[quote="thanigraphics"]yeah I didn´t really read the book either, just checking out some pics (there are way more new characters in it) but he seems to be evil in some way? Akril do you know what he did in the book?[/quote]
Okay...this is just from memory, I'm a bit too busy to look up the story at the moment:
One of the vultures of One-Eye's "pack" notices young Simba, Timon and Pumbaa (who is limping because of a hurt leg), and tells One-Eye about them. One-Eye decides to hunt them down with the help of his pack, and conceals himself in some tall grass while the jackals and hunting dogs herd the trio closer to him so he can pounce on them. Fortunately, Simba, Timon and Pumbaa manage to escape the pack, but the only place they can flee to is the eerie Monkey Mountain, a mountain shaped like a monkey's head, with a cavern forming a huge mouth. Strange, loud noises have often been heard coming from the cave, and many animals are afraid to go near it.
One-Eye and the pack chase them up the mountain, then Simba goes on ahead while Timon and Pumbaa stay behind to fight the pack off. Simba finds a monkey inside the cave, whose shrieks are greatly amplified by the shape of the cave. Simba then gets an idea. A little later, Timon, Pumbaa, One-Eye and the pack suddenly hear a tremendous roar coming from inside the cave. The pack scatters in terror and One-Eye leaps from the mountain and slinks away, alive but powerless. As it turns out, the roar was just Simba's roar amplified by the cave.
EDIT: Oh, and
here's the story where One-Eye appears.
