Honestly, based genie. Instead of fucking you over by twisting your wish into something negative, he fucks you over by spending time on small details. At least the latter will likely result in something you actually want, whereas the former will probably suck.
The original terms of the wish requested the ability to fly, not just wings. These are part and parcel to being able to fly with wings. Ergo, only one wish.
The genie grants your wish. You inflate via your own flatus. When you land, you have to release a fart big enough to buoyantly lift an entire human body.
I'm sure you mean grown up DBZ Goku, but I would 100% take a flying nimbus and putter around the skies on my little cloud buddy. Just remember to pack a parachute!
To steal an idea I had on something similar once, perhaps on an entirely different site, there's also where the wings come from in the first place, literally and figuratively.
The equivalent structure to a bird's wing in humans is the arm and hand. Does this new wing take the place of the forelimb as it does in birds or does the wisher necessarily become a six-limbed creature?
Except after the second question it makes generic assumptions and responds immediately from data it's hallucinated rather than backed up with facts, despite telling it to do so or having had explicitly shared with it the full context beforehand.
