Regieleki is definitely the most feared of the Regis despite being the youngest, unlike its brethren following the paths imposed by Regigigas, guarding the realm from danger, Regieleki went down its own path, one of amusement through destruction and cruelty. Due to the threat of its growing power, it’s fellow Regis captured it and forced an ancient and indestructible magic harness on Regieleki, severely weakening its power. It was then locked in a tomb for eternity, the Regis then agreed that Regidrago would be held responsible of keeping Regieleki contained, only allowing Regieleki freedom every two thousand years when their king and creator, Regigigas, awakens from its slumber, it is the only being capable of controlling Regieleki as well as all the other Regis. Regieleki has an ongoing rivalry with Registeel, believing that it is the Regi holding the key to its harness. One can only hope that it never escapes whilst Regigigas is asleep for it will definitely hunt Registeel down in search of the key.
