Steve Rogers, Bucky Barnes and Addie Robins. The three grew up together in Brooklyn, becoming close friends quickly. Addie and Bucky often ended up saving Steve's scrawny behind from bullies over the course of their lives, and while he was grateful for it, a small part of him resented them for it. That resentment only grew when in 1942, the three agreed to join the army together. Steve was classed as 4F, unfit for service. Bucky got in easily. Even Addie had gotten into the Women's Army Auxiliary Corps with ease. The scrawny man never gave up, eventually making his way into the army and then going on to become the famous Captain America. After losing both Bucky and Addie in the war, Steve was frozen for seventy odd years. After the formation of the Avengers, while searching for Loki's sceptre, Fury brings on an army consultant, someone particularly skilled in finding things that aren't meant to be found. That someone was Addie Robins. Disclaimer- all pre existing plot lines and characters belong to Marvel, I only own Addie and her plot lines
