History
Heisei Series
Rebirth of Mothra III
In 1999, a meteor shower was raining over the night skies over Japan with one meteorite crash down in the Aokigahara region of Mount Fuji. Moll and Lora examined the remains of the crashed meteor, realizing that King Ghidorah had escaped, and sensing a great evil had been released. King Ghidorah emerged from the meteor to attack Tokyo and began 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. Rainbow Mothra arrived and battled King Ghidorah, but Leo's beams were repelled by space monster's force barrier. King Ghidorah easily defeated Rainbow Mothra. After Leo was healed from his battle and transformed into Light Speed Mothra, Moll sent him back in time to attack Cretaceous Ghidorah when he first arrived on Earth and was not so powerful.
When Leo killed Cretaceous King Ghidorah, King Ghidorah and the dome disappeared, freeing the trapped children and the fairies. However, King Ghidorah reappeared in the sky amidst a massive fireball and resumed his reign of terror. Leo was reborn from his cocoon as Armor Mothra and engaged King Ghidorah in battle again. Armor Mothra sliced off King Ghidorah's left wing with his own razor-sharp wing then completely destroyed him with his Excel Dash Buster.

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.
