Kaiju No. 10 is an Identified Kaiju who attacked Tachikawa Base. It was created by Kaiju No. 9, and is considered a "prototype". It was then weaponized into Numbers Weapon 10, currently used by Third Division Vice-Captain Soshiro Hoshina.

In the manga, Kaiju No. 10 was a very tall and muscular humanoid kaiju, with a crimson-colored carapace, dull spikes on the back, and a long spiky tail. It had an elongated cranium with a sharp horn on the front and a cross-like cavity on the face, with multiple teeth around, connected to its upper jaw. Its mouth was large with two rows of teeth, sharp on the more external row and squared in the internal row. Inside its mouth, he had one circular blue eye placed, visible from the cross-like cavity on its face

Kaiju No. 10 is a ruthless and intimidating individual, driven to the utmost to accomplish its missions. He also seems to be quite confident, being a proud leader of a pack of kaiju and challenging the strongest member of the Defense Force he could find.
