Legolas

Early life
Legolas was born to Thranduil, and his wife, the unnamed Queen of Mirkwood. He grew up with Tauriel, whom he fell in love with as they grew older. When he was young, Legolas' mother was killed during a battle in Gundabad during another age. He grew up without a mother, no grave for him and his father to mourn at.

Legolas grew up to be arrogant and cold-hearted against dwarves.

Throughout The Lord of the Rings Trilogy
Making up with his Father, Legolas goes to attend the meeting of Lord Elrond about the One Ring found after centuries of its absence and reuniting with Aragorn, while striking up a rivalry with one of the dwarves, Gimli, who dispises Legolas because his father, the King, imprisoned his own. During the Council, when one of the council members, Boromir, ridicules Aragorn for knowing such things about the One Ring, Legolas defends his old friend and states that Aragorn is no mere ranger, but is Aragorn son of Arathorn and that Boromir, as a man of Gondor, must owe his allegiance to him. However, Aragorn, in Elvish, tells Legolas to sit back down. Boromir declares Gondor does not have a king and does not need one. and continues to ridicule the situation at hand, especially declaring that they cannot enter Mordor due to its high security and its climate. Legolas shouts in rebuttal that the Ring must be destroyed, just as Lord Elrond said. However, this causes a spark of rebellion among the members, and they begin arguing, except for Frodo who declares that he will be the one to take the ring to Mordor, but says he does not know the way there. Legolas promises his bow and his services to Frodo, as do Boromir, Gandalf, and Aragorn. Gimli joins in as well, much to Legolas' chagrin, but the two will have to learn to cooperate. Three more hobbits Samwise Gamgee, Peregrin Took, and Meriadoc Brandybuck later join as well, thus marking the beginning of the Fellowship of the Ring.
