Daikaiju (Japanese for 'Great' or 'Giant' Monster) is a general term used interchangeably to describe giant monsters, or Kaiju. In the Ultra Franchise, the term generally refers to monsters that are much larger than the Ultras they fight. The shortest Daikaiju is Gatanozoa, whose height is roughly one and a half times greater than Ultraman Tiga's height. The longest one is held by Zoruim, which length was never proven due to his full size never being shown on screen, followed by King Myra, whose height will continue to increase unless he is killed. The largest Daikaiju is Vacuumon, as it's size is infinite.
