I think we'd have to go with Silver for our choice, but it's kinda close. Hugh was a really nice change of pace, where you get a rival who's both a friend, *and* a jerk, as opposed to blue and silver who are just jerks (though silver gets some really good character development and becomes less of a jerk, though he's loathe to admit it) and the rivals in all the other games who are friends
