History

The New Captain America

Several months after the "Blip," and with the whereabouts of Steve Rogers still unknown to the public, the United States government appointed John Walker as the new Captain America.

John as Captain America

Walker went on tour for the government as the new "Cap," attracting the ire of both of Rogers' former allies and comrades, Sam Wilson and Bucky Barnes, the former of whom had been bequeathed Rogers' shield and legacy by the original Captain America himself. Walker humbly claimed that he was honored to take up the Captain America mantle, being just a normal guy who wanted to do good, though he was actually a highly decorated soldier who had completed several special ops missions for the U.S. Army and had undergone grueling training to become the new Captain America.

Investigating the Flag Smashers

Walker was deployed as Captain America soon after to stop an illegal medical supplies shipment by the Flag Smashers radical group, who were also incidentally being confronted by Wilson and Barnes at the same time. Wilson and Barnes were being overwhelmed by the group, when Walker, alongside his teammate and friend Lemar Hoskins, aka Battlestar, aided them. With his shield, Walker was able to hold his own, but with Bucky and Sam knocked off the shipping truck, and having to use his shield to save Lemar who was also kicked off the moving truck. Walker was easily out match by the super-soldier serum-enhanced radicals' leader, Karli Morgenthau, and was kicked from the truck they were fighting on. He attempted to make amends with Wilson and Barnes later, but they rebuffed his attempt. When Barnes was later arrested for missing a court-mandated therapy session, Walker helped get him out and facilitated a way for Wilson and Barnes to be able to work together without having to go to the therapy sessions anymore. After this, he attempted once more to reconcile with the two heroes, but they advised him that they were free agents and intended to act like it, investigating the Flag Smashers without government oversight. Feeling scorned, Walker told the men he understood, but warned them to stay out of his way going forward.

Walker, with Battlestar, and the GRC, later confronted a Flag Smasher sympathizer who had been harboring the radicals, but he was mocked, scoffed at, and even spat on by the sympathizer, who told him that he didn't care who Walker was because Walker had no political or ideological influence over him, unlike the old Captain America. Infuriated by this act of disrespect, Walker used every ounce of his willpower to refrain from further harming the man and angrily told Hoskins that they would have to find an off-the-books way of managing the Flag Smashers if they were to stop them, because the government guidelines were too restrictive. Walker cited the actions of Wilson and Barnes, who were freely tracking the production of the new and improved super-soldier serum with the help of international criminal and terrorist Baron Zemo as proof, and disgustedly walked away from the interrogation.

Walker managed to track down Barnes and Wilson in Latvia where they were continuing to work with Zemo to find the Flag Smashers and the vials of super-soldier serum they still held in their possession. Walker confronted the trio, who had just gotten a tip-off from a local child as to where Karli Morgenthau would be. Walker, Hoskins, Wilson, Barnes, and Zemo all moved on this location, but Wilson insisted on having some time to talk to Morgenthau alone. Walker granted him ten minutes, but became increasingly anxious and paranoid when Wilson didn't return. Walker attempted to charge in before the ten minutes was up, but was stopped by Barnes, who Walker taunted, saying that everything was easier with the super-soldier serum. Walker then asked Barnes if he was okay having Wilson's blood on his hands if something went south, convincing him to let Walker pass. Walker burst through the doors of the room where Wilson was still talking pacifistically with Morgenthau, frightening the Flag Smasher and causing her to flee with the super-soldier serum. Meanwhile, an enraged Wilson ran off to find her.

Walker later came across Zemo, who was destroying the remaining vials of serum by stomping on them. Walker threw his shield at Zemo's head, knocking him unconscious. Though most of the vials had been destroyed and Morgenthau had gotten away, Walker managed to find and pocket a single remaining vial of serum before Hoskins, Wilson, and Barnes showed up. Walker later confronted Barnes and Wilson again, demanding they turn over Zemo into his custody. The two refused, with Barnes already having promised to turn the baron over to the Dora Milaje, who promptly revealed themselves, after an attempt to kill John via a thrown spear to the head, to collect Zemo. Walker and Hoskins engaged the two, being quickly and efficiently beaten into submission while Wilson and Barnes initially watched, mocking him all the while, before also engaging after deciding that they needed Zemo for a little while longer. After the four were summarily beaten, all six present discovered that Zemo had used the commotion to escape into the sewers. As the Dora Milaje left, Walker lamented that they weren't even super-soldiers and he still couldn't beat them.

