Rosalina moveset:
B: Star piece: She throws out one of thse star peices. They can be aimed, and do not disappear like Fox's blaster, but they moves slowly like something would in space They do break when they are hit though.
^B: Zero Gravity: Her third jump allows her to hover, but unlike peach she hovers for a shorter time, and can move 360 degrees. Her A moves can be used in this state, but not her B moves.
vB: Star trap: You know those things in Mario galaxy that act like cannons and blast you places? Well using this move will cause one of these to pop up. on the ground they are at an angle, so they will shoot the opponent, causing them to fly through the air in a "rainbow" type of pattern. If used in the air, the cannon will shoot them towards the ground.
B>: Luma dash: Rosalina flicks her wand and Luma dashes forward a few feet, and swiftly returns to her side. Think ZSS's B>, but slightly higher in the air, (unless she is ducking) and a Luma!
