NONE, Dunsparce looks better
It does in my opinion. You can't just have a pokemon look entirely different than what its type is. No, but everyone thinks a different way.
You either die a hero, or you live long enough to see yourself become a villain. -Harvey Dent
Look closely, because the closer you think you are, the easier it is to fool you. -Thaddeus Bradley
You can take away my toys, gadgets, and even my armor. But there is one thing you can't take away from me: Who I am. -Tony Stark
I may not remember who I am, but there is one thing I remember. I don't take orders. -Letty Ortiz
So, here's a list of Pokemon who learn Night Slash and are obviously Dark types.
There's more too, but I don't feel like listing them. I think I've made my point.
I hope Gamefreak reads this thread and makes Chespin Grass/Dragon or something ridiculous like that just to troll us.
