Wendy and Marvin meet a stray dog that Miss Martian names Wonder Dog. In reality, Wonder Dog is some sort of demonic monster in the service of a new villain called King Lycus, who appeared at the end of the issue after the beast has killed Marvin and severely mauled Wendy. While comatose, Wendy is visited in this state by her father, Noah Kuttler (a.k.a. the Calculator), who swears revenge on the Titans for allowing this to happen to his children.
