To fight monsters, you need a monster. But not just any monster — you need "Godzilla: King of the Monsters."

The final trailer for the sequel to 2014's monster mash is here and demonstrates the sheer destructive power of the humongous Kaiju that are threatening the world. Seventeen monsters — including Mothra, Rodan, and the three-headed King Ghidorah — cause untold chaos when they rise again to vie for supremacy.

Millie Bobby Brown,Vera Farmiga, Ken Watanabe, Kyle Chandler, and their fellow humans fight for survival, but they need some help — from one of those monsters ... Godzilla.

The trailer features some jaw-dropping action and effects in the battle scenes between the Kaiju (Ghidorah biting Godzilla — wow!). And it's all set to a haunting piano rendition of "Somewhere Over the Rainbow."

"Godzilla: King of the Monsters" opens in theaters May 31.
