Cockatrice

A cockatrice is a legendary creature about the size and shape of a dragon or wyvern, but in appearance resembling a giant rooster, with some lizard-like characteristics. It was supposed to be born from an egg laid by a cock (in the sense of a male chicken).

Its reputed magical abilities include turning people to stone by either looking at them, touching them, or sometimes breathing on them, like a dragon breathing fire. The cockatrice is very similar (if not identical) to another legendary creature, the basilisk. Its name may come from a folk etymology for crocodile.

The cockatrice is also a creature in the roguelike game, NetHack.
