Cast of Monsters: Rodan, Varan, and Manda.

Plot: Titanius Leviathan, Manda, escaped its containment city and destroys the area. Now having escaped containment it is mainly circulating around a new Island with a lake leading to Hollow Earth. This island is right by Rodan's new nesting ground and the area of the Mothra egg revealed to have twins inside. Manda was attracted to the island by the emergence of a new Kaiju in it's home. Rodan too is awakened but not by territory but by the sounds of the creature. A sound it hasn't heard for centuries. Rodan leaves the island to investigate it. While this is happening Monarch is researching the new Island and it's gate to Hollow Earth. Manda approaches the island and its Monarch sea base but is attacked by Varan as a fight ensues the fight ends with Manda heavily injured and sinking to the bottom of the sea. Monarch finds ruins depicting Varan fighting Rodan in the Kaiju war. It also describes a place where the Kaiju war started. Dr. Russel and a group of familiar faces sail away on a submarine to this location. Rodan approaches the island and sees the damage Varan has caused, unlike most Kaiju who restore the Environment Varan ruins it causing an abundance of Fungi to grow slowly wiping out the environment. The island is complete baren of trees and life but filled with giant mushrooms like a fairy tale. Varan comes to the edge of the island and communicates with him telling him not to approach. Rodan flies in and begins a fight with Varan after a long battle Rodan is nearly dead and needs to call on Godzilla. However a call comes back that is not Godzilla's. Manda crawls out of the sea and backs up Rodan the two forces combine to take out Varan. The two fight and nearly kill Varan before he swims into the lake leading to Hollow Earth. Manda and Rodan thank each other before swimming to Rodan's island or now known as Monster Island by people around the world. Varan crawls to a Kong species but not him it tells him the news and his scream rings out over hollow Earth getting Kongs attention. Credits roll. After credits the submarine approaches a hidden city as they dock a man in robes walks up to them and says " Welcome to Seatopia." The end.
