Zyudenryu

Zyudenryu (獣電竜 Jūdenryū, lit "Electric Beast Dragons") are sentient dinosaurs given power by Torin to fight the Deboss Army during their first invasion. After defeating the Deboss Army for the first time, the Zyudenryu were frozen at the bottom of the sea until they were reawakened in response to the returned threat. When a Zyudenchi is used, the Kyouryu Spirit within the Zyudenchi causes the Zyudenryu to become a more powerful Battle Mode (バトルモード Batoru Mōdo), which allow them to be more suitable for combat and combine with other Zyudenryu.