Fall of a Hero

Walker and Battlestar

Walker had a discussion with Hoskins soon after regarding the nature of the serum and whether or not he would take it. When Hoskins said he would take it in a heartbeat, Walker asked him if Hoskins thought Walker would be deserving of it, to which Hoskins replied that it simply amplified what was already there, and pointed out Walker's bravery during a brutal mission which had earned him his decorated status as a soldier. Hoskins went on to remark how many more people they could have saved on that mission if they had been enhanced by the serum, and Walker agreed. Sometime later, Walker injected himself with the serum he had kept, enhancing his strength and agility, among other physical abilities, but also seemingly making himself more mentally unstable. Walker tracked down Morgenthau, who was once again having a discussion with Wilson and Barnes alone, as well as the rest of the Flag Smashers, and charged in to subdue them. Hoskins was quickly kidnapped, however, and Walker ran into an angered Wilson and Barnes while trying to find him. The three came into conflict with the rest of the Flag Smashers, including Morgenthau, who attempted to assassinate Walker. Hoskins managed to escape just in time to prevent Karli from fatally stabbing Walker. Karli retaliated by punching Hoskins, the force of the blow sending him into a brick pillar, killing Battlestar. This gave pause to everyone in the room, during which time the Flag Smashers made an escape and Walker tried unsuccessfully to revive his teammate. After confirming his death, Walker was blinded by rage and executed one of the Flag Smashers with Captain America's Shield out on the street with many onlookers capturing it on their phones.

After killing a man with the shield

Walker fled the scene, shocked by what he did, but was confronted by Sam and Bucky soon after in a warehouse. They attempted to persuade Walker to turn himself in peacefully, with Walker being compliant until they demanded the shield from him, making it clear this was the only reason they came. Walker declined, telling them they didn't want to do this. But Bucky confirmed they did, and the three engaged in an intense fight, which saw Bucky try to kill Walker twice before being incapacitated temporarily and tearing Sam's wings off, effectively destroying his wing-pack. He prepared to kill Sam with the shield in the same way that he had killed the Flag-Smasher, but was stopped by Bucky. The two pinned Walker against a metal support column and tried again to get him to relinquish the shield, but when he refused, they broke his left arm, took it from him and left him for dead in the warehouse. He was afterwards placed on trial and received an 'Other Than Honorable' discharge from the military, retaining none of his status or benefits and only avoiding a court-martial due to his previous valiant service to the country. Shortly after the sentencing, Contessa Valentina Allegra de Fontaine approached him, telling him that he was of interest to many powerful people and indirectly offered him a job, telling him to pick up when she called. Later on, Walker visited Hoskins' family, to spare their feeling he told them that he had killed the man who had killed Hoskins, when in reality the Flag Smasher he had killed, though involved, was just an accomplice. He vowed to track down the rest of them and returned home. Here, determined to still be Captain America, he started forging a new shield of his own using his medals, including welding his Medal of Honor into the shield's inner surface.

Walker later confronted Morgenthau and her fellow Flag Smashers when they led an assault on the GRC headquarters in New York City, telling her he intended to finish what they'd started. However, despite initially having the upper hand, their numbers were too many and he was quickly taken off his feet. As he used his homemade shield to defend the onslaught, it did not hold up nearly as well as the Vibranium one in battle. Walker would receive assistance from Bucky, who, along with Wilson, now Captain America, was already engaged in combat with the Flag Smashers. Walker continued to fight and was able to finally get Morgenthau one-on-one. But when she put the armored truck full of GRC politicians in danger. Walker was confronted with the choice to save the GRC politicians in imminent danger of falling to their deaths or to pursue a fleeing Morgenthau. He chose to save the truck, and as he started to pull it to safety, Morgenthau and the remaining Flag Smashers attacked him. Being forced to let go of the truck and fall. He and Bucky watched as Wilson, utilizing his new jetpack, pushed the truck back from the ledge, saving the GRC politicians. Walker then went to hunt down the remaining Flag Smashers with the two Avengers, whereupon Wilson directed him and Barnes to search in one direction while he went another way. Walker and Barnes soon discovered that he had sent them off Morgenthau's trail, hoping to try and talk to her once more, though this also failed when Sharon Carter killed her instead.

