Mothra is a flying type of Kaiju which is like a butterfly but is also good. Ghidorah is a flying dragon with 3 heads. It is also a bad Kaiju. He tries to kill different Kaiju because he wants to become the king of monsters. Roden is like a taradactle bird which lives in a volcano and has fire with him which is bad because he is also big.
