Rosalina
B - Wand wave - Creates a shield that can reflect projectiles
Up B - Launch Star - Rockets up in a launch star, gaining height and damaging those in way
Down B - Cosmic shield - creates a shield that can absorb projectiles and restore health
Side B - Luma - A little Luma appears that can hamper enemy movement (kind of like Pikmin, but it slows your opponent instead of damaging them)
Final Smash - Comet Observatory - Rosalina boards the Observatory (which is transformed) and unloads laser on the field (somewhat like Snake's final smash)
King Smithy (with Tank/Warlock/Box heads) like Pokemon trainer
B - Hammer/Magic/Head strike - standard heavy attack
Up B - Chandelier grab - A chandelier appears above Smithy and he grabs it to reach greater heights
Down B - Smith - turning into one of his other three forms
Side B - Motor/Fireball/Lead ball - projectile
Final Smash - Exor - Exor falls from the sky and asplodes the entire area, instantly KOing those too close, and damaging the others
Assist Trophies
THE BOSS - Runs around screen firing her Patriot, final unload will KO the target hit
Axem Rangers - Dash around the screen like Latias/Latios- then they board their ship and charge thru the middle of the level
(BTW, those Miyamoto animations are hysterical)
