If I lived in the hypothetical Pokemon universe and had to just have one Pokemon, it'd have to be Lapras. It's a bad-ass Loch Ness monster/dinosaur cross that shoots ice out of its mouth and gives you free jet-ski rides! That in and of itself would be enough for me, but it's also great in battle - a tank, almost! - has a great voice and can help me whenever I get a bout of insomnia.
