The Bionic Booger Boy is really Melvin Sneedly after an experiment gone awry. Melvin first attempts to combine himself with a robot, so he will intimidate George and Harold. However, he sneezes at the last second and he, the robot and his snot are combined, resulting in the birth of the Bionic Booger Boy. Later, Melvin freaks out on a trip to a tissue factory and when he is offered a pack, he grows gigantic and destroys the factory. He then tries to kill George and Harold but Sulu beats him up. Later, Melvin's parents appear and reverse the mess, seemingly restoring their son. However, Melvin and Mr Krupp have swapped bodies and the Combine o Tron is then destroyed by the slowly forming Robo Boogers.
