Galadriel has very strong magical powers, and she is said to be the greatest of the Ñoldor after Fëanor. The majority of her powers come from her Ring of Power, Nenya, the Ring of Water.
She is described as "the mightiest and fairest of all the Elves that remained in Middle-earth", and the "greatest of Elven women". Throughout the Third Age it was unknown who wielded the Three Rings, but during the War of the Ring, Galadriel revealed to Frodo Baggins that she was the bearer of Nenya.
Additionally, while he was in his weakened state, Galadriel could hold him off through the power of will alone. However, if Sauron had his One Ring and faced off in a battle against Galadriel, it's unlikely that there would be much she could do.
She has an ( empathic power to read other people's souls) and perceives the darkness within! She used the power of the water ring to create an earthly paradise on earth, but after she went on her way the paradise was ruined!
She also resisted being offered the ring of power by Frodo following his vision in the mirror of Galadriel, an immense test given the ring's seductive powers. Yet Gandalf's power level exceeds even that of Galadriel, as shown by his rebirth in the Two Towers.
Why Was Galadriel so Powerful? Middle-earth Explained
What was Galadriel's gift to Aragorn?
Galadriel then presents the Fellowship with additional gifts. To Aragorn she gives a sheath for his sword, Andúril, and a green gem in a silver brooch. Boromir, Merry, and Pippin each receive belts of silver or gold, while Legolas receives a longer, stouter bow.
In his notes, Tolkien remarks that Sauron saw Galadriel as his equal. Add that to the fact that she's untrusting of Sauron (yes, even when he's in his Annatar guise) and an unwavering, single-minded force, and it's more likely than not that Sauron feared Galadriel — or the potential she held to upend his plans.
Though neither is someone you'd wish to annoy, Galadriel is generally considered more powerful than Elrond in Lord of the Rings. Not only is she older than her Rivendell counterpart, but Galadriel witnessed the light from Valinor's Two Trees, giving her a mystic quality.
For those that haven't read Tolkien's work, it's easy to see why many audiences suspect Gandalf and Galadriel are in love. After all, many of their interactions in The Hobbit trilogy practically scream romance. However, their relationship remains purely platonic in Tolkien's source material.
Through her great-grandmother, Idril, Arwen was a descendant of King Turgon of the Noldor. Through her mother, she was the granddaughter of the Elf-queen Galadriel of Lothlórien. Through both of her parents, Arwen was a direct descendant of the ancient Elven House of Finwë.
Fans know from the later Lord of the Rings and The Hobbit tales, that Galadriel eventually finds, falls in love with, and marries Celeborn, the elf who accompanies her down the stairs when the fellowship first arrives in Lothlorien.
Thus, Galadriel's dark form in Jackson's The Lord of the Rings personified what would have occurred had the Lady of Lothlorien given in to temptation and taken the One Ring for herself. She would have succumbed to evil because the Ring was indomitable, even with her power.
Galadriel, one of the greatest Elves of Middle-earth, could resist the temptation of the One Ring because of her exceptional strength of will, wisdom, and awareness of the Ring's corrupting influence.
Sauron's deepest fear was that Aragorn would use the Ring against him. With its powers of domination, Aragorn could comfortably take over the entirety of Sauron's dark army. Though this would eventually corrupt Aragorn, it would allow him to destroy Sauron and take his place.
The outcome was that Galadriel was able to penetrate Sauron's mind and issues a single command "Go back to the void from whence you came!" Unable to resist her any longer, Sauron screamed and fled, but Galadriel was rendered weak after their strife and fell back, Elrond rushing in to support her.
Halbrand does not deny his heroism out of bashful humility, though; he knows that as Sauron, he's not the hero she wants him to be for the Southlands -- not when his plans involve scorching it into Mordor. No, Halbrand was never a hero, nor did he ever claim to be.
Defeated by the Host of Valinor in the War of Wrath, Morgoth was banished from Middle-earth into the Timeless Void, though it was prophesied that he would one day return.
The outcome is that Galadriel is able to penetrate Sauron's mind and issues a single command "Go back to the void from whence you came!" Unable to resist her any longer, Sauron screams and flees with the Nine.
In The Hobbit they are called the dark elves (dark because they never saw the light of Aman), the light elves (having seen the light of Aman),and the sea elves. Legolas was a dark elf, Galadriel was a light elf; so there is no relationship between them.
Before the Company of the Ring left Lothlorien , Galadriel presented each of them with gifts: "To Legolas she gave a bow such as the Galadrim used. The bow was longer and stouter than the bows of Mirkwood, and it was strung with a string of elf-hair". The gift was accompanied by a quiver of arrows.
Arwen. Galadriel's granddaughter and the daughter of Celebrían and Elrond. After the War of the Ring, Arwen marries Aragorn II Elessar and becomes Queen of the Reunited Kingdom of Arnor and Gondor. Like other Half-Elves, Arwen has the birthright to choose either immortality among the Elves or mortality among Men.
