Prior to the extinction of the dinosaurs, 24 specific prehistoric animals were given the power to become Zyudenryu so they could fight back against the alien invaders. The majority of the Guardians (the lesser Zyudenryu) were decimated, but their spirits were preserved in batteries powered by the energy source known as Brave. These batteries hold the Kyoryu Spirits of the animals they represent and essentially grant the Kyoryugers their arsenal. The batteries of the Zyudenryu meanwhile allow those chosen to become Kyoryugers.
Doctor Ulshade is the partner of the Zyudenryu Plezuon.
