Lucario can kill, and when he can't he has the power to combo the piss out of you till he can with his low knockback moves with little lag and awesome priority. And when he can kill you, the same thing applies except he kills you instead of comboing you as much...
@rayku- f-air > d-air works almost all the time and you know d-air is a very potent kill move. F-smash is also very unpunishable and kills.
I've said this a lot. When Lucario is at low percents, his high combo ability doesn't really serve very much because of the low reward. They do very little damage. 3% F-air's anyone?
At higher percents, his combos become tech chases once they get you to about 40% or higher. It's like fighting Falco in Melee. Really annoying, and (because I suck at Melee) impossible to tech at the right time
The only thing broken about Lucario, in my honest opinion, is his upthrow growth. That's where he gets his kills.
F-smash can be powershielded and punished by a lot of the cast. I guess that requires more accurate timing, but it's still very possible.
Yeah, F-air > D-air does work MOST of the time, but if you DI up on the F-air you get sent above him, where N-air is the only option. Even though that is a pretty good kill move at higher percents, too...
