Captain Amazing, the hometown hero of Metro City, is searching for a sidekick!

Heroes near and far are auditioning for the part, but there's four unlikely candidates heating up the competition. A dog, a cat, a hamster, and a chameleon -- the adoring pets of Captain Amazing's alter ego, Harry -- have all been honing their own secret superpowers. Wanting to spend more time with their beloved human, each pet is vying for the coveted role.

Meanwhile, Dr. Havoc is back and Captain Amazing can't defeat him on his own, leaving Metro City and its citizens in serious danger. Can the warring pets put their squabbles aside to save the day?!
