i wanna be able to communicate with animals!

Being invisible would be the first one. Then... fliyng and walking through walls. Communicating with animals would be just fantastic, but I suspect we don't really need any superpower to do it, just comprehension wish – maybe it was completely natural long ago, and now we're too egoistic to have that ability... :)

That would be to fly.

I´d love to flyyyyyyy so that I could be able travel all around the world ^_^ In addition, I´d love to have the power to return back in time....and to live again especial moments as well as to fix some others

I'd love to master the game of 'Go'. Superpowers are needed for that kind of insight.
