Kishiryu
The Kishiryu are sentient dinosaurs that were created by the Ryusoul Tribe as a countermeasure to the Druidon before being sealed within temples throughout the world. They can combine with each other via Ryusoul Combination. Amidst the Ryusoulgers' final battle with Eras, the Kishiryu sacrifice themselves to empower the Ryusoul Calibur.
