This papercraft is Legolas Greenleaf, an elf who was part of the Fellowship in the Third Age, based on the film “the Lord of the Rings“. The paper model was created by J. Ossorio. He is the son of the King Thranduil of Mirkwood, was a Prince of the Woodland Realm, a messenger, and a master Bowman. With his keen eyesight, sensitive hearing, and excellent bowmanship, Legolas was a valuable resource to the other eight of the Fellowship. His age was never stated by Tolkien but was estimated by some to be between 500 and 3000 years old, which is not uncommon for Elves. Legolas became great friends with the dwarf Gimli, who was also a member of the Fellowship of the Ring.
It is not known whether Legolas was Thranduil's only son, or whether he was heir to his father's crown.
Although he lived among them and in their culture, Legolas was not fully of the Silvan Elves. As a son of the Elven-king Thranduil, who had originally come from Doriath, Legolas was at least part Sindarin Elf, as his mother's identity is completely unknown. This is complicated by the fact that a small minority of Sindarin Elves ruled the predominantly Silvan Woodland Realm of Northern Mirkwood, a minority to which Legolas belonged. The Sindarin minority in that realm, who should have been nobler and wiser than the Silvan Elves, can be seen as having "gone native" at the end of the First Age: after Morgoth was defeated and all of the grand Elf-kingdoms of Beleriand were destroyed, they can be seen as going back to "a simpler time" in their culture.
Like all elves, Legolas has a great respect and appreciation for nature. While in Fangorn Forest he longed to return once more in order to explore its wonders more thoroughly. He is kind, and cares greatly for his friends, even Gimli the Dwarf, though it was a rarity for Elves and Dwarves to express a liking for one another. Due to his age however, he sometimes seems rather patronizing toward the mortals around him.
