Spark Plug is an overweight Nosedeenian, with the black and yellow coloring.
As opposed to other Nosedeenian, which are just mischievious for the sake of fun, Spark Plug seems intent on hurting people instead. He has been labeled as an "evil" Nosedeenian. He is considered dangerous and power hungry.
Grey obtains a device called the Electronizer, which allowed him to store the Nosedeenians while traveling. However, during this time, Spark Plug began to hate his "captor." When he was released to chase Ryder, he ignored Grey's orders to not harm him, and tried to kill him. He is sucked back into the Electronizer, now with a grudge.
When released for feeding, he revolted and took the other Nosedeenians, running amuck and draining energy, causing harm to the citizens of a town. Grey and Ryder worked together to re-capture him.
When Grey releases the Nosedeenians as a distraction for Ryder, Spark Plug sneaks away, chasing Ryder to get revenge. He is captured by Cooper of the SACT, and thrown into Area 51.
