The opening trailer is narrated by Dr. Andrews (Rebecca Hall), affirming that ‘Human civilization always believed that life only exists on Earth.” The image of Hollow Earth appears, full of richness and mystery. Kong returns home and discovers a marvelous world alongside exotic creatures. Meeting a fellow ‘little titan’, Kong broadens his understanding of his family.

Dr. Andrews’ exploration team discovers giant red footprints, reminiscent of a colossal Godzilla. Enter Skar King – a new titan with fierce red fur and unimaginable killing abilities. Skar King seems to be Kong’s direct adversary, forcing them and Godzilla, former enemies, to unite to confront.
