My Monsterverse Part 5. Godzilla: King Of The Monsters

G's rule provides years of relative calm from Titan disruption, but a meteor crashes to the Earth and King Ghidorah rises to challenge Godzilla's supremacy.

Godzilla and Rodan team up against the alien invader. They struggle greatly against the three-headed dragon until Mothra emerges from her chrysalis as a fully formed giant butterfly. She joins the fight and tilts the balance in their favor.

Ghidora escapes, but not without the loss of one of his heads, torn from his body by Godzilla's jaws. 

The epilogue reveals that this attack is merely the prelude to a greater invasion.
