It's been over a week since we started talking about Jr, so let me summarize what the consensus is:
- The match-up is 60-40 for Lucario.
- Jr relies a lot on getting in and racking up damage that way. He has some decent strings and most of his moves come out reliably quickly. He's a heavyweight, and his clown-car defense allows him to absorb more punishment than other characters in his general weight area. Most of his kill moves come out quickly...
- ... but they have a ton of downtime, so if he misses, he can get punished with nearly anything, including forward smash. His projectiles are all widely telegraphed and are asking to be Double Teamed. Specifically because of his weight and gimmick defense, he's really easy to combo at lower percentages, and once Lucario's Aura is high enough, his spacing is too good for Jr to break through, including Force Palm, which isn't stopped by Mecha Koopas. While Jrs attacks come out quickly, they don't link together very well.
- Lucario beats him at lower percents by having a stronger combo game and he wins at higher percents by being too good at spacing.
The next match up to discuss, and probably one that a few more people have experience with, is
Falcon is an awkward match up to really describe. He's tied for 13th heaviest in the game and he's a fastfaller, so he's going to be hard to kill no matter what. He's absolutely a rushdown character and Lucario generally has troubles with characters that can outpace him - we lose at the early game because we can't space him, and, assuming both characters are at 100, a missed Force Palm or a hasty forward smash could get us killed out of a dthrow. This is one MU we can't afford to get too aggressive in, while Falcon lives and thrives on aggression.
Falcon has one of the best dash grabs in the game, if not
the best, and he will often search for it. I've found some decent success against him by predicting the dash grab (which isn't hard) and beating it with standing grab. I think our grab range might beat his, but because he slides so far on a whiffed dash grab, he can afford to go for them more often than we can.
I don't know the frame data on his jab, but it can't be more than three, and that makes him difficult to approach from... anywhere, really. If you try to dash grab, he can just Gentleman you away. From the air will get you uaired. You can try approaching from beneath him if you catch him on a platform, but with quick, powerful moves like nair and bair, he has no problem getting down, so you better know what you're getting into by challenging that. And speaking of bair, be very careful if you're recovering and he's near the ledge: a trump to bair is bad news, but also, his utilt can spike now and the hitbox reaches beneath the ledge slightly, so be ready to curve your ExtremeSpeed if you gotta.
All this said, let's talk about how Lucario can win:
If your fingers are fast enough, Lucario has an easy time comboing Falcon at almost any percent (outside of kill percent). Because of his weight and fall speed, uthrow will mix and match with any short hop aerial or utilt. Falcon's dair isn't very good for getting him down, so if you can get him above you (without a platform) then he's relatively easy to harass. Aside from his jab, he also lacks a good "get off me" grounded attack like our utilt, so if you're not directly in front of him, his best options are to try and turn-around grab or to just run away and reset.
Falcon has no projectile, so once our Aura gets high enough, we can push him away with a Force Palm and then the
threat of a follow-up Aura Sphere. He's difficult to keep out, though: if you miss or you're shielded from a few strides away, he has the running speed to get back into us before we can follow up with anything. He also has a very linear recovery, which is easy to punish with dairs or dropzone Aura Spheres.
He can kill quite early if you let him: his smash attacks can kill starting around 110, 120-ish. His Knee will kill about the same time. Raptor Boost will kill slightly later, I think? Landing them is pretty tricky for Falcon because if we're in kill percentage and he flubs, a grab and a few aerials will even the fight fairly quickly, and if he's hit hard-but-not-hard-enough, his recovery is easy to predict and we can finish him from there. If we're at 100 and he's at 50, a bair or forward smash will be all we need to force him to respect our offstage options and suddenly the match is in our favour. It's landing those moves that's the trick, though.
tl;dr:
Falcon is way too fast for us in the early game. We both have pretty decent low-percentage combo games but I think ours is slightly better (or at least we can hit more times than he can). He's difficult to approach from any angle and our zoning tools are generally too weak to force him away until we're in kill percentage. Even then, his blinding speed and powerful aerials make it easy for him to catch us off-guard regardless.
Like all match ups, it starts to turn in our favour once our Aura gets higher, but that depends on whether you've been keeping him at least halfway up with your own percentage. While our moves hit so hard that it forces him to respect us, he moves so quickly and hits hard enough that it might not even matter if we mess up. He is easier to edgeguard than we are, but his edgeguards are more devastating than ours.
I'd argue it's an even 50-50, if not 55-45 Falcon.
