Chorakhe

Chorakhe is the titular antagonist in the movie of the same name

A mutant crocodile who was created by atomic testing in the Pacific Ocean, the crocodile wreaks havoc on a Thai village and devoures any living being he comes across. He later battles two doctors and a fisherman who have been sent to destroy the voracious animal. The crocodile is finally defeated when one of the men causes the ship to explode as he is later rescued, however, it is possible the crocodile survived the event and reformed. The 1985 film Magic Lizard features a similar crocodile that first appears as a statue which is accidentally released by the film's titular character. Due to the similar sfx, the crocodile could most likely be the same one from the previous film.
