Samus Aran has fought her way across a variety of planets in the Metroid series. She wears a Power Suit designed by the Chozo, giving her incredible versatility in a fight. She can wade in, but she favors beams and missiles. A fully charged Charge Shot packs a serious punch!”
Samus Aran is the main character from the Metroid series. She was raised by the Chozo, an ancient race of bird-like people, and goes through dangerous missions throughout the galaxies, such as saving planets and bounty-hunting. She appears in Kirby's Dream Land 3 as a cameo, and is a playable character in the Super Smash Bros. series alongside Kirby.
In Kirby's Dream Land 3, Samus Aran appears in cameo, she wants Kirby to exterminate a horde of Metroids in exchange for a Heart Star. The Metroids can only be defeated using the Ice ability, a reference to how they are destroyed in the Metroid games.
In the Super Smash Bros. series, Samus is a starting playable character in all five games. She hails from the Metroid series as the first and only playable character of it (not counting Zero Suit Samus, as she is just Samus without her powersuit and its moveset). She has projectile attacks such as her Charge Shot and Missiles that cover a wide range of space.
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 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.”

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.”

The intergalactic bounty hunter named Samus Aran. Orphaned at an early age, she was taken in and raised by the alien race known as the Chozo. The Power Suit she wears is a product of their technology. Her unique combat skills combined with her athleticism and Arm Cannon have seen her through countless missions.”
Samus Aran without her mighty Power Suit. In this condition, she does not have the firepower she's famed for but is in full possession of the agility and athleticism she gained through her childhood training with the Chozo. Without the armor, she's also much, much faster. The weapon she carries is a self-protection device known as a Paralyzer that stops enemies cold.”

Samus protects herself from overhead enemies with her up smash, Cover Fire, which can land multiple hits on anyone it connects with. Samus also fires a homing missile by holding sideways and pressing the special- attack button or launches a Super Missile by quickly tapping sideways instead.”
Samus is far from helpless when her Power Suit is deactivated. Sure, she loses a lot of the moves and weapons she had access to before, but her Jet Boots pick up the slack! She also has the Paralyzer, a versatile weapon that can shock her rivals or change into a Plasma Whip to grab edges and enemies.”

Zero Suit Samus's up special Boost Kick involves a series of fast kicks that end with a swift, sideways-launching one. A perfectly executed attack will hit eight times! Her down special Flip Jump can bury a grounded fighter in the dirt. She can kick midflip by pressing the special button.”

One entire stage in Iceberg that revolves around having to defeat all the Metroids in Kirby's Dream Land 3 is a reference to Metroid II: Return of Samus, where Samus' mission is to destroy all the last Metroids on SR388. She rewards the player with a glimpse of her helmet off, and because all the Metroids in the area have been exterminated, her mission is complete. In the Metroid games, when all of the items are obtained fast enough, the reward at the end is seeing Samus without her helmet or even her whole suit. This is basically the same concept.
During her cameo appearance in Kirby's Dream Land 3, she appears approximately twice Kirby's height. Samus is about 6'3'', therefore Samus likely either is considerably shorter in this appearance or may have been scaled down so that she would not look out of place in Kirby's world.
A treasure in The Great Cave Offensive, the Screw Attack (misnamed "Screw Ball" in the English version of Kirby Super Star), is an item Samus equips in the Metroid games to be able to spin rapidly in the air, reaching many places and destroying enemies upon contact.
