Avengers: Endgame had some pretty iconic scenes, but amongst Thor's hammer, and Thor gaining a lot of weight, we saw all of the female heroes come together in one epic shot towards the end of the film.
The scene has been coined as being the new "MCU, so it would make sense if this is what the Russo's were hinting at when they included this scene.
Here is every member of A-Force and which Hogwarts House they are sorted into:
Captain Marvel - Gryffindor
Spider-Man carry the infinity gauntlet in the film's final battle.
The Wasp - Gryffindor
The Wasp spent a whole 5 years being "dusted" after the events of Avengers: Infinity War, yet when she gets brought back, she slots straight back into battle without hesitation. Her knowledge of the quantum realm is what helped the heroes return the stones and bring everything back to normal, and the fact that her dad is the original founder of Pym particles mirrors that of a typical Gryffindor who has parents that are just like them.
Okoye - Gryffindor
Okoye is one of the only survivors of the snap from Wakanda at the end of Avengers: Infinity War.
Okoye loses basically everyone she is close to, but shows great nerve in the way she carries on rebuilding Wakanda in the 5 years that the heroes try to move on. Okoye is also an incredibly skilled fighter and hopefully will return in the next phase of the MCU.
Pepper (Rescue) - Hufflepuff
Pepper Potts shows great loyalty towards Pepper still showed loyalty to Tony in ing him when he figured out time travel.
Wanda Maximoff - Hufflepuff
Wanda devotes her life to Vision, the part human/robot/infinity stone/AI creation that is created in Avengers: Age of Ultron. She is kind to Vision and makes him feel human, and isn't shown in the way you'd expect her to, when her comic book equivalent Scarlett Witch is a lot more villainous (not yet anyway). Wanda loses Vision to the wrath of Thanos, and despite years of being out of the field, still returns at the end of Endgame to show Thanos she has not forgotten what he has done.
Shuri - Ravenclaw
Shuri has been spoken about by various MCU directors and cast as being the most intelligent character in the whole MCU, and they aren't wrong. Her Black Panther using the Vibranium found in Wakanda.
Mantis - Ravenclaw
Mantis doesn't appear as much as the other of A-Force in the MCU, but she definitely plays her part in the battle to defeat Thanos. Her powers mean she is feel and alter people's emotions. She can also put people into a deep sleep and is able to do this to Thanos in Infinity War. Mantis' wisdom in Guardians 2 also helps them overcome the Celestial, Ego.
Valkyrie - Slytherin
Valkyrie came into the MCU first in Slytherin.
Valkyrie also appears Endgame frequently and is not the friendliest of all the A-Force heroes when Hulk and Rocket turn up to New Asgard in the hope of recruiting Thor back to the team.
Nebula - Slytherin
Nebula is a typical Slytherin, it's not quite clear if she is even a hero, however she definitely sides with the A-Force in Avengers: Endgame. Nebula is Thanos' adopted daughter and worked with him for many years scheming across the galaxy. The Nebula from the past ends up being killed in Endgame, while the Nebula from the present survives, so technically she is on the right side…but her morals are definitely questionable.
Gamora - Slytherin
Gamora is another adopted daughter of Thanos and the good version doesn't actually feature as a member of the A Force because Thanos killed her whilst he was acquiring the soul stone on Vormir. The pre-Guardians version of Gamora is the one we see in Endgame, and although she comes to her senses in the end, quite like her sister she is still an intergalactic criminal.
