Who would you pick and what would you want to do?
Okay, it's not the best question, but it's pretty late at night, and I can't think all that clearly, so I just came up with something fairly random. At any rate, my answer would be:
Cyrus. He's my favorite member of Team Galactic (heck, he's my favorite character in Pokemon, period). Even though hanging out with him is probably like hanging out with a rock, the only difference being that a rock doesn't take out its laptop and start working when you're trying to hang out with it, I still think that we, or rather I, would have fun. At first, he would most likely ignore me completely what with being dragged on an outing by some random person. After hearing me saying that I totally get where he's coming from, however, he might actually show some genuine interest, if only because he would have nothing else to do. So I guess we could spend the time talking, as I doubt he'd be up for anything else.
I would hang out with Commander Mars, personnally. :)
