Story
Millions of years ago, when a meteorite crashed into the Earth, a few large dinosaurs managed to escape extinction burrowing underground. During their million years roaming underground, these dinosaurs evolved into the humanoid Abarokuns. Upon returning to the surface, the Abarokuns are infuriated when they discover that the planet they once roamed has been repopulated by humans. They soon start creating a formula--one that reconstructs a human being's DNA, turning him or her into a Abarokun with the mind of a dinosaur. Upon hearing about the Abarokuns & their kidnappings, a mad yet compassionate scientist recruits five incredible youth to fight back against the Abarokuns. He gives each of them a Chromostone, a DNA-shaped gemstone that contains the DNA of primitive creatures. These Chromostones allows our five young heroes to evolve into the superpowered Genshimen, & together they will fight the Abarokuns & save the future of mankind.
