This intergalactic bounty hunter's full name is Samus Aran. Clad in a Power Suit made by the Chozo race and infused with their enhanced blood, she cleared the planet Zebes of a Metroid infestation. Samus is an orphan, the sole survivor of a Space Pirate raid that destroyed an Earth colony named K-2L.
Samus Aran [Smash 1]
Samus has an abundance of projectile weapons, making her a long-distance attack specialist. The most powerful weapon in her arsenal is her Charge Shot, but be warned: it can be reflected. Her missiles have homing capabilities, but when fired as Smash Attacks, they fly on a straight trajectory and have boosted power.
Samus Aran [Smash 2]
While Samus's arsenal of missile weapons is indeed formidable, her enemies are in for a rude awakening if they guard against nothing else. Her Grappling Beam captures foes and latches on to walls, and the Screw Attack drags foes upwards in a series of spins that doubles as a recovery move. Samus can also use her bombs to perform Bomb Jumps.
It's said that the orphaned Samus Aran was raised by the few survivors of the Chozo race. They armed her with a Power Suit and taught her the ways of advanced combat; even burdened with her heavy suit, Samus is as graceful as a butterfly. In the Metroid series, it was standard that Samus would remove her helmet and armor if you cleared the game fast enough.
A boss enemy from Metroid. Kraid lives in the depths of Brinstar. He immobilizes enemies with his three red eyes, and his powerful jaws can crush anything. He can also shoot the three spikes in his belly; it's said he often fires them at his prey. Once Samus defeated Ridley and Kraid, the way to Tourian opened.
The head of the Space Pirates on Zebes, Ridley soars through space on wicked wings. Ridley may look like a mindless monster, but he's actually quite intelligent. After the SR-388 incident, where Samus captured the infant Metroid, Ridley took the Space Academy by storm, annihilating the complex and taking the Metroid back.
A parasitic life form that can absorb all types of energy, Metroids have strong resistance to most conventional weaponry. To defeat them, Samus Aran had to freeze them with Ice Beam shots and then blast them with missiles. Mochtroids, which look like Metroids, are weaker, with fewer internal nuclei.
These statues, which provide power-ups to Samus and have some connection with her Power Suit, have been found in many places, most notably Zebes. The Chozo boasted the most advanced civilization in their galaxy. Some say that when they could advance no further, they chose to withdraw and observe other life forms.
One of Samus Aran's power-ups from the original Metroid, the Screw Attack turns a jump into a rotating attack move. When carrying this item, any character's ordinary jump move will turn into a Screw Attack. By the same token, if you throw this item at an enemy, your foe will spontaneously do a Screw Attack.
This compact ship is used by Samus as her base of operations. Of course, Samus can't fly it into the catacombs of every planet she visits, so she leaves it on the surface as her sanctuary. Samus can recharge her Power Suit inside the ship, so it tends to be the only safe and secure spot on inhospitable alien terrain.
