Zack Arbutus Clarke: His house is a wreck, his sister's a zombie, and he's stolen his mom's Volvo. He's totally going to be grounded if he survives this zombie outbreak! Zack isn't the biggest kid on the block, but when the stakes are raised and there are lives on the line . . . let's just say, he steps up big in the clutch!

Johnston Rice (a. k. a. Rice): Zack's BFF, Rice is the Zombie Chaser's official know-it-all undead expert and wannabe scientist. He's practically memorized The Zombie Survival Guide, and he knows what's going on . . . most of the time.

Madison Miller: Zack's now zombified sister Zoe's BFF, Madison is a hotsy-totsy vegan queen; she's a cold-blooded mean girl with a heart of gold and a belly full of VitalVeganPowerPunch—and she seriously can't believe that her best friend became a zombie and left her alone with these dweebs (a.k.a. Zack and Rice)!

Zoe Archibald Clarke: Zack's sister, mean girl extraordinaire . . . she'll bite your face off and eat your brains, but only because she's a revolting zombie.

Greg Bansal-Jones: A world-class bully, Greg is the only person meaner than Zack's own sister Zoe. If you see this 8th grade superjock alone in the hallways, you better get lost fast, or you just may find yourself upside down in the garbage can . . .

Twinkles: Madison's zombified puppy, a half-Beagle, half-Boston terrier whose contagious bite is definitely way worse than his bark.
