Matango Island

Matango Island is the name of a small island in the South Pacific, a few hundred miles off the coast of Japan. It first appeared in the 1963 film Matango.

Some time before the events of the film, a ship came ashore on the island. Its crew disappeared, leaving the ship to get covered in mould. Later, another ship full of several young men and women ran aground on Matango Island in the midst of a storm, disabling their boat. Exploring the island, they found what looked like a paradise - a lush jungle adorned Matango Island, full of pools containing clean water and an abundance of strange looking mushrooms. At first, the survivors refrained from consuming the fungi, afraid of what it would do to them. Eventually, one survivor grew desperate, and ate one of the mushrooms. What followed was to bring terror to the peaceful island. Gradually, the man began to mutate and grow fungus all over their body, eventually transforming completely into the hulking Matango! Over time, more and more of the survivors became infected, until one survivor managed to escape on the mouldy boat. However, upon his return to Japan, he too begun to slowly be colonised, ending his sanity by remarking on how similar humans and Matango were to each other.

Matango Island is once again home to the Matango Mushrooms, and a curiously different version of Hedorah, called Neo Hedorah. Neo Hedorah leaves the island and travels to fight the other monsters.
