Yeah, it does.
He is nearly 100% ready for serious matches. He lacks only slipping animations, swimming animations, victory animations, taunts and 100% ledge stuff. There are some things that don't work well right now (he still can crawl, but doing so crashes the game because there are no animations), but should be easy to fix. Not sure if he has any problems with items outside of having Lucario's animations.
Speaking of leftovers from Lucario...

He can wall jump and wall cling. Ridley could do that as adolescent Ridley, so, might as well leave it. Wall clinging with him seems to be very hard to do for some reason (probably because he is too big or i can't do it properly). I did that by accident before taking screenshots.
