I just like drawing certian Pokemon. My favorite is Articuno and Lugia, I also like Espeon and Umbreon. Some Pokemons designs are really pretty together, and make a great love story together tieing in with with game plots.
I never knew what shipping was until Bulbagarden. I liked drawing Pokemon together but never knew it was called that so I'm still not sure exactly what it means, besides writing stories and drawing Pokemon related characters together as a couple.
