Alex (Walking with Dinosaurs)

Alex is the best friend of the main protagonist Patchi. he's also the narrator of the movie.

In the movie
His exact nature is unknown, as in the bizarre universe of the film, he is shown to be a (totally unexplained) talking rook who can shape shift into an Alexornis, travel through time, and psychically communicate to people as well as dinosaurs.

In spite of being shown to have lived in Alaska for approximately 70 million years (his immortality is also unexplained) he has a Mexican accent, and he often feels a need to talk over ever potentially poetic or emotional scene, apparently with the intention of sucking the emotion out of it, or irritating the viewer.

He enjoys eating dinosaurs' tooth decay and insects.
