The Gravity Suit (Gravity Feature in Metroid: Other M) is an upgrade for Samus Aran's Power Suit. As its name implies, the Gravity Suit is known for negating gravitational effects such as zero gravity in space. The Gravity Suit enhancement is obtained after the Varia Suit; the addition turns sections of Samus’s armor purple, reduces the damage she takes, and allows her to move in fluid unhindered by the resistance and pressure it would normally exert. In Metroid Prime, the Gravity Suit also enhances the visor so it can give a better, clearer view while underwater. In Super Metroid, Metroid Fusion and Metroid: Zero Mission, the Gravity Suit also negates damage sustained from contact with magma. In Super Metroid, Metroid: Other M and Metroid: Zero Mission, it is the final suit Samus acquires.
The Gravity Feature in Other M works like the Hazard Shield in Metroid Prime 3: Corruption, in that the Power Suit is covered with an aura when the upgrade is used on certain environments. There is also an aura depicted around the Varia Suit in artwork in Metroid 's manual, and the Phazon Suit emanates an aura.
In Metroid Prime 2: Echoes the benefits of the Gravity Suit are instead granted by the Gravity Boost accessory. [Source: wikia]
