[Hulk] What are Bruce Banners most impressive feats done without the Hulk?
gpt
Well, he's a super genius. He regularly invents things that are inconceivable to regular scientists. In the comics he invented the Gamma bomb that turned him into the Hulk. (It wasn't nuclear, but with the same initial destructive capacity and zero fallout) In fact, the only reason he had the accident was because an enemy spy working in the lab didn't halt the countdown. He was considered dangerous enough to assassinate. On top of that he built a bunker to contain the Hulk (back when he transformed every night) and device to transform himself into the Hulk. (It worked the other way for a while as well, but the Hulk built up a tolerance.)

That's just his first fifty issues or so. Since then he's gone full Super Genius; He stands up to the Son of the Hulk with a personal shield that feeds on Jr's powers. (He can also use it to augment his strength quite a bit) and he carries a personal teleportation device. And of course he does the whole hacker routine every now and then. 

Oh, and basically any anti-Hulk tech that's every actually worked, Banner helped with.
