How Old & Powerful Is Treebeard In Lord Of The Rings?

Treebeard is among the more mysterious characters in The Lord of the Rings, with much of his history and power only implied rather than overtly stated. The tree-like being, who was also named Fangorn, told the Hobbits, Merry and Pippin, a fraction of his story, and Gandalf later provided a bit more about the old tree as he talked with Aragorn, Gimli, and Legolas in The Lord of the Rings: The Two Towers. This allows us to understand who this oldest of Middle-earth beings was, where he came from, and how long he tended to the trees in Fanghorn Forest.
