Captain America and Bucky (2011 series) #622

As the war progresses, Captain America and Bucky become part of the Invaders along with the Sub-Mariner, the Human Torch, and Toro. What Bucky does not admit to anyone is how out-of-place he feels on a team of superheroes, a fact the arrogant and angry Sub-Mariner keeps reminding him of. The Invaders are on their way to stop a gang of Atlantean rebels who are aiding the Nazis; Bucky insists on facing the enemy on a beach armed with a pair of pistols but he is quickly disarmed and threatened with death. Namor is forced to allow U-Man to escape to rescue Bucky, which only increases his contempt for the teen sidekick....

On a mission in Poland three weeks later, a trap is sprung which nets all the Invader save for Bucky who was doing recon some distance away. Finding Cap’s abandoned shield, he trails the Nazis to a hidden base in the woods where mad scientist Arnim Zola has the heroes imprisoned in huge glass tubes. His object: to drain their powers into a musclebound test subject to create a superhero for the Third Reich. Bucky rushes in and opens fire on the Ubermensch but the villain uses the Torch’s powers to melt the bullets then Namor and Cap’s speed and agility to leap across the room and overpower Bucky. But being a newborn, the enemy hasn’t yet gained control over his abilities and Bucky manages to free himself with a kick to the face. The Nazi lashes out blindly and immolates two guards. Zola unwisely lets slip that the monster’s powers are only temporary so Bucky hurls Cap’s shield to crack open the glass tubes imprisoning his allies. He then dodges the enemy until Cap arrives to knock him out. Zola and the Ubermensch are taken prisoner and the lab is burned to the ground. Namor grudgingly recognizes Bucky’s limited value and the young hero is pleased with the near-compliment.
