Dive whiskers-first into the bestselling graphic novel series about a new breed of superhero! In this action-packed box set, join Cat Ninja and his friends as he faces a variety of challenges, from scheming villains to babysitting and boredom.

Raised from a kitten by a kindly old ninja master, Claude now spends his days as the pampered house cat of an eleven-year-old boy. But when trouble arises, he dons his mask and springs into action as Cat Ninja—Metro City's secret protector! Follow Cat Ninja, Master Hamster, and a colorful cast of friends and foes in this box set containing the full 6-book series!

Book 1: Cat Ninja
Follow our feline hero's early exploits as he tries to keep his secret identity under wraps while thwarting the evil plans of slimy crooks, rampaging robots, and a certain rodent nemesis who lives under the same roof!

Book 2: Time Heist
When Leon brings a mystery egg home from school, Cat Ninja and Master Hamster face their biggest challenge yet: babysitting! And while they’re pretty sure they can keep an egg out of trouble, they know they’re in over their heads when that egg hatches into a high-energy ball of feathers and cuteness. It’s baby’s first superhero adventure when they decide to bring their newest family member along as they uncover the identity—and nefarious motives—of Metro City’s latest foe.

Book 3: Wanted
Metro City's favorites and newcomers in tales that include a nearly cat-astrophic case of stolen identity, the not-so-villainous adventures of Master Hamster, and Adonis's first mission as one of the good guys. Enjoy six stand-alone stories, plus a five-part Cat Ninja special miniseries!

Book 4: Welcome to the 'Burbs
When Dad buys a new house outside the city, the kids are less than excited about new neighbors, backyard barbecues, and quiet, tree-lined streets. And they’re not alone—a summer in the suburbs is enough to make Cat Ninja miss the villains of Metro City! Our hero and his family feel like fish out of water when they arrive in Peaceful Valley, but it won’t be long before Dad’s new neighborhood reveals its scaly, golden underbelly.

Book 5: Cat's Claw
When a notorious band of ninjas discovers a certain Metro City hero wearing their colors and practicing their Kat Fu, their leader sets out to settle an old score. Plus, a nocturnal ninja flaps into town, Octopunch puts up his dukes (all eight of ’em!), Adonis plays hero, Master Hamster’s creative kitchen repairs end with a scorching surprise, and our favorite frenemies-against-the-odds compete in the villainous Vroomin' Race!

Book 6: Heart of a Hero
It’s nonstop crime time in Metro City, and the hero the city needs is...Octopunch? Even an eight-armed avenger can’t keep the streets safe by himself, though, so Cat Ninja’s spending all his time catching crooks—and no time curled up with his family. When he realizes that Leon needs him more than Metro City does, it might be time to hang up the nunchucks. But with a brand-new baddie kidnapping every pest and pet in town, can our hero really afford to cat nap?
