- For the entire war, I was just a sidekick. Captain America's sidekick, but a sidekick nonetheless. Now, I'm an Avenger. The war is over, but the war on crime has just begun, and we are ready to FIGHT!!!!
- Bucky Barnes
When Bucky Barnes discovered Steve Rogers in his army tent changing from a Captain America costume, he was taken in as a sidekick to keep him quiet. He was trained in combat, and soon became an expert. He went into combat with Cap on all missions, and porved his mettle against many dangerous foes. He was even able to keep Baron Zemo on a plane that he was flying. While Captain America disarmed a bomb, he fought the Baron, and the latter fell into the icy water, killing him. Bucky was now scared that he killed someone, but Cap informed him that it was an accident. He was able to fight many great foes during WWII, but Baron Zemo's son kidnapped him and Captain America, and forced the Captain to watch as he blew Bucky's arm off. He was able to get a replacement, and he continued to fight Hitler and the usual foes alongide the Invaders. When the war was declared over, the Invaders became the Avengers, and Bucky took the name "the Soldier" as a founding member.
