Known as "The Monster of the Beginning," Deathdrago is a Destructive Rampage Dragon that once appeared before mankind.

It fires powerful electric shocks from the two large horns on its head, one of which is broken in half.
After its battle with Ultraman Trigger, Deathdrago escaped deep underground, where it was manipulated by Carmeara into becoming the Destructive Dark Rampage Dragon, gaining red-tinted eyes and supercharged red electric blasts.
