Mooch is like all other flies, except that he was made by Ben, so he is sort of like a robot fly. He serves as the G-Force team's surveillance specialist. In the beginning of the movie, Mooch is seen using a sensor device to spy on Leonard Saber and his Clusterstorm project. Mooch is later seen when he was trying to wake up Ben to tell him where Darwin, Juarez and Blaster were. Ben thought that Mooch was an ordinary fly, and he nearly squished Mooch by accident before realizing who the fly was. Mooch assists Darwin by giving him the virus-infected PDA, which Speckles uses to shut down his deadly Saberling robot that he created by the other Saberling Appliances. Mooch is last seen celebrating with the guinea pigs on a successful mission.
