Favorite moves include Crunch, Dark Pulse, Night Slash and Sucker Punch.
Favorite Pokemon include Tyranitar, Greninja, Hydreigon, Krookodile, Bisharp, Umbreon, Scrafty... I could go on for a while.
I like this type so much that I broke my own personal trend of never doubling types on my main team (but technically one of them doesn't count. I'll explain why later). I've considered doing a mono-Dark team, and I'll probably get on that soon.
