I finally realized what struck me as strange about the new Lucario sprite.
===>
They either screwed up the legs, or Lucario is double-jointed at the ankles. He shouldn't physically be able to kneel that way. As you can see in the images on the right, Lucario has hind legs like a dog's. He actually stands on his toes, his heels are higher up (the bent part below the blue part of his legs), and the knee is in the thicker blue part. In the kneeling image, the knee is below the blue part.
Either that, or Lucario has his "pants" rolled up higher :/
