Liv won’t be a typical zombie like those in The Walking Dead. Check out the zombie heroine in action in the first iZombie trailer.

Combining Veronica Mars creator Rob Thomas’ talents with a comic book series takes the leading lady of this show to the next level of badass.

Not only will Liv be full of all of the spunk and sass of her Marshmallow companion, she’ll also be impervious to pain. Watching the first iZombie trailer’s action-packed sequences, we can’t help but wonder the biology of the thing.

Is a bite or scratch enough to turn someone into a zombie? Would the victim have to die at the hands of the attacking zombie, or would an infection on a living person eventually take root?

Watch the first iZombie trailer below:

iZombie‘s release date was announced earlier today, along with many stills from the pilot episode of the show.

iZombie follows Olivia “Liv” Moore (Rose McIver, Masters of Sex, Once Upon a Time) as a peppy medical resident-turned zombie after she attends a party that ends up being a zombie feeding frenzy. Liv takes a job up at a coroner’s office to satiate her hunger of brains via John and Jane Does, but soon realizes that she retains some memories of the owners of the brains.

With the help of coroner Dr. Ravi Chakrabarti (newcomer Rahul Kohli) and homicide detective Clive Babineaux (Malcolm Goodwin, Breakout Kings), Liv poses as a psychic to find out not only the identities of the Does, but also the location of the original zombie responsible for Liv’s condition, Blaine Debeers (David Anders, Once Upon a Time, The Vampire Diaries).

How do you think the zombie science in ‘iZombie’ will play out?
