Well, I'm going with Gible when I get one because of its speed and Rough Skin, although I'd suggest Salamence. It has better all-around stats and coverage, and Moxie and Intimidate sure are helpful. Garchomp is a fast dragon, Dragonite is a bulky dragon, and Salamence is in between.
As for the Demonata, it's a good book series. I know you've heard me mention Lord Loss before, but Bec is a girl in the series, and also the name of one of the books, and I'm going to name the Ralts (to be a Gallade) Slawter, the name of one of the books. My first three were a transformers trio. (Everyone knows Optimus. SoundWave is the satelite one in the movies, and Frenzy is the decepticon who transforms into a boombox/cell phone.
Believe it or not, all of my Pokemon are named like so for a reason.
