Treebeard

Treebeard (Sindarin: Fangorn) is a fictional character from J. R. R. Tolkien's Middle-earth fantasy writings. The eldest of the species of Ents, he is said to live in the ancient Forest of Fangorn and stands fourteen feet in height and is tree-like in appearance, with leafy hair and a rigid structure. Fangorn Forest lies next to Isengard where Saruman the White resides. His motto is "Do not be hasty."

In The Two Towers he meets with Meriadoc Brandybuck and Peregrin Took, two Hobbits of the Shire known also as Merry and Pippin. Treebeard is known to have a strong hatred of Orcs, and, after Saruman's betrayal of the Ents, of Saruman as well.
