Thranduil is a fictional character in J. R. R. Tolkien's Middle-earth legendarium. He first appears as a supporting character in The Hobbit, where he is simply known as the Elvenking, the ruler of the Elves who lived in the woodland realm of Mirkwood.
Tauriel was a Silvan Elf of Mirkwood. She has been described as a warrior and head of the Wood-elf guard. Her character was invented by Peter Jackson and Fran Walsh for The Hobbit (film series) and was portrayed by Evangeline Lilly.
TL;DR: Thorin is half-elf, and Fili and Kili are themselves both part elf and half-human. The two young dwarves represent the union of Elves, Men, and Dwarves that once existed before Dale fell, and which will rise again.
Bilbo-Bungo-Mungo-Balbo Baggins, same as the one mentioned above. In the LOTR, what does it mean by Bilbo and Frodo being "elf friends"? It means that Bilbo and Frodo were Elfophiles. They studied elf lore, and their language, history and culture and were fascinated by them.
Tauriel admits her love for Kili in The Hobbit: The Battle of the Five Armies. Tauriel leaves Thranduil and accompanies Legolas and Bilbo to Ravenhill in order to warn Thorin, Dwalin, Fili, and Kíli of an upcoming attack led by Bolg.
Tauriel truly threw a wrench in Legolas' life when he fell in love with her. She was brave, fierce, and a protective leader of the guard. He was meant to be the dutiful son of King Thranduil, but in loving her, he became a stubborn, masterful archer instead.
Pace stars as Brother day, the current Emperor of the Galaxy. He is known for starring as Thranduil the Elvenking in Peter Jackson's The Hobbit trilogy and as intergalactic villain Ronan the Accuser in the blockbuster Marvel film Guardians of the Galaxy, a role he reprised in Captain Marvel.
The Elves (Quendi) were the first of the races of the Children of Ilúvatar, known also as the Firstborn for that reason. The Elves are distinguished from the other two races, the Men and the Dwarves, especially by the fact of their near immortality.
Legolas does not marry or have any children, based on the appendix of The Lord of the Rings. Regardless of who his mother was, Legolas is the last of his line. When he sails into the West at the beginning of the Fourth Age, he leaves no family members behind.
The townsmen's arrows and spears proved useless against the dragon's armoured body. The thrush told Bard the Bowman of Smaug's one weak spot, a bare patch on the dragon's belly. With his last arrow, Bard killed Smaug by shooting into this place.
The first Elves to awaken were three pairs: Imin ("First") and his wife Iminyë, Tata ("Second") and Tatië, and Enel ("Third") and Enelyë. They walked through the forests, finding other pairs of Elves, who became their folk. They lived by the rivers, and invented poetry and music in Middle-earth.
Elrond is actually half-elf and half-human, though he has chosen to live as part of elvish society. He is the Lord of the Elves in Rivendell and he used to be a great warrior.
In The Hobbit, Thranduil is the Elf King and father of a key player in the war of the ring, Legolas. As a king he takes his rule seriously, fighting for his people and trying to keep them alive at all costs.
In Peter Jackson's Lord of the Rings and The Hobbit trilogies, Galadriel is played by Cate Blanchett. In The Lord of the Rings: The Fellowship of the Ring, Galadriel narrates the prologue that explains the creation of the One Ring, as well as appearing in Lothlórien.
Elros (portrayed by Robin Kerr) is an Elf of the Woodland Realm appearing in The Hobbit: The Desolation of Smaug. He is a captain of the Woodland Guard and Keeper of the Keys.
In The Fellowship of the Ring, Glorfindel was sent by Elrond of Rivendell in the direction that the Nazgûl were most likely to come from, to help the hobbit Frodo reach Rivendell. He set Frodo on his horse, Asfaloth, and has the hobbit riding ahead to the other side of the Ford of Bruinen, where he defies his pursuers.
Dark elves (svartálfar or dökkálfar) are “blacker than ink” and live in a subterranean realm called Svartalfheim. While – as we just mentioned – Snorri states that these dark elves are the dwarves, modern fantasy writers starting with Tolkien portray dark elves as a separate type of elf while keeping dwarves distinct.
Gimli is the son of Glóin who is introduced in The Hobbit as a member of Thorin Oakenshield's company, also being one of his four third cousins. Thorin himself is a direct descendant of Durin I, even becoming the King of Durin's Folk in his lifetime.
He had trust issues, especially when it came to the elves, which had stemmed from Thranduil abandoning the towards rather than helping them with Smaug attacked, and he had the gold sickness, but there were times he was willing to take a risk.
