I just tried him out. He's awesome!
His final smash is completely epic.
You made him teleport then teleport to the spot. Then he throws it down and when it collides with the ground the black rocks from Lucario's FS graphic is there which makes it look like an awesome collision. Then...it fading into a white screen like that is amazing.
His throws are especially great, as well. I like the UpThrow and down throw the most.
Also, nice secret taunt. (Aerial

)
I'd make a long discussion of each other move but these are the things I've come across that are different from the beta test version.
EDIT: Also, nice CPU AI!
One thing that makes him feel slow for me is either his running speed or his air mobility. But I can easily edit both of those in attributes. Again, great job.
