I've thought of a really fun one:
Super gymnastic skills!
Like the ability to jump 10km in the air, do heaps of flips and stuff, travel faster than aeroplanes, do awesome parkour skills, land safely from any jump or fall etc.
But it really depends if I'm the only one with superpowers or if everyone in the whole world gets a superpower...
Why would you want to be able to teleport? Apparating would be heaps cooler and Wilky Twicross could teach you.
Yeah that would be so cool dressing in ghost clothing and scaring people!
There's the ink series where the dude writes stuff and it comes to life. I think that was idea of the book. I haven't read it but I heard about it.
I think I remember something like this on The Twilight Zone.
