Move over Maximum Boy, there's a new superhero in town. And not only is he handsome, loyal, and brave, but his voice has changed! Super Sid is fifteen years old, complete with muscles and athletic ability. (And to be honest, umm, our eleven-year-old hero has arms like twigs.) To make matters worse, when Sid turns on the charm, even Max's family is captivated by those pearly whites. Tiffany may have her biggest crush EVER, but Max suspects an imposter. Is Super Sid really as spectacular as he seems?
