Superstrength and stamina. You'd be a beast in any physical activity.
Mind control, duh. How cool would that be?
The ability to see the future. Will we live on another planet? Will there be unicorns? Who knows? You do.
The ability to create peace. You're so tired of petty drama and pointless arguments.
Time-travel. Very Doctor Who.
Making mistakes. Knocking things over. Just being clumsy and unlucky in general.
Anything that requires physical exertion.
Giving advice to anyone that asks. Sometimes you don't even know why they ask you these things.
Stalking, lurking, research... whatever floats your boat.
Being the class clown.
Being buff. Nuff said.
Always being the reliable friend.
