The elemental rings are a collection of magical rings containing unknown power. The crusaders are tasked with finding and retrieving said items in order to complete a riddle. All of the recovered rings are safely stored on Captian Apollos hand. Upon completing the set he has asked MotorKnight to cut off his hand to prevent him from being possessed.
So far the rings have been shown to contain some sort of demonic presence, as evident from the voices Apollo hears in his thoughts.
Flamora- An angry, hot-headed woman who wishes to bring wrath upon her enemies. During battle she whispers to Apollo to release his full power and use her. She is the ring of fire.
Venta- Venta is calm and collected, she is incredibly tactical in combat, she whispers to Apollo to think each battle well and for each cut to be calculated and deadly. She is the ring of air.
