New moveset, this one a blatant Street Fighter Rip:
^B: Sky Uppercut (dragon punch)
>B: Iron tail (Helocopter kick)
B: (?)
vB: Aura Sphere (Hadoken) (diagonal down while in air)
Not bad, but here's another one to consider (not an SF rip that I know of):
^B: Sky Uppercut (gonna stick with it)
>B: Bullet/Mach Punch (quick side dash...similar to Fox's, but hey, it's one move...)
vB: Dark Pulse (small wave of dark energy radiates from Lucario)
B: Aura Sphere (something tells me this is the best place to put it...and unlike Shadow Ball, AS would follow the closest opponent, but be weaker than SB)
Final Smash ideas:
FS 1: Close Combat (works like Link's...attacks the nearest opponent)
FS 2: Psychic (picks up, shocks, and throws all opponents in a certain range)
FS 3: Dragon Pulse (sends a huge wave of dragon energy across the field...could be like a stage-wide version of Bowser's flame breath)
