Ben, Gwen, and Kevin set out on their mission to locate the other Plumber’s children to recruit new members for their team. The first one they encounter is a young man named Michael Morningstar. Since Michael has all the Plumber’s gear of his late father, as well as the fact that he seems to have been helping his city using his yellow-colored energy-controlling abilities, Ben and Gwen are quick to trust him. Kevin, however, remains suspicious (partly because of Gwen’s romantic attraction to Michael). Seeing a reading on Michael’s computers that there’s a massive power draw at a local power plant, the team plus Michael decides to act. Finding a group of zombified school girls at the plant, the team engages in a short battle, and Michael ”accidentally” lets them escape. Michael asks Gwen to dinner. Ben tries to stop him, but Kevin uses the opportunity to break into Michael’s house to see if his suspicions are valid. As it turns out, Michael is making the zombies, draining the schoolgirls of their vital life-force energy and then commanding them to collect more strength for him. Fearing for Gwen’s safety, they unfortunately arrive to help her too late. Michael drains Gwen’s own magical abilities and becomes nearly unstoppable. With Ben and Kevin knocked out, Gwen saves the day by fighting back and comes to her senses by reabsorbing her abilities. Weakened and drained, Michael is then attacked by the school girls, leaving him withered and powerless.
