Alright, for all the move disscussions.
B: Aura Sphere is obivous, his sig move, makes sense
B>: I believe it to be Force Palm, i have seen nothing better suggested but that does not explain the grab at close range
B^: appears to be Extremespeed, he is one of the six pokemon who can learn it. extremely (haha no pun intended) likely to be extremespeed. he can learn agility but only though an egg move.
Bv: Counter/Reversal/Me First/Whatever you want to call it. This move makes you move behind your oppenet and strike. none of these moves match up that well.
Counter takes a hit and deals back twice the damage.
Reversal does more damage with less health.
Me first if faster uses the oppents offensive move at one and a half strength
Final Smash: Flash Cannon/Focus Blast/Dragon Pulse/Hyper Beam/Super Aura Blast
ok its a big beam compareable to DBZ. it is clearly shown coming from his hands.
Flash Cannon is an attack with an orb of light
Focus Blast is also an orb of energy attack
Dragon pulse while it is a beam, it is clearly shown and stated that is comes from the mouth
Hyper Beam also a beam, while it has often been shown as a coming from the mouth, some pokemon have been shown chrageing it in their "hands". It is just one of the many possibilies.
I think it is hyper beam but this is mostly based off of the incositencies of the other often suggested options. it is also based off of this comparison of pictures. Lucario's final smash and deoxys from a pokeball using hyper beam. I say they look very similar.
