Bagan was a Godzilla kaiju created for The Return of Godzilla, but was not used. He was also meant to show up in a number of other movies which were never made. He did appear in the SNES game Super Godzilla as the main villain and final boss. He was also meant to be in Godzilla Unleashed, but was cut in favor of Varan.
