Captain America: Reborn is a six-issue (originally intended to be five issues monthly comic book limited series published by Marvel Comics between July 2009 and January 2010. Written by Ed Brubaker, and illustrated by Bryan Hitch with inking by Butch Guice, the series promises to reveal the "truth" regarding the death of original Captain America Steve Rogers, returning him to life.
The series was announced April 2009, with the title of "Reborn". More information was released on June 15, 2009, two days before the release of Captain America #600 (which serves as the prelude to the limited series). That article revealed the complete title of "Captain America: Reborn", and that Ed Brubaker, Bryan Hitch, and Butch Guice will be involved with the series. A trailer of the new series was placed on the Marvel website.
As "Bucky Cap" reflects on what's happening to the country, Rikki Barnes talks with Eli Bradley (aka Patriot), telling him that she wants to be Bucky's new partner. Patriot says that Bucky is not looking for a new partner right now, but he wants Rikki to meet him, like Steve would have wanted him to. Meanwhile, Crossbones and Sin escape from a H.A.M.M.E.R. holding facility in Colorado, and the Red Skull returns, still trapped in his robot body. In Central Park, Falcon, Natasha, Bucky, Luke Cage, Jessica Drew, and Clint Barton are there without their costumes, but have a teleportation spell ready in case Norman Osborn and his Dark Avengers attempt to capture them. Osborn, Sentry and the new Ms. Marvel manage to find the group while hovering over the park, but Osborn decides not to attack them. Instead, Osborn appears in front of the crowd, and says that the gathering, thought to be illegal, was approved by H.A.M.M.E.R. He declares that they will honor Captain America for who he was, and the crowd shouts his name, which upsets the Avengers present. Sharon Carter then appears to them, saying that there is still a way to save Steve.
At the H.A.M.M.E.R. holding facility in Colorado, Sin is questioned about a second shooter besides Crossbones in the murder of Captain America. They promise her freedom in exchange for the shooter, figuring that since the Red Skull is dead, she does not need to be loyal to him anymore. Sin laughs at this, and tackles the H.A.M.M.E.R agent, whispering something in his ear. She is about to escape when Bullseye captures her. Later, Bullseye and Norman Osborn are talking with the agent Sin attacked, and he says that she whispered "Why are you sure he is dead?". Osborn declares that is a problem, but the question is whether she was talking about her father, or about Captain America.
Sharon, Falcon, Vision, and Hank Pym are meeting together at Hank's lab. While Bucky and Black Widow infiltrate a H.A.M.M.E.R. helicarrier, Sharon explains to everyone how she shot Captain America. However, when they examine the gun, which she recovered in Captain America #600, they discover that it is technology sponsored by none other than Doctor Doom. The gun didn't kill Steve, but as Zola explains to Osborn during a meeting, "froze him within space and time", and while Sharon was captured by Red Skull, she was used as part of a device to bring Steve back, or "unstick" him from time. When she damaged the machine, Steve did become "unstuck," however, no one is sure where. As Bucky and Widow are attacked by Ares and Venom, there are flashbacks to Steve Rogers, who appears on D-Day, his mother's death, and then back in D-Day with Bucky from that time. He questions what is happening to him, but appears to prepare to go along with where he is, and fight the battles of World War II all over again.
Norman Osborn approaches Sin and Crossbones for a mission. Captain America then ends up in the point of time where he is subjected to the Super Soldier serum by Dr. Abraham Erskine. Meanwhile, Bucky and Black Widow have been apprehended by H.A.M.M.E.R. Agents. Norman Osborn then advises Black Widow to seek out Sharon Carter and order her to turn herself in before the current Captain America is also killed.
Captain America is now in the event in his life where the Inuit have found his frozen body and then flashes toward the Kree-Skrull War event where he is able to briefly talk with the Vision, giving him a message that he is to subsequently forget until the right time. Back in the present, Bucky is freed by Ant-Man and then rescued by Falcon who fights Ghost. However, Sharon has turned herself in. Meanwhile, Sin and Crossbones locate the Red Skull and take him to Latveria so that he could be given a living body.
When Red Skull arrives in Latveria with Sin and Crossbones, Arnim Zola has created a machine that will bring Captain America back. Captain America is now in the point in time where he and Rick Jones (under his Bucky alias) are fighting HYDRA. Back in the present, Norman Osborn holds a press conference about Sharon's surrender as it is watched on the airplane where Victoria Hand has Sharon. At the Infinite Avengers Mansion, Mister Fantastic reveals to Henry Pym that the gun used to shoot Captain America used tachyon particles and the unidentified nano-particles in her blood are linked. He also theorizes that Captain America's body is somehow out-of-sync with their reality, which is why Sharon is the key to bringing him back. The Vision interrupts them, Reed's comment having activated a secret message in his deep storage memory banks from Captain America himself. Ronin, Black Widow, and Bucky attack H.A.M.M.E.R. Mobile Data Collector demanding the whereabouts of Sharon. Once Vision shows the message to the two scientists, Mister Fantastic deduces that when Sharon destroyed the Skull's machine, it caused Rogers to be lost in time. Sharon is brought into Latveria and hooked up to the machine that she previously destroyed where she will be hooked up to that machine alongside the Red Skull. In 1945 at the English Channel Islands, Captain America and Bucky attempt to stop the Nazis and Baron Heinrich Zemo from moving the drone plane armed with an explosive. Captain America realizes that this is the same event at which they both get frozen and his sidekick becomes the Winter Soldier. Then suddenly, he is pulled through his entire life before the Red Skull comes on top of him. By then, his physical form is brought back to its proper reality. However, it is not Steve Rogers who is in control, but the Red Skull.
As Steve watches on from the rooftop, Bucky and Natasha confront Mister Hyde and other prisoners who had escaped from the Raft prison in the morning. As Hyde is about to escape, Bucky spots Steve and throws the shield to him. Steve leaps from the building, grabs the shield, and dives into Hyde. Steve offers the shield back to Bucky who declines. The two then take a stroll along the East River, where they discuss who will continue on as Captain America. Steve expresses that he wants Bucky to continue on as Captain America, even though Bucky explains he does not want it. Steve holds out the shield and asks Bucky to "do it for [him]". Back in the loft Steve explains to Sharon that he couldn't tell Bucky the real reasons for letting him carry on as Captain America. After reliving not only the past but the future as well, Steve feared Bucky would die if he did not continue on as Captain America, even if Steve had to sacrifice the future that he wanted. Steve then visits the White House where he meets the President (although the president's name is not addressed and his face is never shown, the papers are signed 'Barack Obama' with his right hand; Obama in reality is left handed) where he is granted a presidential pardon for the events of the Superhuman Registration Act. He then explains to the president that he is not ready to carry the shield, to which the president accepts but states that he has a feeling shortly "this country's going to need to call on you for something much bigger...".
