- "Don't worry what other people think. You are meant to fight. Stop pretending to be someone that you're not."
- ―Michael Carter's advice to his sister Peggy
- "Michael give it back!"
"Here it is, come on, take it!"
- ―Peggy Carter and Michael Carter
Michael Carter was born to Harrison and Amanda Carter, and in 1921 he gained a younger sister named Margaret "Peggy" Carter. From an early age, Michael saw that his sister had a great thirst for adventure, which he nurtured. The siblings would often play games of make-believe and would play-fight, ignoring the gender rules which their more traditional mother would attempt to enforce on Peggy.
One day, Michael interrupted Peggy while she was pretending to be a knight slaying a dragon; he took her fictional sword and told her to retrieve it. The two played and tussled until their mother stopped the game, yelling at Peggy for not acting as a young lady should.
- "I know you better than anyone else alive, and this isn't what you want."
"What is it you think I want?"
"Same thing you've wanted since you were a little girl, a life of adventure."
- ―Michael and Peggy Carter
In the outbreak of World War II, Michael joined the British Armed Forces while Peggy worked as a code-breaker at Bletchley Park. In 1940, Michael recommended his sister for a position with the Special Operations Executive as he believed she was always meant to be a fighter and this was her chance to live a life of adventure. To his disappointment, Peggy turned down the offer.
Michael attended his sister's engagement party where he was finally introduced to her fiancé Fred Wells. Michael was unimpressed by Wells, who worked at the Home Office. Michael disliked that Wells seemed to have no intention of fighting in the war, and was particularly irritated to learn that it was Wells who convinced Peggy to turn down the S.O.E position. Once Wells left to get more drinks, Michael attempted to convince his sister that the life Wells was offering was not right for her, as she wanted adventure her whole life. Peggy however was insulted and stormed away from Michael.
Returning to Europe to continue fighting on the the front lines, Michael was killed just weeks before Peggy and Wells' wedding. Although his death devastated his sister, it did inspire her to listen to his words and she left Wells and accepted the position at S.O.E, soon becoming an agent with the Strategic Scientific Reserve.
