 Kim s father calls on her skills to help recover a robot that was stolen from a top-secret deep-space project, headed by a Dr. Phen, who doesn t really seem adept at handling robots. The prime suspect is his former lab partner, Vivian, a gorgeous blonde. She is rumored to be hanging out at The Robot Rumble, where robotics hobbyists design battle robots and have them fight. Kim s cousin Larry gets Kim and Ron into the Rumble, where she confronts Vivian. Vivian s boyfriend, Oliver, is angry at the accusation and challenges Kim s robot (her Kimmunicator) to a fight. Even with Wade piloting it, Oliver s robot crushes it. It s then that Kim realizes that Oliver s robot is the one that was stolen from the Space Center. Kim and Ron sneak back into the Robot Rumble HQ when all the humans have left and take Oliver s robot and return it back to Dr. Phen. Back home, Kim s brothers are working on a robot for the Rumble, but its programming needs much work. Their father comments that sometimes they re just like Dr. Phen - totally clueless. Kim then realizes that Phen didn t invent the robot, and she heads back to the Space Center. Once there, they find Oliver challenging Phen for the robot. Phen admits he didn t invent it, but because he s got the reputation, he s the one that will be believed. He runs out of his lab, but Kim gets the robot back by turning on a powerful electromagnet. But besides attracting the robot, Oliver is also picked up by the magnet; Oliver is also a robot. Ron confusedly asks who built Oliver, whence Kim reveals that Vivian is actually a noted robotics expert, Dr. V.F. Porter. Once Phen is reveals as a fraud, Dr. Possible offers Vivian a job heading the robotics project, to which she gleefully accepts.
