Samus, Dark Samus, & Sa-X

Samus Aran: Samus Aran is slender and light-skinned with a muscular physique under the armor, though her superhuman abilities may be accountable to her muscle/bone density given her hybrid genetics and augmentations. Her hair color is blonde, her eye color is blue, and fair skin. Samus typically wears her blond hair in a modified ponytail with a red hairband, with a lock on either side.

She is 6 feet 3 inches tall (roughly 190 cm) and weighs 198 pounds (roughly 90 kilograms)

She has two normal suits she wears when on missions: Power suit: The suit Samus normally wears on missions. It is entirely golden yellow, with the exception of the helmet, which is red, her arm cannon, which is light blue, and her visor, which is light green.

Samus' Power Suit comes with a standard Power Beam and the Oxygen Supply Equipment allows her to survive almost indefinitely underwater and in outer space, including the ability to resist most airborne toxins. Its basic functions are not always sufficient for a busy Bounty Hunter, so the Chozo used a modular construction allowing the suit to be outfitted with a wide variety of weaponry and additional armor, as well as many additional upgrades

On its most basic level, the Power Suit contains 99 units of energy that sustain it. This amount is increased by 100 whenever Samus acquires an Energy Tank, but if completely drained, it becomes unable to protect Samus. Thus, she is forced to revert to the Zero Suit, a blue bodysuit that grants weaker protection and is equipped with a stun pistol, the Paralyzer.

While active, the Power Suit bonds with Samus biologically and cannot be taken off without her cooperation. It has been observed on many occasions that the method which Samus uses to remove the Power Suit is to have it dematerialize with a bright flash. However, the helmet can be removed manually.

Samus' Power Suit requires superhuman levels of concentration and mental determination to operate efficiently. Due to years of training with the Chozo, Samus learned how to control her emotions and maintain the Suit's use for long periods of time.

The suit’s various upgrades include: Varia Suit - Reduces damage taken and protects Samus Aran from extreme heat. Gravity Suit - Negates extreme gravitational effects around its wearer, such as zero gravity in space.

The suit can also fire various beams, including: Power Beam - Also known as the Normal Beam, it is the default weapon made of Chozo technology and is the most basic beam in Samus' arsenal. Charge Beam - Allows Samus to charge up her current beam and release a more potent version of it. Long Beam - Extends Samus' shots to be capable of traveling much farther. This upgrade also slightly increases the strength of the Power Beam. Wave Beam - Allows Samus' shots to pass through walls. It also fires in a sine wave shaped flight trajectory. Ice Beam - Allows Samus to fire a potent beam that has the power to freeze most enemies. Plasma Beam - Allows Samus to fire a thin ray capable of piercing multiple enemies.

The Power Suit also allows for a Missile Launcher upgrade, which allows Samus to fire missiles. She can hold up to 5.

Morph Ball - Allows Samus to transform into a sphere that’s 0.8 meters in diameter to traverse across tiny spaces she wouldn’t be able to normally. Her main attack in this form is releasing bombs

Grapple Beam - An electrical or magnetic beam weapon with tethering properties. It is used to latch onto certain surfaces, allowing Samus to swing from this point and reach areas that would be otherwise unreachable

Zero Suit - A full body suit, mainly light blue with some darker blue highlights on it. Made out of some sort of firm polymer, it allows Samus to stretch in different positions while still holding together. The Zero Suit appears to be indestructible or at least very sturdy, as it is never visibly torn or damaged by enemy attack. While it does heavily increases her mobility, her vulnerability becomes near null, taking damage at a higher rate.

Samus has also been merged with Chozo DNA, which allows her to adapt to harsher conditions and gives her speed and agility beyond the capability of ordinary humans.

Samus is a heroine of few words, and a fearsome warrior. She remains quiet, humble, and solemn despite her great accomplishments, and has devoted her life to maintaining peace in the galaxy. Her main enemies are the Space Pirates. Despite her tragic origins, Samus has been shown to have unparalleled willpower and resourcefulness, succeeding where thousands failed and stopping at nothing to save the galaxy from any threat that may arise

Although Samus works for the betterment of the galaxy and frequently collaborates with the Galactic Federation, she is a lone wolf at heart, only accepting their orders due to their common goals and bounties. She has little respect for authority and dislikes being told what to do, only allowing such supervision from those she trusts such as Adam Malkovich, and rejecting others such as Raven Beak or even the Galactic Federation when their goals no longer intersected with hers.

Despite her reputation for combat, Samus is also known for her compassion, and has consistently stood up to secure the helpless and downtrodden.

Witnessing her parents' deaths at the hands of Space Pirates left Samus with PTSD, that one rarely rears its ugly head in both combat and dreams, and the occasional talk with a trusted confidant.

Dark Samus: As implied by her name, Dark Samus was an evil Doppelgänger of Samus Aran in her Phazon Suit. She is an exact replica of Samus, though composed mainly of Phazon energy, and is comprised of mainly blues and black tones.

Dark Samus, as her name implies, was shown to be cold, calculating, sadistic, and utterly merciless. The lives of her opponents held little to no value to her, and she never hesitated to use her allies to her own gain. Normally, the only people she does kill are those that are in her way, otherwise, she ignores them completely

As Dark Samus, the creature utilized many abilities similar to Samus, in more powerful forms. She could fire two types of Phazon beams at enemies in the form of either a continuous stream of small shard-like bursts, or a thin laser Beam which she shot in an arc. She also possessed the same missiles that Samus does.

She also has an attack that can spread out to freeze her energy, can do a powerful dive bomb attack, transform into a morph ball, and can render herself invisible.

Dark Samus’ power is generated by Phazon, a radioactive material: the more she has, the greater the energy level. However, if she consumes too much Phazon, it could overload and destabilize her if used at that state.

SA-X Owing to it having copied Samus's Varia Suit, and to a lesser extent DNA from Samus herself, the SA-X is a near-perfect duplicate of Samus Aran herself. The only noticeable difference between the SA-X and the actual Samus is that the SA-X’s eyes are completely blank: white with no pupils. Despite the lack of pupils, SA-X can still emote quite well, making it clear how she feels in a certain situation

As SA-X comes from the X Parasite mimicking Samus, the X Parasite pretty much is based on pure instinct alone, having nothing that could be truly considered a “personality”. She can still communicate in English.

SA-X’s powers is exactly the same as Samus’, having the exact same physical attributes and strengths, the exact same weapons, and the exact same mindset and strategies.
