Kaede Hiyashi is sick and tired of living in the shadow of his father, supervillain Doctor Terror. Brilliant but crazy, Doctor Terror sends his son to Corwyn, California, for reasons Kaede can't imagine. Sent to accompany and protect him is Ash, a genetically modified supersoldier raised and trained by an infamous death cult.

Corwyn is lousy with superheroes, led by the obnoxious Dark Justice. Kaede finds himself dancing around Dark Justice as he digs into his father's mysterious business and teaches his socially awkward—but physically lethal—bodyguard to acclimate to "normal" life. Can these two wacky supervillains figure out what Doctor Terror wants them to do, solve the riddle of the villain known as Black Hand, and keep Dark Justice from raining on their bloody parade? The course of love—and world domination—never did run smooth.
