What's the worst that could happen at the school science fair? Too much vinegar in the clay volcano? Not when all-new villain Madcap's entered. And when a stricken friend is taken to the hospital, the journey is violently interrupted by yet another new baddie, Mudslide. Who is pulling his strings? What's going on here? The answers to these questions and more can be found in this pulse-pounding fourth issue brought to you by Wayne Osborne and John Byrne.
