Tony

Best super power ever! Just ask Bruce Wayne.

Money that he mostly earned himself

But was heavily born into

I mean, he still has a big brain

Where’s his medal?

Genetic mutation of a human is still a human. Where as two non super powered humans might be born with slightly different levels of strength or reflex and potential, but the difference in a ability between a pro athlete who isn’t on drugs and a “normal” person not on drugs isn’t as huge as the difference in strength between a pro athlete and a superhuman.

So Tony Stark is smart. Smarter by far than most any human alive. We see through the iron man films as others struggle and fail to reproduce results similar to what he got in a cave with primitive tools and an untrained lab assistant but these others have massive budgets and access to the brightest minds on earth. As if endgame there is no evidence that anyone else save maybe the entire country of wakanda has created an arc generator without his help.

So his intelligence is superhuman in relative terms. He was able to figure out time travel, in a day or so- and is shown to be more intelligent than any human in recorded history by far. What’s more, many of our other hero’s who played pivotal roles but didn’t just happen to be in the right place at the right moment at the end also do not have super powers. The guardians of the galaxy for example each only have the abilities native to their respective races and while perhaps luckier or more skilled etc, aren’t indicated to be any more super than anyone else of their respective races. So if we are saying that anyone who when compared to an average human has abilities outside the norm or what is possible for any random person to achieve- Tony Stark fits that bill squarely.

I would be willing to bet money that not a single person reading this will invent a way to travel freely through time at will, and even building a true artificial intelligence is doubtful within the next decade even. So Tony Stark is super intelligent by human standards- and given how he’s stood against extra terrestrial threats and what we’ve seen of other worlds he’s, despite what Rocket said, intelligent by alien standards as well although more ignorant of certain principals that alien science is familiar with and earth isn’t.
