Mister Sakurai has been enjoying the fact that he gets to show Lucario off now!
From what it looks like, he’s just showcasing the things Lucario can do, and it looks like he may have the same move set that he did in Brawl. In SSBB, his normal smash was the aura sphere that we were given details of yesterday. This is his ExtremeSpeed, as told by Sakurai, which was his up smash in Brawl. Just my opinion, but I hope Sakurai will change Lucario’s final smash, at least. I would like to see him mega evolve as a final smash!
