Fan Casting Werebat in Ben 10

The Lunaris, a species from Vulpin, inspired myths of werewolves and vampires. It has giant ears for navigation, retractable wings that can slash like a sword, and a disorienting bat-like growl. The Lunaris can also split its jaw in half in an intimidating display. Strengthened during full moons, it excels at night with sharp claws and tracking abilities. Its weaknesses include silver, sunlight, and anti-sonic devices. Werebat, a Vulpin, becomes one of Ben's many alien forms.
