On a distant planet humans, monsters, mages, and animals have coexisted for a long time, but the humans made a nation of machines and killed or imprisoned creatures that aren't ordinary animals and magical humans, whether they're good or evil. Monsters retaliated to establish dominance or to get revenge. Both sides think they're superior and war has gone on for 10 years with evil leaders on both sides. One boy and his friends fight their way to reason with the monsters' leader and end the war. They are Power Rangers Hero Force.
