There once was a species of Raposa called a Rapotaur. The toughest types of Raposa whir the Rapotaurs. At one point in time one of them attacked the town of Lavasteam and from then on it was a war between Raposas and their centaur like counterpart, when the war was over there was one Rapotaur left this one was hard to get because it had armor on its body and plus this one had special powers that whir sealed in with a blue oval shaped gem it bared around its neck. So in order for the Raposas to defeat the armored Rapotaur they needed to call a upon the creator to make a hero to defeat the Rapotaur and then the hero pierces the blue gem it fell crashing to the ground and to mark the battle the towns Raposas made a big hole and placed that last remaining Rapotaur in it and then made a temple on top of it.
Until 90 years later a human like Raposa named Gizmo snuck into the temple and got the blue colored pendent and then putted it around his neck he felt this massive power flowing through him then snuck out in his new form but what he didn't note the strange righting on the temple wall which redid: Who ever obtains this pendent obtains the power of the Rapotaur. But luckily for Gizmo he was a regular Raposa to start out with so with that pendent he can switch in between forms and plus for some reason
The evilness of the form isn't there so he suspects someone was there before him and directly obtained the evil part for them self.
