Eh. We haven't really talked much about Lucario vs Ness. In my opinion I'd like to think that it's 60:40 if not 55:45 in Lucario's favor. Here's from my experience.
- Aura Sphere can be absorbed or reflected.
- Both can gimp each other fairly well. Like Lucario being able to fly onto the stage instead of just the edge, Ness can also do the same..
- Lucario's Double Team or whatever it is can kill but can also be dodged if you're quick enough.
- A lot of Lucario's attacks seem disjointed in a way. His dair is probably tougher to get by than Peach's dair and so you don't want to spot dodge that though it may very well happen.
- Lucario's Force Palm can be absorbed if at a close distance, but not to the point you'll get grabbed by it.
- Basically his aura has a big hitbox, so it's hard to get through.
For Ness, I know how fair can cut through a lot of Lucario's attacks, but I think Lucario's attacks might come out a bit quicker than his. Anyway, like I said, I don't have much experience against this character. I don't really come across that many Lucario's and when I do, they just spam Aura Sphere.
I mean it's not a problem for me since they just give me free health, but I know there are better ones out there.
