Ultraman Tiga & Ultraman Dyna & Ultraman Gaia: Battle in HyperspaceKing of Mons was a kaiju created by the evil thoughts of Hiroshi Kashimada, an ultra kaiju fanatic who wanted to make the strongest monster to defeat Ultraman Gaia. Using the Red Sphere that brought Gaia into the their world, and making his kaiju out of a clay statue as a demonstration of what he would look like, Hiroshi's creation came to life as his wish to the red sphere, and King of Mons was born. In accordance to his master's wishes, King of Mons immediately began to destroy everything that was in his sights: The City. With no proper opposition in the real world, nothing could stop King of Mons's rampage. Eventually, Gamu returned to Tsutomu's world, piloting the XIG vehicle, The Adventure and battled with King of Mons himself. Although the Adventure put up a good fight, King of Mons was more superior in battle and The Adventure was destroyed.
Shortly after, Gamu transformed into Ultraman Gaia and battled with King of Mons himself. Just as it appeared that Gaia was winning, King of Mons spewed forth Bajiris and Scylla, monsters created by Hiroshi's co-horts while creating King of Mons. Together all 3 kaiju triple-teamed Gaia and the battle was one-sided once again. Not giving up hope, Tsutomu found the Red Sphere and made one more wish to help Gaia. Granting Tsutomu's wish, Ultraman Tiga and Ultraman Dyna were manifested and came to assist Gaia against the 3 kaiju. As Tiga fought with Scylla and Dyna fought with Bajiris, Gaia was once again left alone with King of Mons and soon regained control of the fight. After Scylla and Bajiris were killed by Tiga and Dyna, King of Mons was crippled as a result of their deaths, leaving him to be destroyed by Gaia's Photon Stream.
