Kong: Skull Island
Hank Marlow acted as a Lieutenant during the events of World War II, before being stranded on Skull Island. He crashed on the island with a Japanese pilot named Gunpei Ikari, who still continued to fight until Ikari almost killed Hank, but then a gigantic gorilla known as Kong showed up and scared off Ikari. Hank spend the next course of 30 years stranded on Skull Island, during the time he began living with the people on, the Iwis, who would tell him about how Kong as considered to a god to them and the last of his kind, who were slaughtered by a race of subterranean reptile creatures, that he would dub "Skullcrawlers" and the only thing keeping from destroying all life on the island, and he even became friend with Ikari, until he was killed by one of the Skullcrawlers. He then encountered James Conrad and his band of travelers during their expedition to the lost island, explaining who Kong is, while also speaking about the "devils" who lived below, also known as the Skullcrawlers.
