Power Suit

The Power Suit is a coating of lightweight armor designed by the Chozo, a race of intelligent bird-like creatures from the Metroid games. It is most commonly worn by the franchise's main protagonist, Samus Aran, a female bounty hunter raised by the Chozo.

Varia Suit
The Varia Suit is an upgraded version of the original powersuit, providing much more protection, especially against extreme heats and low-temperatures, and reduces damages from acid and other attacks used by the hostile creatures Samus encounters on her journies. Speed is also increased. It appears in all Metroid games to date, including the original one, its remake, all three Prime games included Pinball, Metroid II, Super Metroid, Other M, and Fusion.

Phazon Suit
The Phazon Suit, seen only in the first Prime game, shifts the original yellow and red color scheme to black and maroon, supplying Samus with 75% damage reduction and fierce protection against Phazon beams. It was gained by the galactic bounty hunter after she beat the Omega Pirate and accidentally had his slump body fall on her, flooding and corrupting the Power Suit's systems with raw Phazon.

Zero Suit
The Zero Suit is in fact not a collection of armor, but a skin-tight turquiose jumpsuit that covers all of Samus' body excluding her head. It is worn underneath the Power Suit and appears in Zero Mission, Prime Hunters, the last two Prime games, and Other M. Though it provides no defense whatsoever, its properties lie within agility boost. It allows Samus to run much faster, crawl, jump higher, and slight. It also arms her with the Paralyzer, a stun-gun like firearm.

Gravity Suit
As the name suggests, the Gravity Suit negates the effect of both gravity, water resistence and extreme environment, and substances such as magma. It also triggers the speed booster and jump upgrades to have to ability to work in liquids. It appears in the first Metroid's remake Zero Mission, the first Prime game, Super Metroid, Other M, and Fusion.

Features
The Power Suit provides medium residence against any forms of attacks, heat, and underwater enviroments as well as the vacuums of space. It also enhances Samus' already high amounts of speed, agility, and strength. The green translucent visor provides a Heads-Up-Display (HUD) that can scan creatures and pulls up a digital file about them, shows a heat tracking radar, Samus' current weapon's ammunition level, and her health. The suit also always contains a built in arm cannon on the right hand instead of a padded yellow glove like on the left arm.
