Before the events of Infinity War and Endgame, the answer to this question was clear. Due to his status as a synthezoid, Vision doesn't need years to lend some serious wisdom to the team. At the time of his death in Infinity War, Vision was only four years old, which makes him the youngest Avenger by a long shot.
Last but not least, Vision becomes the youngest character in the MCU among other characters. He appears in Avengers: Age of Ultron for the first time because of the power of one of the Infinity Stones which is Mind Stone.
In the Marvel Cinematic Universe's third phase, Spider-Man made his dramatic debut as the youngest and funniest Avenger yet. Peter Parker went from being a kid in Queens to a great costumed hero.
Thor. While Steve Rogers gets the title of the oldest human avenger, Thor Odinson, as the mighty Asgardian God of Thunder, has a much longer life span than any of his Earth-born friends.
While giving Star-Lord, Gamora, and Drax a tour of his planet, he told them he was millions of years old. He can only be truly killed if his true form, his brain, is destroyed. Nigh-Omnipotence: Ego's Celestial genes allowed him to do nearly anything.
Tony Stark and Pepper Potts' daughter, Morgan Stark, was introduced during Avengers: Endgame.
Shuri. Shuri is 3 years older than Peter, having been born in 1998. However, that didn't stop many fans of the MCU from shipping the two characters together. It's easy to see why - they're both extremely intelligent, not always so good in social situations, and focused on helping their families.
Technically, both biologically and by the number of celebrated birthdays, Peter Parker is still 16 in October 2023, when 'Avengers: Endgame' takes place. However, his body would turn 17 on December 27, whereas he wouldn't 'count' his 17th birthday until August 10, 2024.
In the animated series “Marvel's Moon Girl and Devil Dinosaur,” the superhero exploits are based in relatable teenage emotions and concerns. “One girl can make a difference.” That's the mantra of Lunella Lafayette, a precocious, Afro puff-sporting, 13-year-old New Yorker whose alter ego is the crime-fighting Moon Girl.
Gorr's Daughter Love is Chris Hemsworth's Real-Life Daughter
Jane Foster promises Gorr with her own dying breath that Thor will take care of the child, and Thor, now heartbroken and alone, chooses to adopt the child. But in real life, the actor that plays Love is actually Chris Hemsworth's real daughter.
Captain Marvel is long-lived, but she is not immortal
She is simply extremely long-lived. Her alien physiology slows down the decay of her cells and prevents her from aging in a manner similar to a full-blooded human being.
Hulk (Bruce Banner) is the third oldest founding member of the Avengers, behind Thor and Captain America. Having survived the Thanos snap, Banner is about 54 years old during Avengers: Endgame.
As Bruce Banner, the character is about 5 ft 9 in (1.75 m) tall and weighs 128 lbs (58.05 kg), but when transformed into the Hulk, the character stands between 7 and 8 ft (2.13 - 2.43 m) tall and weighs between 1,040 and 1,400 lbs (471.73 - 635.02 kg).
I'd say around 220. (Spoilers ahead.) If we look at just the MCU version, Shuri is not only a tech genius, but she understands enough about the nature of vibranium to build a suit that can store and release kinetic energy at will.
Shawver has revealed that a romantic connection between the new Black Panther Shuri (Letitia Wright) and Talokan's ruler Namor (Tenoch Huerta Mejía) was explored in some takes. Before their epic showdown towards the end of the film, Shuri and Namor had been quite cordial with each other.
There were many rumors, hopes, and insinuations made by fans about her potential relationships, but the truth is, nothing ever happened, really. Just like in the comics, Shuri didn't have any significant romantic relationship or encounter so far in the MCU.
Iron Man
Superhero Tony Stark is adopted. Many kids love to dress up as the iconic Marvel superhero, but may not know about his complex family history. Tony's brother, Arno, is the biological son of Howard and Maria Stark.
Fictional character biography. Skaar is the son of the Hulk/Bruce Banner and Caiera the Oldstrong, an extraterrestrial native of the planet Sakaar. He was conceived during the Hulk's time on Caiera's home planet of Sakaar.

1 Reed Richards
Throughout the character's history, he has been consistently cited as the most intelligent being in the Marvel Universe, justifying this affirmation time and again with his discoveries and innovations.
Abilities. Super-Genius Intelligence: Tony is a phenomenal scientific genius and inventor with an IQ of 186.
I know this might sound crazy, but his IQ is most likely 160+.
