Twilight Ranger

POWER RANGERS VAMPIRE SYMPHONY (Ongaku Sentai Vampiranger)
Full Burst Mode is the hottest rock band in the world right now, already sporting double platinum with their forth album and topping the charts they are now on tour throughout America.....unfortunately they happen upon a far off corner of America notorious for sightings of vampires. And well, after their lead singer Marceline is kidnapped by this asshole calling himself "Prince Alucard", a whole incident ensues involving all three members aided by a centuries old vampire hunter named Jonathan in slaying the vampire prince. But as he was dying he decides to try an infuse his dark soul into the three musicians to survive, Jonathan then calls upon the remnants of Zordon to come beyond the grave and save them from this dark infusion....in the end it turns them into a strange new breed of half vampires, the Vampirangers.

And things get worse from there as the Vampire Princess Marishka (who bears an uncanny resemblance to Azula from Avatar) swears revenge for the death of her husband hunting the Vampirangers down along with her two lieutenants Aleera and Verona (who bear an uncanny resemblance to Ty Lee and Mai). Adding the Vampire Princess in her hunt is a legion of Vladshades, creatures of horror (and other such classic literature and legends) with powers and forms beyond logic and reason, even beyond madness itself!

And so the members of Full Burst Mode have to endure a new reality as the Vampirangers, dark power wielding defenders of the world not only fighting against the creatures of the night but also trying to finish their national tour without any more hiccups.

"Zarks Baohterra"
The only surviving member of the lost Twilight Rangers, formerly the Red Twilight Ranger his designated color has long since faded. He has lived for a thousand years or so under the name "Jonathan", his immortality put upon him by his former ally and friend Prince Alucard, the former sixth Twilight Ranger. Whatever remained of Alucard's Ranger powers and humanity now lives on in the newly formed Vampirangers, as such Zarks himself now stays with the new Rangers as their trainer and mentor.

True to the name "Twilight" his Ranger power utilizes both light and dark magic in unison, he has no other weapons or tools other than the three relics that can combine into a powerful crossbow weapon. With the death of Prince Alucard the curse that made Zarks immortal was lifted, because of his extreme old age he could easily expire at any moment. The only thing keeping him alive is in fact his Twilight Ranger power which is now severely finite, each time he transforms and uses his power he is that much closer to the end of his life.
