Cretaceous King Ghidorah (白亜紀キングギドラ?, Haku Aki Kingu Gidora), is a three-headed dragon kaiju created by Toho that first appeared in the 1998 film Rebirth of Mothra 3.
Appearance Cretaceous King Ghidorah first arrived and attacked the Earth 130 million years ago in the Cretaceous period. Cretaceous King Ghidorah quickly caused the KT extinction event; he exterminated the dinosaurs and almost every other life form on the planet. Cretaceous King Ghidorah then encased himself within a meteor and left the Earth, using the life-essence of the creatures he had destroyed to live as he travelled through space. Millions of years later, during a meteor shower in 1999, the same meteor crashed into the Mount Fuji region, with Cretaceous King Ghidorah now being in his adult King Ghidorah form. Mothra Leo, as Rainbow Mothra, came in and attacked King Ghidorah, but ended up being overpowered by him. Then, with the aid of his priestess Moll, Leo transformed into Light Speed Mothra and traveled back in time to battle Cretaceous King Ghidorah, when he wasn't as powerful. During the battle, Leo cut off one of Cretaceous King Ghidorah's tails and the tail burrowed into the ground, which would regenerate an entire King Ghidorah body millions of years later. Cretaceous King Ghidorah was defeated when Rainbow Mothra used paralyzing powder on him and then dropped him into an active volcanic Mt. Fuji, destroying the first Cretaceous King Ghidorah.
