Well I'm sorry, you're not iron man

I wouldn't say a fighter pilot has superpowers. The iron man suit has power not the user.

Iron Man is a better example of a superhero who created powers for himself, but he isn't one of the three most popular

His superpower is plot armour.

His superpower is being rich enough to be called eccentric instead of just crazy. You know, crazy, like the label used on all the villains he fights.

So, steroids?

due to being rich is able to get great equipment to use.

That's the power: gadgets. And also being a genius detective, but largely the gadgets.

The biological webbing coming from his wrists was stupid. If it was a spider mutation, he should have had spinnerettes growing from his rear end. The handmade web shooters were way more logical.

I am a lay person when it comes to comics, so feel free to tear me apart here. Could Bruce Banner potentially be all 3? His DNA was able to absorb the gamma radiation (born with it), he then had the radiation thrust upon him, and then he did whatever he did to make himself the smart hulk?

A bit of a reach, I know.

Wolverine was born with healing factor, trained in his fighting skills and then had his admantium skeleton thrust upon him

Naruto i guess? He's a child of a very powerful ninja(born), had a powerful creature sealed inside him at birth(thrust upon), and have to learn how to actually unlease and control that power(create).

Otherwise i can't seems to remember anyone that does have the 3.

he gained admantium skeleton, claws. but he had regeneration as a mutant so born with. also adamantium was poisoning him, so his regeneration was keeping it in check(weakening his regen abilities)

He has also trained himself to pretty much the peak of human limits, so there's that. Which is usually listed in other superheroes' lists of powers.

In different incarnations he's also heavily involved in the design of the various tech, it's more than just "being rich". That's really understating both characters.

But I would call super suits and super tech as "powers" in the way they're frequently talked about. Uber-genius intellects maybe.

Batman and Stark both have significant physics bending powers. It's more obvious with Stark, but both of them have made plenty of things that have bend the laws of physics pretty drastically.

The irony is Wayne had stupid amounts of money and chose to use personal violence to stop some of the criminals in Gotham rather than funding programs that would have lifted people out of poverty and prevented far more crime, or running for office himself and setting up oversight to stop corruption and programs to offer a hand up to people.

Also, Batman was born with his power. (His power is money).

I thought he had powers because he was born on Krypton under a red sun, and all Kryptonians gain superhuman powers when exposed to a yellow sun.

Seems a bit daft of the Kryptonian folk to stay there even if they didn't believe their planet was doomed.

"Move to another planet to be a nearly indestructible God who can fly and shoot lasers and stuff? No thank you. I just got my cabinets arranged how I like them and I am not going through that again."

I think it was from Kill Bill, but thrtrs a cool speech about how Superman has to put on the costume to become Clark Kent. While other hero's have to put on the costume to become the hero.

I get the inborn super-healing, and I get the addition of the adamantine (sp?) skeleton, but what powers did he create on his own?

Martial arts ability?

In the original story Batman has "bat senses" that allow him to hear the conversations of criminals, a bit like The Shadow. It used to be believed by some that bats could sense in the "ether", sn invisible river in which electromagnetic energy flowed, this was before echo location was proven.

And a psychopath with a fixation on criminal justice

the classic "ive only vaguely heard of batman" take
