With that in mind, one character who is smarter than Tony Stark is Samuel Sterns, AKA the Leader. A former janitor from Boise, Idaho, Sterns was infected by gamma radiation and consequently transformed into a highly intelligent creature known as the Leader.
Tony Stark
While Banner is an expert in biological sciences, Stark mastered mechanical and electrical engineering, and he is an expert in chemistry, computer science, and physics. While in a cave with little technology, he created the first Iron Man suit, proving Tony Stark was one of the smartest Marvel characters.
When it comes to the smartest Avenger, it has to be Iron-Man that is considered to be the most intelligent. While he and Bruce Banner are likely on a level when it comes to their scientific knowledge, the fact that he retains that when turning into Iron-Man just edges him above the big green guy.
According to the Scientist Supreme, Peter has an IQ of over 250.
Abilities. Super-Genius Intelligence: Tony is a phenomenal scientific genius and inventor with an IQ of 186.
Thanos' IQ is over 9000.
Super-Genius Intelligence: Van Damme held multiple doctoral level degrees and an IQ of 198. Doom was a child prodigy and scientific genius though unlike Richards he approached science as an art rather than as a system.
1. Rocket Raccoon. Rocket famously said that Tony Stark was only smart for Earth, and he's proven time and time again that he's the smartest character in the MCU. He can think his way out of almost every problem, create a gadget out of basically anything, and is now the official leader of the Guardians of the Galaxy.
I know this might sound crazy, but his IQ is most likely 160+.
The original question was: “Is Tony smarter than Bruce Banner?” Banner is the smarter “Smart Guy.” The writers/directors/producers answered this in Age of Ultron and Endgame.
Steve Rogers aka Captain America is the best example of someone who showed the bravery of a hero before they were a superhero.
Many things can be said about Amadeus Cho. He's the seventh-smartest person in the world, he's Korean-American, he's friends with the Hulk—and he even became the Hulk himself.
The world's smartest person with huge red dinosaur for an ally—life couldn't be better young Super Hero Lunella Lafayette, AKA Moon Girl. With her array of gadgets, her bizarre Inhuman ability, and her vast intelligence, Moon Girl has the brains to outsmart just about anyone.
As per the user, the director of Avengers confirmed that Thanos was most scared of Iron Man. “Not because of his strength, not because of his power, not because of his power, but because of his suit,” he added.
Pictured above, Terence Tao is said to have the highest IQ score in the world currently, with an impressive score of between 225-230. If the Chinese-American mathematician scored 230 he is definitely out in front. Effectively tying for the title, though, is Marilyn Vos Savant.
Marvel has seemingly confirmed that Doctor Doom is smarter than Iron Man. In Avengers: War Across Time #2, the team visits the Fantastic Four's headquarters in the Baxter Building, seeking a way to travel through time–and there they find Doctor Doom's infamous time platform.
Tony Stark is smarter than Peter.
Tony has proven himself to be one of the most intellectual people in the Marvel comics. He made his first iron man suit in a cave with few supplies. In the MCU, he doesn't get as many opportunities to show how smart he is.
1. Reed Richards. For many good reasons, many people claim that Reed Richards is the smartest superhero in comics. He's the leader of the Fantastic Four, an invaluable member of the Illuminati, and always called upon when “big picture” thinking is required.
A trivia published in BuzzFeed states, “Batman's stated IQ is an unbelievable 192, several notches above the famed theoretical physicist (Albert Einstein), who was estimated to have an IQ between 160 and 180.
Best known for developing the theory of relativity, he is amongst the top most geniuses the world has recognized. Einstein never took an IQ score test. However, based on his historical records, academics have estimated his score to be around 160.
IQ Level: 230
Moon girl is a self-proclaimed Smartest person in the Marvel Universe, and the same title was given to her by Amadeus Cho.
