. Despite many being unstable, they were still sent on missions (such as Bradley's encounter with the Winter Soldier), and several began to die off as the missions went on. Additionally, Bradley reveals that some of these soldiers had been captured and were being held in a POW camp, and he heard that the higher ups were intending to simply blow up the camp in order to hide the evidence of what they had secretly done to all of these men. This prompted Bradley to break out and save all of his captured comrades, though he was eventually the last test subject standing all the same.

How Bradley's Story Was Told In The Comics

Isaiah Bradley's MCU origins tracks rather well with those in the comics (albeit more streamlined). Being selected and experimented on against his will alongside 300 other Black soldiers during WWII, Bradley's entire platoon unwillingly became part of Project Rebirth in its attempts to recreate Super Soldiers like Captain America. However, Bradley was the only one to actually survive the process after the others in his covert ops team died. On his final mission to kill the doctor of Germany's Super Soldier program, Bradley stole one of Captain America's costumes and shields. While he was victorious in his mission, his eventual return resulted in a court-marshal and life imprisonment for stealing the identity of Captain America.

However, he was released 17 years in after his wife convinced the President for a pardon, on the condition that he would swear to a life of secrecy about what had been done to him. While Bradley kept quiet, word about the Black Captain America spread across black communities all over the country, and his name was honored by many of Marvel's Black heroes. Furthermore, his grandson Eli would become a the Young Avenger known as Patriot, having received a blood transfusion from his grandfather to gain the powers and strength of a Super Soldier as well.

Where Isaiah Bradley Got His Scars

Sadly, The Falcon and the Winter Soldier episode 5 reveals that Isaiah Bradley was tortured and imprisoned for his heroic actions, receiving terrible scars as a result. He was then experimented on and had his blood taken for 30 years. However, a nurse took pity on him and declared him dead by altering paperwork, helping him escape and giving him the box filled with his late wife's letters. Since that time, Bradley had remained hidden and buried, his history erased due to the country's racism and apparent refusal to let a Black man be Captain America.

While Falcon & Winter Soldier doesn't reveal exactly how Bradley got his scars, it's clear that they come from his punishment and the experiments at the hands of the U.S. government, rather than on the battlefield. These scars suggest the government did much more than simply take samples of his blood, inflicting greater acts of suffering upon his body, perhaps with knife cuts or even branding. This is his ultimate punishment, and it's one that ties to the "500 years" past Isaiah mentions.

Branding criminals has a long history, especially in relation to slavery and America's Colonial past. While Bradley himself may not have been literally branded in that sense (though it's a little hard to tell either way), this ties his scarring back to that history: he has been branded a criminal, when all he did was serve his country. Falcon & Winter Soldier has explored the scars of America's past and the Super Soldier Program, and through Bradley it paints a horribly vivid, more literal picture of them. Bradley was eventually freed from jail, but he had to pretend to be a dead man; the US could erase his history, but his scars are a reminder that he was never able to truly escape.

Isaiah Bradley's Story Mirrors Steve Rogers'

What makes Isaiah Bradley's MCU origins even worse is how close they mirror those of Steve Rogers. Just like Steve, Bradley was given the Super Soldier Serum, and was driven to be a hero. While he might not have taken a suit and shield like in the comics, he did rescue POWs and bring his allies home, just like Rogers did in Captain America: The First AvengerHowever, while Rogers was given respect, honor, and was treated as hero, truly becoming Captain America in the eyes of the people, Bradley was punished, harmed, and thrown in jail to be experimented on so they could recreate their success...with someone else. Not only that, but they both had lost loves. However, while Captain America would eventually reunite with Peggy at the end of Avengers: EndgameBradley lost his wife for good, though his lost love never needed to be lost in the first place.

While Isaiah Bradley's anger and rage is completely justified, it looks as though Sam Wilson is still going to make his own choices going forward, while still fully acknowledging the complexity of the Captain America mantle and the legacy of the shield he was given. Isaiah's story is one that matches those of the real-life Tuskegee Airmen (also known as the Red-Tailed Angels), whom Bradley specifically mentions in the episode. Despite their heroic efforts, they too had to face hard racism and hate when they came home from war, and Bradley's origins serve as a fictional parallel to the hard truths plaguing the United States' past, as well as its present. Hopefully, the new chapter Sam will create with the shield as the new Captain America will honor the legacy that was erased and forgotten with Isaiah Bradley as The Falcon and the Winter Soldier continues on Disney+.
