You find out you have the power to turn invisible for 24 hours. Not in a row. You can turn it on and off, but you have 24 hours worth of invisilibity power. However, in order to activate your power, you have to eat a live spider first, and this explains why you never knew you had this power. Would you activate your invisiblity power, and if so, how many spiders do you think you'd eat in the course of a year?
You find out you have the power to teleport. Any distance. Each trip is a single usage, and once you activate your powers, you get 20 uses. The only way to activate your power is by having a threesome. Sex with two other people simutaneously. Things to consider are the monogamy of the relationship you're in now, if you're single is it hard enough to get one person to eff you, let alone 2, and the difficulty in setting up a threesome. Considering your own love life and the way it stands, how many teleportation trips you'd make in one year?
You find out you have the ability to heal people completely. Any disease, any wound, any affliction. In order to get 20 charges/uses, you have to activate your power. To activate your power involves taking one life. It has to be mammal. It can be a person/animal that's dying or elderly. You simply utter the words 'die' and that life is extinguished the next day, so you don't have to personally kill it. Each time a life is removed as such, you get 20 charges, to heal fully 20 people/animals. How many times a year do you think you'd use this power?
You find out that you have the power of super strength and toughness. You can lift 100x what you can lift now, and are 100x more impervious to damage than you are now. But, like the other powers, there's an activation cost. You must smoke enough meth to get wasted. After the effects wear off, you'll have super strength and toughness for exactly 1 week. How many times a year do you think you'd do meth?
You find out you have the power to stop time for 5 minutes at a time. Like the other powers, there's an activation cost. In order to stop time, you must consume 5,000 calories that day (up to that point). The calories don't get burned off from using the power, they just behave like normal calories, so probably turned into fat. How many times a year do you think you'd stop time?
