Launch Star (move)
From the Super Mario Wiki
Launch Star is Rosalina's up special move in Super Smash Bros. for Nintendo 3DS / Wii U. When Rosalina uses this move, a Launch Star appears and sends Rosalina into the air at an arc, similar to the Launch Stars from Super Mario Galaxy and Super Mario Galaxy 2. The angle she travels at can be adjusted by tilting the Control Stick or Circle Pad, though the move itself deals no damage. The Launch Star itself is multicolored instead of one single color, and the small orbs at the end of its points have been removed.
Like with other characters' special moves in Super Smash Bros. for Nintendo 3DS / Wii U, two custom variants for this move exist:
Launch Star Plus fires Rosalina at a much faster rate, but the player can't control its angle, which offers more vertical distance than horizontal.
Launch Star Attack sacrifices travel distance to allow Rosalina to damage opponents with her body, and ends with a move that's similar to her neutral aerial attack. However, the move does halt her momentum upon ending, and it can't travel straight up.
