Last month, Apple TV released a teaser for the second season of Monarch: Legacy of Monsters, part of Legendary Entertainment’s MonsterVerse, which brought Godzilla, King Kong, and various other monsters (kaiju) created by Toho Co., Ltd into a shared narrative. But we only got the most fleeting glimpse of the promised new mythical Titan threatening the human race. The full trailer just dropped and rectifies that: it’s a gigantic tentacled undersea being dubbed Titan X—and only Kong and Godzilla can stop it.

(Spoilers for Season 1 below.)

As previously reported, the first season picked up where 2014’s Godzilla left off, specifically the introduction of Project Monarch, a secret organization established in the 1950s to study Godzilla and other kaiju—after attempts to kill Godzilla with nuclear weapons failed. In the S1 finale, Godzilla fights off an Ion Dragon, tossing it through a rift back to the Hollow Earth, and Lee Shaw (Kurt Russell) seemingly sacrifices himself to save his colleagues. Per the official Season 2 premise:

Season two will pick up with the fate of Monarch—and the world—hanging in the balance. The dramatic saga reveals buried secrets that reunite our heroes (and villains) on Kong’s Skull Island, and a new, mysterious village where a mythical Titan rises from the sea. The ripple effects of the past make waves in the present day, blurring the bonds between family, friend and foe—all with the threat of a titan event on the horizon.

In addition to Russell, returning cast members include Wyatt Russell (son of Kurt) as the younger Shaw; Anna Sawai as Cate Randa; Kiersey Clemons as May; Ren Watabe as Kentaro Randa; Joe Tippett as Tim; Elisa Lasowski as Duvall; and Anders Holm playing the younger version of Monarch researcher Bill Randa. Takehiro Hira, Amber Midthunder, Curtiss Cook, Cliff Curtis, Dominique Tipper, and Camilo Jiménez Varón will join the S2 cast as guest stars.
