The streets will be safe with superhero Liv (Rose McIver) patrolling her city on the midseason finale of “iZombie.”

The episode — “Cape Town” — sees Liv eat the brain of a recently killed high school shop teacher who fancies himself a superhero vigilante that suits up in a cape and goes by the alias The Fog. To catch his killer, Liv’s going to have to put on a costume and secret identity all her own.

For Diane Ruggiero — “iZombie” co-creator and writer of this episode — turning everyone’s favorite zombie into a superhero is practically a dream come true.

“It’s my Christmas present to myself that there’s a fake superhero,” she tells Zap2it and a handful of other outlets on the set of the CW series. “Probably the funnest moment of my ‘iZombie’ experience thus far was coming up with fake superhero names.”

For Ruggiero, it all goes back to the 2011 HBO documentary “Superheroes,” about real-life people who take up the role of costumed vigilante in their own towns across the United States.

In fact, one of the most notorious real-life superheroes happens to be based out of Seattle — where “iZombie” is set. Phoenix Jones has been attempting to keep the streets of Seattle safe for years and was a member of the Rain City Superhero Movement — an organization of “costumed activists.”

Sadly, Phoenix won’t be seen on on “iZombie.” Luckily, there’s more than just The Fog and Liv’s alter ego to behold, though.

“iZombie” airs Tuesdays at 9 p.m. ET/PT on The CW.
