Our protagonist, a cheerleader from San Romero High School who doubles as a professional zombie hunter. In the process, she embodies everything fun about The Ditz and The Tease. Juliet wakes up on her 18th birthday to find her school overrun with zombies. With her chainsaw, the support of her zombie-hunting family, and the still-living severed head of her boyfriend Nick, she sets out to stop the zombie apocalypse from totally ruining her birthday.
Genius Ditz: She's knowledgeable in all things zombie-related and is an accomplished necromancer, and is highly adaptable to extreme environmentsnote She also has a 3.4 GPA, which is higher than might be expected but not that impressive on a national scale. She's also, well, a ditz.
Girls Love Stuffed Animals: She has a favorite stuffed toy rabbit, which she is seen cuddling in the intro. One of her extra costumes is modeled after the same rabbit.
Goofy Print Underwear: She tells Nick that she is wearing her special zombie-hunting underwear, which, according to her training, is cotton panties with teddy bears or hearts on them.
Hidden Depths: She may think it's totally cool that she has a severed head for a boyfriend, but if her Dream Sequence at the start of Stage 3 is to be believed, she fears that he'd rather become a zombie than continue living as just a head.
Stripperific: Her normal and alternate cheerleader outfits are pretty skimpy. Then there is the time you can have Juliet tear through the walking undead wearing naught but a bikini, one of them a seashell bikini.
Sweet Tooth: For lollipops, which also restore her health.
Swiss-Army Weapon: It's a chainsaw! It's a cell phone! It's a grenade launcher, self-propelled rocket engine, or pair of pom-poms!
Juliet's boyfriend. 18 years old. After he gets bitten by a zombie, Juliet decapitates him in a desperate attempt to keep him from turning. His still-living head is kept on Juliet's person to give her emotional support whenever he's not lamenting his current situation. He can also take control of headless zombies for a short while thanks to Juliet's magic.
The main antagonist. 18 years old. A goth student from San Romero High School who opens a portal to the Rotten World and infests Earth with zombies to get even with the people who made his life a living hell.
A God Am I: Part of his ritual involves him declaring himself the god of the realm of Earth to the Dark Purveyors.
Hydra Problem/Me's a Crowd: Whenever she's cut in half, the two halves each turn into a whole Mariska. She even tears herself in half a second and third time after Juliet does for good measure. Juliet resorts to shooting down the copies.
