Godzilla is about to have some competition. In a new video, Legendary Entertainment teased the MonsterVerse origins of Godzilla's opponents Rodan and King Ghidorah in anticipation of 2019's Godzilla: King of the Monsters.The video shows a timeline of Monarch's activities as they monitored and documented the existence of gigantic creatures on Earth since the events of Kong: Skull Island, which was set in 1973. The clip starts with Monarch quarantining a volcano on Isla De Mona in 1991, which hints at Roda, an irradiated Pteranodon that nests on volcanoes as seen in his debut feature Rodan (1956).RELATED: Godzilla: King of the Monsters Director Teases Film’s Beastly RosterThe video then cuts to a direct reference to the three-headed, dragon-like kaiju known as Ghidorah, which was found "sealed beneath the Antarctic ice shield" in 2016, two years after the events of Godzilla in San Francisco. The marker, labeled as "Monster Zero," also contains a footnote from Monarch's Dr. Vivienne Graham (Sally Hawkins) that says "the devil has three heads," which makes it clear that this monster is indeed Ghidorah.

According to the studios’ press release, Godzilla: King of the Monsters will follow “the heroic efforts of the crypto-zoological agency Monarch as its members face off against a battery of god-sized monsters, including the mighty Godzilla, who collides with Mothra, Rodan, and his ultimate nemesis, the three-headed King Ghidorah. When these ancient super-species — thought to be mere myths — rise again, they all vie for supremacy, leaving humanity’s very existence hanging in the balance.”

Releasing in theaters on March 22, 2019, Godzilla: King of the Monsters is a production of Legendary Entertainment directed by Michael Dougherty and starring Vera Farmiga, Ken Watanabe, Sally Hawkins, Kyle Chandler, Millie Bobby Brown, Bradley Whitford, Thomas Middleditch, Charles Dance, O’Shea Jackson Jr., Aisha Hinds and Zhang Ziyi.
