Caretakers of the Teen Titans
During the DCU's lost year, Wendy and Marvin work as the caretakers for the Teen Titans. With their intelligence, they also provide tech support at the Titans Tower. They were the ones responsible for fixing Cyborg, while he was offline for the year.
As their time with the Titans progressed, the duo began feeling more like janitors and expressed desire to leave the team behind. But when a lovable dog finds his way into the Tower, they dub him "Wonderdog" and their attitudes begin to change with a new sense of purpose. However, the dog was actually sent to infiltrate the Tower by the villainous Lycus. Both Marvin and Wendy attacked by Wonderdog, who is actually a vicious beast. Marvin is killed. Wendy survives, though she is comatose. The Calculator visits her in the hospital, and reveals that he is her father.
Wendy's story is continued in Oracle: The Cure #3, in which Wendy recovers from her coma. However, she is unable to feel her legs, suggesting that she is paraplegic.
