Synopsis by Mark Deming
Two great heroes join forces in this sci-fi adventure tale from Japan. Two deadly emissaries from the planet Monera have arrived on Earth with global destruction on their minds -- the giant robot Deathfacer and a huge and terrifying monster known as Queen Monera. As the international monster-defense league Super G.U.T.S. (Global Unlimited Task Squad) tries to plot a proper response to this two-pronged attack, two of the world's greatest superheroes join forces to help them meet the menace -- Ultraman Tiga and Ultraman Dyna. Ultraman Tiga and Ultraman Dyna was the first feature film to bring together the characters from both of these popular television shows from the Ultraman franchise.
