King Caesar (キングシーサー, Kingu Shīsā), also spelled King Seesar or King Shisa, is an ancient statue guardian monster that fought alongside Godzilla in the 1974 film Godzilla vs. Mechagodzilla.
King Caesar is meant to be a shisa, a mythological beast resembling a cross between a lion and a dog. King Caesar stands upright on two legs and has brick-like skin, along with brown fur and two large floppy ears. In Godzilla vs. Mechagodzilla, King Caesar is 50 meters tall, 50 meters long, and weighs 30,000 tons. In Godzilla: Final Wars, King Caesar is 100 meters tall, 100 meters long, and weighs 50,000 tons.
King Caesar is actually a living statue built in the image of a shisa. Caesar guards over the royal Okinawan family of Azumi and rises to defend Okinawa and its people whenever they are threatened.
