Default [Q] OK Google Now, What's Up?

OK Google Now, What's Up? "Hello Inigo Montoya, the time is 5:30pm. Not much going on right now".

I love that it does this, but I don't love that it uses that name. Where do I change this so it will call me whatever I want it to be? Do I have to change my whole Google+ account name to change this? Let me know if you know.