Walker was later called upon by Valentina Allegra de Fontaine as she promised, where she gave him a new and updated suit with a black, red, and white theme, and told him that the world already had a Captain America, and that what they needed now was a U.S. Agent.

Meeting His Assignment

As U.S. Agent, He would be tricked by Valentina into going into a booby-trapped building by believing he was sent in to stop a "thief" with deadly force.. He would assumingly almost succeed in his mission though would be stopped by Taskmaster, who was sent to kill him also by Val though Walker also beat Taskmaster in a fight though as he tries to go after both Taskmaster and Yelena, he is once again stopped by the appearance of a third person, Ghost, who was sent to kill Taskmaster. Walker attempted to kill Yelena, pinning her down on her back and trying to stab her with a knife to her head. As they both struggle for her life, Taskmaster approaches the two without their knowledge but is intercepted by Ghost and is shot in the head, killing Taskmaster, to the surprise of Walker and Yelena. Right after Taskmaster's death, Walker is kicked off of Yelena after the three hear a fifth person, a dazed man named Bob. Yelena comes to the realization that Valentina sent all of them after each other so that they could kill each other as they were O.X.E. evidence that needed to be destroyed. Walker rejected this theory as Ghost, Taskmaster, and Yelena were "cheap mercenaries" compared to him and that he wasn't going to fail the mission as if he completed the mission, Valentina claimed he'd have a "clean slate guarantee." After Ghost tried to leave the trap building, a sound barrier played, stopping any of them from leaving. Instead of leaving, Ghost and Walker looted Taskmaster's body for weapons and equipment though the building suddenly turns red and begins heating up, with Walker finally coming to terms that he and all the others in the were sent to their deaths. Eventually, the remaining four discover the sound barrier control panel and destroyed it, allowing Ghost to escape and open the door for the others at the last possible second. Walker began working along the few and became aggressive towards Bob. Walker Broke a hole in the wall to the building's elevator shaft, leaving the four stuck below it. Though Walker failed to jump to the top of the shaft, Bob came up with the solution of all four going back-to-back and climbing up to the top. When it became clear they had no way to actually exit without risking a fall to their immediate death, Walker came up the idea to spin the few up to the top which nearly killed all four of them though his idea worked, allowing Walker to pull the three up to safety. As Walker tried to pull up Bob, he is sent into a memory where, in the aftermath of being dishonorably discharged from Captain America, he was neglecting his child and being a poor husband to his wife. After fighting some armed men with his new "team", the four escape after Bob made a distraction that seemingly lead to Bob being shot to death.

As Walker drove away with Yelena and Ghost, they notice Bob flying in the clouds before falling back to Earth, the impact causing the vehicle to flip over and down a slope. Walker is shown stolen papers from Yelena about Project Sentry where he revealed what little he knew about the project before giving Yelena and Ghost some food as they walked aimlessly through the desert. As the three walked in the desert, they spotted a red truck that calls out to Yelena, turning out to be Alexei Shostakov who they hitched a ride with. Walker suggested for all of them to split up though Alexei suggested the four of them form a team. Walker spotted a convoy coming after them that shot at them, with Walker using his shield to block the firing artillery until the convoy was taken out Bucky Barnes, who after defeating the convoy, used an explosive to flip the vehicle of Alexei.

