Gravitational Pull (move)
From the Super Mario Wiki
Gravitational Pull is Rosalina's down special move in Super Smash Bros. for Nintendo 3DS / Wii U and Super Smash Bros. Ultimate. The move is based off the spin move from Super Mario Galaxy and Super Mario Galaxy 2. The Star Cursor from the Super Mario Galaxy games also appear. The move itself does not cause any damage, but it has several properties. First, it draws in any items close to Rosalina, enabling her to use them more conveniently. Gravitational Pull also protects Rosalina from most projectiles and thrown items; if an item is thrown at Rosalina, its effects will be disabled by the move; all other projectiles vanish. Gravitational Pull also draws in any loose Lumas, but it doesn't stop explosives (such as Bob-ombs) from self-destructing. In Super Smash Bros. Ultimate, Gravitational Pull can not only pull items, but also equip items.
As with all special moves in Super Smash Bros. for Nintendo 3DS / Wii U, Gravitational Pull has two counterparts that can be used instead once they are unlocked:
Catch & Release enables Rosalina to draw in fighters and damage them, but it doesn't protect her from items and projectile attacks.
Guardian Luma enlarges Luma, which not only protects Rosalina for some time, but it can also damage any opponents who come into contact with it. The move can also attract items, but with a shorter range.
