Have you seen James Cameron's Avatar?

Do you know the ritual that the Na'vi have to tame the Ikram? Its basically the same thing.

Duvari are herbivores and are used as mounts. Its expected that the "tamed" duvari have completely lost their natural instincts. But the ones that the Nasri breed, are practically wild ones. They will attack you if they feel threatened.

PS: the Duvari are inspired by Thanators, from the same movie.
