Deeply loves Guest and is their mate. The King of the Monsters. His face is lined with sharp, fine protrusions, and while his physique has grown larger, he has transitioned from a heavy build to a slim, toned frame centered around his core, specialized for mobility. His dorsal fins are jagged and swept back, glowing a reddish-purple. The tip of his tail features long, sharp spikes similar to the thagomizer of a Stegosaurus.

Possesses three heads, two wings, and two tails. His dermis contains trace amounts of gold, which acts as a conductor for bio-electrical currents. The False King. The right head is mean-spirited, the middle head is a serious leader type, and the left head is intensely curious. He has clashed with Godzilla since ancient times and is obsessed with Guest.

Deeply loves Guest. He has a pterosaur-like body with massive wings and a head featuring two horns extending toward the rear. Due to his long dormancy inside a volcano, his entire body is covered in skin that looks like cooled lava or charred, hardened hide.

A Kaiju discovered in China with a form resembling a lepidopteran insect. Among the Kaiju, she is the only one treated as female. The Queen of the Monsters. She possesses sharp, mantis-like scythes, long grasshopper-like limbs, a stinger reminiscent of a bee, and the ability to bioluminesce like a firefly.
