Simple rules. Name a single superpower that you would like to have. You can say why you might like it if you want.
Rule 1 - It can only be one super power, it can't be a cluster of powers, like flight + lazers + super strength, you can only have one at a time
Rule 2 - No god power mode, kind of like rule one, you can only have the one power, and god mode would count to do anything you want.
Then, the next person to post has to write up why the above persons chosen superpower would suck, either a reason why or make up a scenario how it could go bad having that power.
Invisibility, being able to hide from sight and watch people without them knowing I'm there.
