10 Smartest Marvel Characters

10. Ironheart (Riri Williams)

With Endgame on the horizon, it genuinely looks as though Tony Stark will be leaving the MCU for good. If this does happen, there are actually several individuals that could take his place from the comics, but only one matches his intellect and is arguably much smarter than Marvel’s most narcissistic genius.

Riri Williams impressively attended the prestigious school known as M.I.T. at the very young age of 11, showcasing her next-level intellect. Four years later, this whiz-kid would construct her own Iron Man suit, accomplishing this amazing feat at a much younger age than Stark initially did (although he did make his in a cave with a box of scraps).

This master engineer, who was mentored by both the real and artificial intelligence versions of Tony, goes by the name of Ironheart when she is suited up and ready to take on the forces of evil. She is not only a natural born powerhouse of intelligence but she was schooled by the likes of the original Iron Man, who - to say the least - knows a thing or two about science.

Her advanced intellect for her age, her ingenuity with engineering - as well as her being the prodigy of the infamous Tony Stark - more than sets her apart when comparing all the different IQs of Marvel's finest.
