N is the coolest hippie ever. I donno, I just really liked him. xD;
He's one of the cooler looking characters, though I'm not allowed to point that out.
He's one of the few Pokemon characters that actually has a backstory, and I guess I just feel sorry for him, especially since I can imagine how Ghetsis treated him and all. He was also one of the most fun to fight in the Pokemon games, since his Pokemon switch every time, so you don't know what's coming.
Oh, and he has green hair. Screw the rules, he has freaking green hair.
