POLYBOTES:¹⁾https://en.wikipedia.org/wiki/Giants_(Greek_mythology). According to Apollodorus, he was crushed under Nisyros, a piece of the island of Kos broken off and thrown by Poseidon.²⁾Apollodorus, 1.6.2. He is named on two sixth century BC pots, on one (Getty 81.AE.211) he is opposed by Zeus, on the other (Louvre E732) he is opposed by Poseidon carrying Nisyros on his shoulder.³⁾Getty 81.AE.211 (Moore 1985, pp. 30–31, Beazley Archive 10047, LIMC Gigantes 171); Louvre E732 (Gantz, p. 451, Beazley Archive 14590, LIMC Gigantes 170 image 4/4).

Polybotes⁴⁾http://greekmythology.wikia.com/wiki/Polybotes (Πολυβωτης) – Poseidon – Poseidon buried Polybotes by throwing part of the island of Kos, thus creating a new island Nisyrus. Polybotes was one of the Gigantes, son of Gaia and Tartarus, born to oppose Poseidon. He was one of the three Gigantes Kings

In the Gigantomakhia, Poseidon chased Polybotes across the seas, then, when they fought, Poseidon tore of part of an island and threw it at Polybotes, thus not killing him, because a Gigante can only be killed with a god and a human together, but trapping him under the island.

Parents: Gaia and Tartarus

Ancient Text: “They say that Nisyros is a fragment of Kos and they add the myth that Poseidon, when he was pursuing one of the Gigantes, Polybotes, broke off a fragment of Kos with his trident and hurled it upon him, and the missile became an island, Nisyros, with the Gigante lying beneath it. But some say that he lies beneath Kos.”
-Strabo, Geography 10. 5. 16 (trans. Jones) (Greek geographer C1st B.C. to C1st A.D.)

Polybotes⁵⁾http://www.greekmythology.com/Myths/Gigantes/Polybotes/polybotes.html was one of the Gigantes in Greek mythology, the children of the Titans Uranus and Gaea. The Gigantes emerged from the earth (Gaea) when Uranus was castrated by his son Cronus and his blood fell onto the soil. During the Gigantomachy, the great battle that happened between the Olympian gods and the Gigantes, he fought against Poseidon, and he was eventually crushed under Nisyros, a part of the island of Kos that Poseidon broke off and threw against him.
