In this nearly all-dialogue series-opener, a quintet of young superheroes with unusually kidlike powers squares off against a noise-hating mad scientist. Despite continual efforts to keep it down, Daniel is cursed with such loud pipes that no window or water glass is safe in his presence. This earns him a quick detention in his new school, where he meets three fellow fifth-graders with their own exaggerated abilities to annoy: Rex Rodriguez instantly breaks anything he touches; Violet Fitz can produce world-class tantrums; and Sid Down raises hyperactivity to high art. As it turns out, all four were test subjects as newborns, exposed to a defective “Behavio-Ray” that was supposed to make them permanently docile but had the opposite effect. Now the ray’s developer, Otis “Old Fogey” Fogelman, is back with an improved product, and plans to try it out on the entire planet—starting with his first batch of failures. Joined by Daniel’s babbling little sister Jeannie S. (who lives up to her name), the young folk do brisk battle in brightly colored, easy-to-“read” cartoon frames, win a victory and by the end have not only cool new names like “Tantrum Girl” and “Destructo Kid,” but even a clubhouse. Stay tuned for further world-saving. (Graphic fiction. 8-10)
