IRON MAN / TONY STARK - portrayed as a billionaire businessman who operates as a superhero using powered armor. He is also one of the founding members of the Avengers and the CEO of Stark Industries. Tony Stark, the man behind Iron Man, is known for his genius, billionaire status, and former playboy lifestyle, all while being a philanthropist.

HULK / BRUCE BANNER - Bruce is a genius as an expert in gamma radiation. He is overly sarcastic by guessing Hawkeye's joke. After having exposed to the gamma bomb he gained another personality that is monstrous, called the Hulk, that he can change into after his heart rate goes at a certain point by getting too stressed. He tries to maintain his heart rate by calming himself down, but it seems that he's able to bring out Hulk by will alone (it could be theorized that Bruce's heart rate is something he cannot always control, thus he can sometimes bring out the Hulk not by his will). Bruce cares for people especially ones that have been radiated with gamma rays, even trying to help Absorbing Man. Bruce distrusts S.H.I.E.L.D., as he thinks that they will use the gamma radiated mutants as weapons of mass destruction for themselves.

As the Hulk, he is very brutish especially when he transformed the first times, causing the destruction of his surroundings and beating anything in his path. After some time, Hulk started respecting people and had the thought of helping them instead of hurting them, such as when the Hulk rescued Hawkeye's men from a helicopter crash. Hulk can talk with Bruce as his dormant persona and decided to join the Avengers to help innocent people and show them that he can be good in exchange for staying as the Hulk.

Hulk is very egotistical when it comes to his fighting prowess, regularly calling himself the strongest there is and laughing at Hawkeye when he said he could take him down. He is also very gruff, and sometimes grumpy, and very rarely shows any emotion other than anger, though he does have a soft side. He can get along with people very well, but can be easily irritated by others if they think that Hulk is only a monster. Hulk has a trait to call people by nicknames that he comes up with, like calling Thor "Goldilocks" and Hawkeye "Cupid".

THOR ODINSON - Thor is portrayed as a powerful and honorable Asgardian god, initially arrogant and prideful due to his immense power and status as a god. He is brave, courageous, and willing to defend Asgard and the nine realms. The series also explores Thor's growth and development, showing him learning humility and understanding the value of teamwork with the other Avengers.

WASP / JANET VAN DYME - Wasp is enthusiastic about being an Avenger, and crime fighting in general. She appears shallow and self-absorbed at times, but beneath it all she is a compassionate person who is willing to reach out to others in need, and genuinely cares about others. An opinionated individual, Wasp is not afraid to share what is on her mind and firmly stands up for what she believes.

She likes to have fun and hates being bored. She is laid back and light hearted, and finds seriousness stifling. She is also likes to talk smack to her enemies. Despite being an adult, she has shown some very childish behavior, such as when she mimicked Hulk's angry face and stuck her tongue out then turned away.

CAPTAIN AMERICA / STEVE ROGERS - democracy. He fought HYDRA and the Red Skull very bravely in WWII until he fell on ice and frozen for decades. As he woke up, he mistook the Avengers as HYDRA agents until the truth was revealed to him by Wasp. After realizing the truth, he went into stupor and put down his shield. He finally went back to battle as he fought Zemo, former leader of HYDRA. He now fights beside the Avengers to make a better world.

Captain America has the ability to talk to anyone in a calm matter, hero or villain. His speeches are known to inspire others and often turn the tide of a battle. With Hulk once, he surprised Hulk with his word (hero) he used to describe him and drove him to fight harder by inspiring him to smash more HYDRA goons, much to Hulk's delight. It is possible that this trait made Tony Stark believe that he would be a better suited leader than himself.

He seems to have very strong political views, possibly due to his original birth year taking place during World War II. Steve's sense of justice made him a more difficult opponent to defeat while fighting villains, mainly because, he knew if he failed, the Earth's people and fate would be doomed. One of his most defining moments was when he fought against the Skrull impostor of him during the Skrull invasion, taking place shortly after his escape from his Skrull captors. He could have given up, due to the many hits he sustained. But instead, he continued to fight and even gave another speech about human's and their overall selves, possibly to encourage himself.

BLACK PANTHER / T’CHALLA - T'Challa is a man of responsibilities. He felt guilty for not saving his father, T'Chaka, from Man-Ape's wrath in the challenge of the throne of Wakanda. He dons his new Black Panther suit to go to the outside world for help. He also seems to have a less traditional and more liberal view than his tribe, as he did not listen to the tribe's customs to follow Man ape after he defeated his father since tradition says they need to follow the leader no matter who they are. In addition, he does not believe in cutting off contact with the outside world but instead need to open themselves up or else make themselves vulnerable. He believes in maintaining a close eye on his comrades, which to some may imply that he doesn't trust them as much as he should.

CAPTAIN MARVEL / MS. MARVEL / CAROL DANVERS - Before becoming a superhero, Carol was dedicated in her work and achievements, never allowing the antics of others like Wasp to distract her or others from their more important and urgent matters. She believed in keeping a professional level in dealing with other coworkers. Even without powers, she was shown to be brave and bold, even questioning to bring in any of the other Avengers outside of Wasp and Ant-Man. Only when a situation seemed disastrous did she even consider changing her mind. She protected and helped others. She was shown to have a dry wit and that she has a short temper. She also seems to be quick to judge others. In that she is not unlike Janet Van Dyne. Her personality is practically the same as her comic book incarnation's own.
