That's biology, specifically osteology and neurology.@REL
Funny you mention canines since they can be trained to stand on two legs as part of trick. Lucario could have learned to try and balance himself on two feet on his own if it was the best way for him to fight.
In the absence of this, there are still his "fist-ppikes" he has that he could use to maybe backhand Yoshi in the head with after a lunge. Hell, that one on his chest could be dangerous if all of them are sharpened in some way. With a grinding stone of some type.
No Aura for Lucario, that I am in agreement with...or am I? World History really does come in handy when you have an interesting teacher.
He showed us something having to do with a person's spiritual aura (I did this on my brother and it actually worked! He is many times stronger than I am!).
What you do is have a person put their arms out as if standing like a cross. Then tell them to resist you as you try to push them down. They do so. Now take your hand cut them in half with it all the way down to the feet down the middle.
Tell your subject to put their arms out. Low and behold, they cannot resist you pushing your arms down.
So perhaps Lucario having the ability to disrupt an opponent's spiritual aura isn't as far-fetched as it sounds?
Both account for a great deal of the spiritual aura in the world.
Honestly, take every martial arts concept from ninja magic (any of the various types attributed to ninjas) to manipulating other people's chi and I can explain it in raw scientific terms.
Great ideas, and amazing that a lot of these things were so consistent, but their explanation was total BS.