The Thunderbolts

Bucky took in all four and tied them up as he interviewed them and learns of Bob/Sentry from them and Mel on the phone. Bucky untied the four and convinced Walker and the other three to become a team to stop Valentina and save Bob. Bucky drove them into the Watchtower (Formerly the Stark Tower) as they fought armed men before going up the tower and speaking to Valentina. Valentina sized up the team, causing Walker to almost shoot Valentina though they instead decided to take Valentina into custody. They were stopped by Bob, now the Sentry, who Valentina told to take out the rogue agents. They quickly lost the battle with Walker's shield being bent out of shape, his gun being melted, and his right hand being burned from said melting gun. Walker and the "Thunderbolts" left the Watchtower where they questioned their status as a team with Walker briefly splitting away from the others until a malicious version of The Sentry called the Void began causing destruction to the city, nearly crushing and killing a woman before Walker and his team worked together to save the woman, to the watchful eye and applause of the city. The Dark Sentry began causing a darkness to slowly consume the city, including Yelena who stepped into the darkness in an attempt to stop Bob. Walker, Ava, Alexei, and Bucky decided to go into the darkness, finding Bob and Yelena being attacked by the environment of the room. Walker along with the others, helped Bob through his rooms molded after his worse memories where they come face to face with the Dark Sentry, known as "The Void". Walker tried to motivate Bob to fight The Void but after they realized Bob fighting the void would just cause it to overtake him, Walker broke free of his binds and embraced Bob along with the other Thunderbolts, defeating The Void and returning them to the real world, which was freed from The Void's veil of darkness.

Walker complimented Bob on his performance of beating The Void though Bob had no memory of the entire recent events. Bob worried on what would happen when he regained his memory, causing Yelena to bring Bob along with them to attack Valentina in revenge for everything she had done but Valentina, once again, pulled them into a trap. The Thunderbolts found themselves surrounded with the press, as Valentina swears them all as The New Avengers.

New Avengers v. Space Crisis

Fourteen months later, Walker, still with his bent shield, along with his team discussed legal trouble with Captain America for use of the copyrighted name, Avengers. Walker, due to Yelena, learnt of a "space crisis" that despite being The New Avengers, a title that people dispute on as Walker has seen due to harsh "memes" about said topic, they have not been properly informed about. Yelena ran a satellite image that detected an extradimensional spacecraft with a giant number 4 on it entering Earth's atmosphere. Walker commented on the spacecraft being a "cool ship" as the team looked on to the image of the ship, confused on what would happen next.

Attributes

Powers

Artificially Enhanced Physiology: Walker dosed himself with a new version of the super-soldier serum developed in Madripoor by Dr. Wilfred Nagel which grants the user all the same abilities as the original serum taken by the likes of Steve Rogers and Bucky Barnes, but without significantly enhancing or changing the user's appearance and physiology. Walker also demonstrated a heightened awareness of his surroundings, being able to narrowly dodge a knife thrown at his neck from well outside his range of view.

• Enhanced Healing Factor: Walker can heal at a much faster rate than a normal human. After his fight against Falcon and Bucky where his arm was broken, he recovered from his injuries in a few days.
• Enhanced Strength: Walker demonstrated the ability to throw his shield so hard that it embedded itself deeply within a concrete wall, as well as throwing a man down the stairs effortlessly. Walker later used his strength to quickly and brutally beat a man to death with the edge of the shield.
• Enhanced Durability: Walker was able to withstand several blows from other enhanced individuals without it fazing him in any meaningful way. He was also able to jump out a window and land on a car, crushing it, without taking any kind of damage.
• Enhanced Speed: While chasing a man who was also enhanced with the same super-soldier serum Walker took, Walker was able to catch up with seemingly little effort, despite his target running far faster than any normal human being.
• Enhanced Agility: Walker demonstrated the ability to react exceptionally quickly to his surroundings, parrying many attacks from other enhanced individuals and dodging a thrown knife with ease, despite not being able to see it until right before it almost hit him.
• Enhanced Stamina: Walker was able to keep up with a brutal fight against several other serum-enhanced individuals before beating several more, jumping out a window, chasing down another man, and beating him to death, all seemingly without expending any stamina.
