Dragotron transforms from a robot to a three-headed dragon with a tail that detaches to become a sword. Dragotron is similar to Beast Hunters Voyager Predaking but features slightly different coloration. The extra dragon heads are spring-loaded missile launchers that can also combine to form a larger weapon.
