First appearing in “Captain America: The First Avenger,” Margaret “Peggy” Carter stole the heart of every moviegoer. Peggy Carter is one of the most important characters in the Marvel Cinematic Universe and it shows with her continued appearances both on television shows and movies. She fought for the Allies in World War II, moved to New York to work for the Strategic Scientific Reserve, and then helped bring S.H.I.E.L.D. into the world. She ultimately was granted her own television show appropriately titled “Agent Carter,” but ABC cut the show after only two seasons. So this one’s for you, Peggy. We miss you.

1. She defied all prejudices

Peggy Carter always faced ridicule for being a female in the field. She never backed down, though, and I think that's why so many people like her. She's relatable, and she fought against the patriarchy.

2. She helped others to do so too

Dr. Jason Wilkes was a scientist introduced in the second season of Peggy's show. He was continuously slandered for being a black scientist in the '50s, but Peggy once again didn't back down. She lifted him up in true social justice warrior style.

3. She was the basis for S.H.I.E.L.D.

The intelligence group that keeps the world safe? Yeah, she helped create that.

4. She was the one who Phil Coulson looked up to

Season three, episode 20 of "Agents of S.H.I.E.L.D." showed Coulson mourning after Peggy's death before he explained to Agent May that she was the one that inspired him to become an agent himself.

5. Her love for Steve Rogers

She never gave up on him, and if that's not relationship goals, I don't know what is.

6. How everyone knew about their unrequited love.

Okay, so this scene broke my heart in "Captain America: Civil War." Their love quite literally transcended time, but with great love comes great loss.

7. Her fashion sense

Need I say more? She's stunningly gorgeous.

8. ...and how she still kicks major butt

Gorgeous and fierce.

9. Her twisted sense of humor

I'm just saying that I wouldn't want to be on her hit list.

10. Her relationship with Jarvis

This dynamic duo leaves nothing to be desired. #FriendshipGoals

11. Her relationship with Howard Stark

Howard Stark often supplies the comedic relief in the show, but when push comes to shove, they can always rely on each other.

12. How much others respect her

Her boss (Chad Michael Murray) even believes she knows what she's doing. It's basically confirmed that she's the best agent.

13. Her sassiness

If glares could kill, Peggy would be on the FBI's most wanted list.

14. Her overall cuteness

Come on. Who doesn't think she's a cute warrior?

15. Fnally her independence

Peggy is one tough cookie and fiercely independent, but that doesn't mean she doesn't absolutely cherish the people in her life.
