Samus Aran’s infusion with Chozo DNA, as well as her warrior training since her childhood, has turned Samus in a superior athelete. Her training began at the age of 3 and continued up until she was 14 years old. As a result of the Chozo’s influence, Samus is capable of running and jumping heights far past normal human ability, as well as surviving falls that would otherwise kill an ordinary human. Samus is also more adaptive to foreign alien environments that humans cannot survive in. For example, she was able to breathe normally without her Power Suit on Elysia, despite the atmosphere being toxic to humans. While Samus does not exhibit any powers that humans do not naturally have (except possibly the aforementioned capability of surviving foreign alien environments that humans cannot survive in), all of the normal human limits have been exceeded to the max.
Samus gains an additional boost of power, in addition to the upgrades it provides, as seen in this Metroid: Other M art.

Samus also demonstrates good sharpshooting skills. She is an excellent marksman, with incredible aim, and is tremendously deadly in combat. She exhibits prodigious puzzle-solving and hacking skills. She also possess a limber figure that allows her to crawl through tunnels and gaps that would normally require usage of the Morph Ball. All of these are, of course, augmented further by her Power Suit. If need be Samus will engage in physical combat, often using kicks and wrestling tactics to weaken her foe for a point-blank shot.
The extent of Samus’s training after she joined the Federation Police is currently unknown, but it is clear that the Federation has made one major augmentation to her abilities: her infusion with Metroid DNA. This infusion was done in a last-ditch attempt to save her life after she was infected with the X Parasite, and thus it was not completely known at the time what the side effects would be. As a result of the infusion, Samus gained immunity to X Parasites, but also inherited the Metroid’s crippling weakness to cold, though this disability could be canceled out with a later Varia Suit upgrade. She does not seem to have inherited their ability to float, and still relies on the Space Jump to do so. It is currently unknown whether Samus has inherited the Metroid’s signature ability to leech life energy from other lifeforms, aside from the well-documented X Parasites, though this is likely to be solved in any sequels taking place after Metroid Fusion.
Samus’s most notable piece of equipment is, of course, her Power Suit, which has become virtually synonymous with her own identity. This suit was given to her when she first began living with the Chozo, and was built to be fused with her mind, body, and soul. The original Power Suit was destroyed when Samus crash-landed on Zebes after an ambush by Space Pirates, but her duel with the Chozo Hieroglyphic gave her a new, upgraded suit, which is able to absorb dozens of upgrades of alien origin. The Power Suit's main purpose is to protect her from adverse environments and enemy fire. The suit itself can be upgraded to such dozens of other forms, each with its own different advantages. While some suits are stronger than others and have different abilities, all they all maintain the same basic shape and usage.
Beneath the Power Suit, Samus wears a skin-tight body suit known as the Zero Suit. Because of its negligible weight, this suit allows Samus to perform at top physical performance level, and gives some, albeit weak, protection from enemy fire. She also owns a pistol known as the Paralyzer, which auto-charges to fire stunning shots, though unfortunately, it has no lethal capacity.
For transportation, Samus uses her Gunship, which usually resembles her helmet. She has owned a single Gunship that has been with her since her very first Zero Mission and remained in her possession until its destruction in Metroid Fusion. It is a Hunter-class starship made especially for her by the Galactic Federation on Aliehs III. Two other gunships are also shown in Metroid Prime 3: Corruption and Metroid Fusion.
http://metroid.wikia.com/wiki/Samus_AranSolid Snake was a product of a lab experiment "Les Enfants Terribles" ("The Terrible Children"), and "born" in 1972. He received the recessive of the genes from his "father", an ex-black ops soldier called Big Boss whom he killed. His "brother" Liquid Snake received the dominant genes, and Liquid is now the primary antagonist of the series of games. While Liquid fights for Big Boss' vision of total military control, Solid Snake is always fighting for the good of the people and does not consider himself to be heroic or legendary (though other characters in the games believe him to be).
Solid Snake is very skilled with a wide variety of weaponry and close quarter combat (CQC). Some of these weapons include but are not limited to:
Beretta: M92f Tranquilizer (suppressor attached)
HK: Socom Mk23 pistol (suppressor can be attached)
Saint-Étienne Arms: FAMAS full auto rifle
Colt: M4 select-fire rifle
HK: PSG-1 (and alternate TSG-1 Tranquilizer) sniper-rifle
Raytheon Missile Systems: FIM-92 Stinger Missile Launcher
Nikita Missile Launcher (fictional)
Grenades (frag, chaff and stun)
C-4 Explosives
Claymore Mines
