I thought Delphox was a perfect evolution. They tried to bring a medieval trio to the starter evolutions and they did. Greninja being a ninja, Chesnaught being a knight, and Delphox being a wizard. Personally though I think they could have made Delphox a little less op. Mine is currently my strongest level pokemon when I barely use it. I just put my Delphox in my Battle Box along with my Mewtwo, Goodra, Gengar, Talonflame, and Dragalge.
It's not necessarily that I don't like it, more that I am disappointed. It is my own fault though, cause I was imagining something Ookami or Kyuubi like but bipedal, maybe something like Lucario. It doesn't look bad, just not what I was expecting. Although my friend showed me someone's drawing of it that made it look totally amazing.
And on that note this is a cool drawing too, I like the face and the flames/smoke
