The current leading expert in robotics, Vivian found it difficult to be taken seriously as a scientist when she looked like a supermodel.
She worked with Dr. Fenn to design a lunar exploration probe, which she took once she found out he was going to take all the credit. Fenn reported the robot as his stolen property in order to hide his own failures in robotics. In the end she is offered a job at the Middleton Space Center by Dr. James Timothy Possible.
Vivian is a very intelligent woman, who has designed robots for the Middleton Space Center. These robots were equipped with advanced technology, such as artificial intelligence (the robot learning as it goes) and self-preservation (sensing danger and defending itself). It can be assumed that she turned out be an asset to the Middleton Space Center, when Dr. Fenn was arrested.
