Death Tyranno, officially designated Drago Tyran or Shadow Tyranno, leads the Drago Clones. Diamond Ryugu, leader of the Dragozaurs, created these artificial replicas of the Dino Knights using the Dark Crystal's power. While matching the original Dino Knights in physical strength and combat prowess, the Drago Clones lack their cooperative instincts and strategic discipline.

Physically, Death Tyranno replicates Dino Tyranno's tyrannosaurus form and metallic warrior mode, distinguished by dark or shadow-themed coloration consistent with the Dragozaurs' aesthetic. His strength equals the original, capable of shattering the ground and creating fissures spanning multiple city blocks during combat. However, poor teamwork and impulsivity among the Drago Clones undermine his leadership.

In battle, Death Tyranno primarily targets Dino Ptera instead of his direct counterpart, Dino Tyranno. His operational history ends during a confrontation with the Cerazaur Brothers. While fighting Dino Ptera, her attack knocks him off a cliff. During his fall, he collides with fellow clone Drago Ceratops. This collision triggers a massive explosion that destroys two mountains, resulting in the deaths of both clones. With his final words, Drago Ceratops blames Death Tyranno for the incident.
