Dokyura

Dokyura appeared in 1985 TV series called Dengeki Sentai Changeman. Dokyura is a Space Beast of the Great Star League Gozma. A bat-like Space Beast from the planet of vampires. Has the ability to fly and fight with sharp teeth and claws. His special technique is to "bite" people using a tube that emerges from his mouth; the bite infects anyone hit by it that he chooses with a virus that turns them into a pale-skinned bloodsucker similar to the legends of vampires. The people infected can turn back to normal, but will become vampires again when Dokyura emits an ultrasonic wave that awakens the effect of the virus. Although initially protecting himself with an army of young females he created on Earth prior to meeting with the Gozma, the Changeman are able to seize most of the infected girls and place them in a room where his ultrasonic shriek would not reach them; while Oozora uses a girl he befriended infected by the alien bloodsucker to draw him out and defeat him in an aerial battle before destroying him with the Power Bazooka, then Change Robo. Dokyura loves blood so much so he actually ditch his first meeting with the general to go sample some of earths blood. Then when Navigator Gator complained about it he drank his blood. He's very picky about what kind of blood he likes telling Gato his blood his terrible. he was also a coward who used his victims has human shields ran away even when he had the advantage and his the only giant monster to ever try and run from Change Robo.

His plan is to "bite" people using a tube that emerges from his mouth; to spread the vampire virus on earth. each bite infects anyone  bitten by him hit by him into a pale-skinned bloodsucker similar to the legends of vampires. and like the vampire of legend they could also turn others they bite into vampires. In Gozmas own worlds he'd turn them into beast that hate each other and tear there own planet apart. The people in question could be turned back and forth between humans and vampire form by a special ultrasonic wave created by Dokyura that awakens the effect of the virus. Those allowing the people in question to act has sleeper agents going about there normal live until summoned to expand the horde. All victims turned are shown to be young woman but its unclear if only they can be turned or if this just Dokyura's preference.Dokyura him self used the girls has human shields against the Changemen. When figthing on his own he had the ability to fly and fight with sharp teeth and claws.
