If you didn't know, Koro is a Light Guardian. A Light Guardian are a dream who is like a demigod, meaning, once there old enough, they can become a king of a free or new type, or stay a light guardian. But if one is fulled with evil, they become a Dark Guardian and a Nightmare. All Light Guardians comes with a light gem, Light gems help them change there type, but is able to go back to normal. Right now, Koro is a Ice type Dream that takes the form of a Saber Tooth Cat cub, but, he would be a normal Saber Tooth Cat, but since hes 7, Hes mostly going to take the form of a young one.

Also Loko is the lil Dragon on his head. Hes kind of his butler/pet/bro/living health meter. So if Koro dies or the other way around, both would be dead.
