Avengers
I will name off some characters without their own movies and some facts about them
(:
Baby Groot
A cuter version of Groot.
The Winter Soldier
Also known as Bucky Barnes, he and Steve Rodgers create the best bromance in history. Though he is sometimes a villain to the Avengers, he is a good guy. He once took over Captain America's job, along with Sam Wilson. I don't know for sure if I should call Captain America: The Winter Soldier his own movie, considering it is a Captain America movie, but I worked too hard on this to delete it.
Ronan
Also known as Ronan the Accuser, he is a son of Thanos. He is responsible for the murder of Drax's wife and daughter. At first "The Supreme Intelligence" called him "Supreme Accuser of the Kree Empire" until he changed it to Ronan the Accuser. His powers are; super strength, endurance, reflexes, and speed. His main weapon is the "Universal Weapon," which is a war hammer made by the Kree, often used by Public Accusers. Another character known to wield a Universal Weapon is Hala the Accuser, who is a Kree native, and is named after her home planet, Hala.
Drax
Although he calls himself Drax the Destroyer, he is soft. But he always seeks revenge on Ronan, a son of Thanos, for murdering his wife and daughter. He is a really loveable character and is very funny. At one point he is having a conversation with Mantis, and he said that she was hideous. Pay attention to him.
Gamora
Gamora is her only name, and she is Peter Quill's significant other. Her sister is Nebula, and her dad is Thanos. Her and Nebula have a complicated relationship, but they have sister love to get them through. Even though we can clearly see she hates him, she has a soft spot for Thanos. According Peter Quill, she is better with swords than guns, but she has a talent for fighting in general. She is a really important character, so yee.
Captain America: The Winter Soldier
Get to see the best bromance, Bucky and Steve
Groot
Groot is made of wood, but he is one tough cookie. His only words are "I am Groot," but we don't talk about the other line. Groot is a very good fighter, and he is important to the story Marvel is telling.
Black Panther
He isn't in any other movies except for one, which we will talk about later. (NOT HIS REAL OUTFIT)
Hawkeye
His real name is Clint Barton. He is great with a bow and he carries a quiver filled with "trick arrows." Hawkeye most of the time in Infinity War sits around and does nothing.
Spider-Man: Homecoming
Introducing the most adorable teenager on the planet :)
Tony Stark/Iron Man
Is rich
Iron Man 2
It is better and more important than either of the other Iron Mans
Quicksilver
Pietro Maximoff is a crossover from the X-men to the avengers. He first appears in Captain America: The Winter Soldier. He and Wanda (Scarlet Witch,) are fraternal twins.
Guardians of the Galaxy Vol. 2
Quill has Daddy issues (OPTIONAL)
Falcon
Sam Wilson, as said in the last term, also took the job of Captain America. We don't know too much about this character considering he is a new addition, but he has a cool suit.
Scarlet Witch
Scarlet Witch's real name is Wanda Maximoff, and she has super awesome powers, and she is one of the only people who can destroy the Mind Stone, which is one of the Infinity Stones. But the reason she doesn't is because it is the only way her love can survive.
Doctor Strange
So that you know who he is in future movies
Guardians of the Galaxy
So that you know who they are and their backstories (Quill has Mommy issues)
Rocket Raccoon
But you can just call him Rocket. His best friend is Groot, guns, other weapons, and prosthetic body parts. He is the reason Thor has two eyes! You can see his love for weapons and body parts when you first see him. He always denies that he is a raccoon, but lets Thor call him "Sweet Rabbit." He is in general just a loveable character. He is important in all of the movies that he's in.
Infinity Stones
Contain huge amounts of power and energy and can only be wielded by someone very powerful.
Corvus Glaive
Corvus Glaive is a member of the Black Order, an evil group lead by Thanos. He has powers such as; Super strength, senses, endurance, weapon that comes to his hand when called, immortality, and speed.
Loki
Loki, the God of Mischief, is Thor's adopted brother. He has immense power, which are; shape-shifting, super strength, manipulation, speed, longevity, durability, flight, energy blasts, inter-dimensional teleportation, telepathy, illusion casting, astral projection, deceit, and adorableness! Okay the last one isn't actually there but let's just put charming. (: Sometimes he is evil, but a lot of times he is really nice and him and Thor have a complicated relationship, but they are like Gamora and Nebula, they have sibling love.
Mantis
Mantis can read and control minds. A lot of times she gives away a lot of secrets about the other characters, such a Quill's interest in Gamora. She worked for Quill's dad and is introduced in Guardians of the Galaxy Vol. 2. She can also see into the future but doesn't use that to her full advantage. (No image)
Black Widow
Natasha Romanoff is her real name. Surprisingly, she doesn't have any superpowers, just pure talent in the martial arts. She also has some awesome weapons, such as; custom stun batons & "Widow's Bite" bracelets capable of stunning enemies with electrical discharges. She and Bruce Banner love each other.
Nebula
Nebula is another child of Thanos, and she is therefore Gamora's and Ronan's sister. Thanos would have Nebula and Gamora fight, and everytime one of them would lose, he would replace a part of them with robotic parts. Obviously, she lost a lot, and is made up of mostly robotic parts.
Peter Quill
Star-Lord kind of has his own movie, but it is shared with many other characters, so I am going to also list other characters like this. That is his real name, but he calls himself Star-Lord. His mom is human, but his dad is alien. His group called "The Guardians of the Galaxy" are made up of; Gamora, his love interest, Rocket Raccoon, his friend, Groot, his other friend, Drax, one who comes in a little bit later, Baby Groot, and Mantis, also his friend. Also, this dude is a turd bucket.
Thanos
Thanos is just a big butt. His only goal in life is to erase half of all life and make world peace. And he calls this mercy. He is the father figure for Gamora, and he is randomly turning different colors, because when he is first introduced he is purple, then he is blue, and now he is pink, sooo yeah. Evilness.
Avengers: Infinity War
Thanos is trying to destroy half of all life, and it is up to the Avengers and some new recruits to stop him. Also Thanos is Gamora's daddy (:
Nick Fury
That is his real name, but he likes to be called Fury. He started the Avengers. He is really important in a lot of movies, such as Captain Marvel, the soon to come Spider-Man: Far From Home, a lot of the Captain Americas, and most of the Avengers movies.

Valkyrie
Valkyrie was a group of women sworn to protect Asgard, but when Hela, the Goddess of Death's, power grew beyond Odin's, and she killed all of the Valkyrie but one, whose name is Brunnhilde, but she calls herself Valkyrie. She has durability, super strength, longevity, and speed. Longevity meaning a long life. She is an important character and may get her own movie eventually.
Vision
Vision doesn't have a real name, and he was made from Jarvis, whom you will see in Avengers: Age of Ultron. He is Wanda's love. He holds the Mind Stone in his head, which is keeping him alive. He is a very important character, so pay attention to him. Also, he is pretty much AI.
Avengers: Age of Ultron
When Tony Stark and Bruce Banner try to jump-start a dormant peacekeeping program called Ultron, things go horribly wrong and it's up to Earth's mightiest heroes to stop the villainous Ultron from enacting his terrible plans. 2015 (I totally wrote all of this)
