King Caesar (キングシーサー, 'Kingu Shisa') is a bipedal kaiju from the Toho produced Godzilla. Caesar's appearance was inspired by the Shisa, a beast that looks like a combination between a lion and a dog. The shisa is prevalent in Okinawa mythology and is of Chinese origin. Its first appearance was in 1974's Godzilla vs. Mechagodzilla. He has made another appearance in 2004's Godzilla: Final Wars, as well as a Wii exclusive for Godzilla: Unleashed.
King Caesar appears with Mothra Leo, Anguirus, Rodan, Mothra and Baragon a few moments after Godzilla joins the Heroes, some of them do not trust the heroes at first, and have to be defeated by the monsters that trust the Heroes. Most noticeably, Godzilla. Caesar does not trust the heroes, so he has to be convinced.
