Plot
For generations, creatures known as Darkstalkers have been fighting to rule their home planet of Darkland, an Earth-like planet where monsters live. These creatures fight in a war called the "The Dark War". Each species sends one warrior to fight each other and the last one standing earns the title of "Darklord" and becomes ruler of Darkland, and its capital, Hades' Dystopia. The warriors are also given a necklace that, when activated, gives the warriors a fighting suit with special weapons to fight.

The Darkstalkers are sent to the city of Tokyo on the planet Earth, when the fight would take place. But as six of the Darkstalkers face off, they are suddenly attacked by an alien race known as Hellfire from the self-titled planet, who intend to invade every planet of the universe, and Earth is their current target. Worried that the invaders might target Darkland next, the six Darkstalkers put their differences aside and form the Horā sentai Darkstalkers to destroy the Firespark race and their leader, Flare. The six are later joined by four other Darkstalkers who want to protect Darkland.
