For the purposes of plot I have access to a device that is capable of giving people comic-book style superpowers, its simple and painless to use, the catch is that its only able to give a specific superpower to a single person at any given time.
So if someone chooses super-strength for example then no-one else can have it at the same time, its first come, first served.
In addition the new abilities are impressive but not godlike, someone with super-strength can bench-press a truck at maximum effort but not anything more, someone with super-speed can break the sound barrier with a long enough run-up but not zip-around at close to light-speed…you get the idea, impressive but limited. And no abilities that are over-powered by definition, like ‘omnipotence’ etc
So what new superpower do you want, and what do you do with it?
Bonus points for a Straightdope superhero team name.
