Real life...
You have been taken away, experimented on and dumbed back into your apartment/home. You have an envelope right beside you with your name on it. You open it up and discover that you were given new powers and abilities and it gives you a brief description of what you can do. Which power would you choose? You have not received a lot on how to use your new abilities. This is something that has been thrown on you. You also have to remember the other consequences that comes along with living in today's time with these type of abilities. Your powers are active as soon as your done reading the envelope.
Your choices are...
Colossus
Nightcrawler
Wolverine
Beast Boy
Mystique
Gambit
Kitty Pride
Cyclops (you receive a pair of visors)
