With the 3DS version out soon, we're gonna get a huge influx of new information on what changed with Lucario from smash 4, I'll be updating this OP on all the information that is 100% confirmed to have been changed or is the same. If you have any information that is confirmed, provide a link to the evidence and posts that confirm something is the same or is change.
Aura has been buffed for how much it influences him compared to Brawl, moves seems to scale differently with aura in terms of knock-back and damage.
His smash attacks have been claimed to be faster.
He skins are green, purple, dark gray, and the rest are shades of blue.
Jab is the same in terms of knockback, the animation and hitbox is slightly differently. Might be slightly harder to link the whole thing together.
Still not affected by Aura. Seems to kill pretty decently. Lag seems to be mostly the same from Brawl, it doesn't have the follow up potential it had in Brawl it seems, not sure needs more testing.
Is a forward swipe, not a double hit poke anymore. It can be angled.
Seems pretty much the same from Brawl.
Same as Brawl mostly, still is very fast. Has some good kill potential.
A lot of changes here. It's faster overall, still hits like a truck. It doesn't linger anymore and doesn't hit behind him.
It's a little buffed this time, faster start-up a little less reach, but it sucks people into the strong hit. Also kills at lower percents.
Same as Brawl in animation, comess out faster, kills faster, and it has more range. Yeah just overall a straight buff.
Only thing changed is that his whole body is not a hitbox anymore. Pretty much the same.
Doesn't stall like in Brawl, less range. Still functions like Brawl just those two main changes.
Fair strings still possible, it's harder to follow up this time since some characters need you to use your double jump this time now. Less carry off potential.
Different animation but still the same as Brawl's overall.
Still Aura sphere from Brawl with a new visual to it, It travels faster in both forms and is closer to the ground. At max Aura it kills lighter characters at 60%.
Still Force Palm from Brawl with what looks like a slightly new visual to it, The whiffed Force Palm seems to do more knockback than in Brawl grab hitbox is smaller than before. Falling behind someones shield and doing the frame 8 aerial grab still works like in Brawl.
Still the same from Brawl visually His Extreme Speed now scales with Aura on Distance. It has a hitbox at the end of the UpB. The movement curving is even stronger.
Same as Brawl with updated visuals. Damage and Knockback still unknown.
Dunno right now seems the same.
Seems the same from Brawl.
Seems the same from Brawl, except now scales with Aura.
Seems the Same from Brawl.
Seems the same from Brawl, except now scales with Aura.
Changed from Aura Storm to Mega Lucario. Instead of shooting a large Kamehameha Lucario will now transform into Mega Lucario where his Aura is at Maximum power.
Same.
Same.
Same.
Overall: He seems like he got a few nerfs but was straight buffed overall.
