If I have one it could be a superpower to generate another super power,infinite, all possible superpowers out there. Having that would be amazing and I will generate the ability to teleport anywhere I can think of(fan of tourist spots in the world).
Second would be the super power to generate infinite money but only limited to the blue bill(1k) of course hihi then save it as your source of funds for the rest of your lives.
The third one I will generate will be the superpower to prolong our lifespan but only limited to my family.
Last one would be the superpower to predict the future. If I have this one then I can prepare for the worst ahead of time.
Nothing else...I know that generating those various superpowers have consequences later on so lets limit to that only and will not go further more.
