That picture looks amazing.
Anyways, please listen to all of what I have to say!
Firstly, this new pokemon could not be Lucario because of you look at Lucario's stat roosters, it has a total of 525, which it's evolution can have any higher. The max any non-legendary, non-psuedo-legendary, and Slaking pokemon has is a total of 555, and that's Arcanine. The pokemon trailing behind it have a total of 540.
See for yourself:http: //www.serebii.net/pokedex-dp/stat/all.shtml
Just see where Lucario is, and there is no room for Lucario's "potential" evolution in that chart. THEREFOR LUCARIO IS OUT OF THE PICTURE.
Secondly, earlier in this thread, I saw a link of a grocery bag of all the Pokemon that will be featured in the 13th movie. I was shocked to see a Mightyena. There is a small possibility that this pokemon could be mightyena's evolution though i cannot see how this pokemon's evolution will take over such an incredible role and possess supernatural powers, afterall, this is just a dark pokemon.
its ubsurd: like saying meowth, a normal pokemon, will evolve into a jirachi, which is a psychic and has a psychic ability (bringing wishes). put some logic and sense into this.
thirdly, this pokemon has more non-ghost features, it appears as if it were a fox, a canine, or feline, maybe a rodent, and as u can tell it has hair/fur. this pokemon could be somehow related to the 3 cats, but im just sayin that LOL. uhhhh and the only types this pokemon would most likely be is (from greatest chance to least) dark, normal, psychic, fighting.
