In 1999, a meteor shower was raining over the night skies over Japan with one meteorite crash down in the Aokigahara region of Mt. Fuji. Moll and Lora examine the remains of the crashed meteor, realizing that King Ghidorah has escaped, and sensing a great evil has been released. King Ghidorah emerge from the meteor to attack Japan and begins to feed on humans, mainly children, but he soon started to eat adults. King Ghidorah built a dome in the Mount Fuji area where he kept his victims and absorbed their life forces. King Ghidorah scoured Japan, transporting his prey, inside of a pulsating feeding dome hidden within Fuji forest. Not long when Rainbow Mothra was called by the Elies arrived to stop Grand King Ghidorah arrived to stop King Ghidorah's depredations, but Leo's beams are repelled by space monster's force barrier. King Ghidorah quickly defeated Mothra Leo to the ground. After Leo was healed from his battle and transformed into Light Speed Mothra, Moll send Mothra Leo traveled back in time to attack Cretaceous Ghidorah when he first arrived on Earth and was not so powerful.
When Leo seemingly killed Cretaceous Ghidorah, Grand King Ghidorah had vanished and it appeared to be victorious. However, King Ghidorah reappeared in the sky and resumed his reign of terror, having regenerated from the tail that Leo severed it millions of years ago. Leo was reborn from his cocoon as Armor Mothra and engaged King Ghidorah in battle again, this time proving to be the more powerful combatant. Armor Mothra sliced off King Ghidorah's left wing with his own razor-sharp wing then completely destroyed him with Excel Dash Buster.
A suicidal man attempted to hang himself from a tree in the Aokigahara. The man tied his tie to a tree branch and stood atop a fallen shrine, only for the ground beneath him to collapse and cause him to fall into a cavern. In the cavern, the man saw King Ghidorah, a three-headed dragon that was frozen in ice. Later, the prophet Hirotoshi Isayama traveled to the cavern and awakened Ghidorah so he could help Mothra defeat Godzilla.
