Unova is my favorite region, and Zoroark was my favorite Pokemon of all for a very long time, so long that I don't remember why. Maybe it was the colors, or its ability, or it was because, of the few issues I read, it was a primary character of the Black and White Pokemon manga, but whatever it was I've since forgotten. Being from Unova probably had something to do with it.
Flash forward a good amount of years, they reveal Hisuian Zorua, and I fall in love immediately. I pick up PLA just to catch one, and I find out it has an even cooler version of Zoroark that it evolves into. It felt like it was made just for me. A white-and-red color scheme that becomes white-and-purple (my two favorite colors) when it's shiny, a sick type combo, and a super cool signature move, it was perfect.
So yeah, Zoroark is my favorite Unova Pokemon.
