Five Seconds of Power

You are participating in a new study by L&G Inc. Though the compensation isn't very good, they could be the key to your dream of having superpowers. After weeks of pokes and prods, and far more mental and physical tests than should be legal, you are one of the few whose power awakens! The catch?

You're stuck in this facility with a few powered individuals until you learn how to work together as a team of superheroes. Oh yeah, and everyone's power—including yours—is limited by 5 seconds in some way.

So why go through all this?

Because someone mentioned there would be a portal at the end of this training that could take your group anywhere, anytime. And did you catch the part about being a superhero?
