Vampirella

Creation
Vampirella is a fictional character created by writer Forrest J Ackerman and artist Trina Robbins. Her first appearance was in Vampirella #1 published by Warren Publishing in September of 1969.

Origin (Warren Comics)
In her first appearance in Vampirella Volume 1 Issue 1 (September 1969) Vampirella, or Vampi as she likes to be called, was a vampire from the planet Draculon. On Draculon blood abundantly flowed the same way water does on Earth. However, over time Draculon's twin suns began to emit so much intense heat that the oceans of blood on the planet started to dry up. As fate would have it, a space shuttle from Earth crash landed on Draculon. When Vampi went to investigate the strange craft in her "bat form" the Earthlings who piloted the ship attacked her out of fear. When Vampi fought back in self defense she discovered these other worldly visitors possessed blood in their veins. The same life giving blood that once flowed on Draculon. Upon learning this Vamirella made her way to Earth.

Powers & Abilities (Warren Comics)
Shapeshifting Vampirella possesses the ability to transform into bat.

Flight Vampirella was once able to fly via small bat-like wings on her back, which she could materialize at will. However, in Vampirella Volume 1 Issue 8 (November 1970) Vampi lost the use of her wings after they were amputated by cult leader Ethan Shroud.

Origin (Harris Comics)
In the fictional universe of Harris Comics vampires did not come from another planet, but rather are descendants of Lilith, the first wife of Adam. Lilith was cast out of the Garden of Eden by God when she refused to submit to Adam. After her banishment from the Eden Lilith mated with several demons, which lead to her giving birth to the first vampires. It is later revealed that Lilith's life force is bound directly to her vampire children. Thus, whenever a new vampire is created Lilith's power is diminished. Lilith creates Vampirella by mixing her own blood with the soil of Draculon, which in the Harris Comics universe is a portion of Hell given to Lilith by the Devil himself. Lilith then brainwashes Vampirella into believing that all her vampire brothers and sisters are evil and must destroyed.

Powers & Abilities (Harris Comics)

Flight Vampirella is able to fly via small bat-like wings on her back, which she can materialize at will.
