With her additional Chozo DNA, Samus is physically faster and stronger than other augmented humans, and is more flexible as well. She is also capable of survival in higher gravity and slightly more durable in hostile environments. Her Power Suit pushes these innate talents even further, and allows her to curl into a 1 meter tall sphere form called the Morph Ball for more mobility.

Power Suit- Samus's Chozo armor is capable of equipping various upgrades, including a layer of heat protection, letting her traverse high temperature areas and walk through lava (until it eventually wears down her shields). It comes with a computer visor for scanning objects and a breathing system for underwater, space, and toxic environments. The power suit is integrated with her body and mind and can be assembled and disassembled in a flash, though can't be removed against her will unless it takes too much damage.

Zero suit- A thinner layer of clothing she wears beneath her neurologically connected armor. She's much faster without her outer shell, but her defenses are weakened. She uses a paralyzing pistol/whip when unarmored, but it's non-lethal.

Arm Cannon- Used to fire her basic Power Beam. It can be charged to increase its power, and has a variety of upgrades including ice, a wider wave blast that passes through walls, a plasma beam, and a beam that acts as a grappling hook.

Missiles- Samus can switch to these more powerful exploding projectiles, though she has limited ammo.

Bombs- In Morph Ball mode, she can drop these smaller charges to stun enemies and destroy obstacles. Power Bombs are an upgraded version that have a much wider radius. 

Screw Attack- Samus curls up and somersaults while giving off a deadly energy, turning into a charged ball that damages enemies on contact.
