Grant Shapeshifting

But afterwards the brothers fell out, and Neleus, being banished, came to Messene, and founded Pylus, and married Chloris, daughter of Amphion, by whom he had a daughter, Pero, and sons, to wit, Taurus, Asterius, Pylaon, Deimachus, Eurybius, Epilaus, Phrasius, Eurymenes, Evagoras, Alastor, Nestor and Periclymenus, whom Poseidon granted the power of changing his shape. And when Hercules was ravaging Pylus, in the fight Periclymenus turned himself into a lion, a snake, and a bee, but was slain by Hercules with the other sons of Neleus. Nestor alone was saved, because he was brought up among the Gerenians. He married Anaxibia, daughter of Cratieus, and begat daughters, Pisidice and Polycaste, and sons, Perseus, Stratichus, Aretus, Echephron, Pisistratus, Antilochus, and Thrasymedes.
