Nick O' Teen

Nick O' Teen is a tobacco additive and the main antagonist in the Ozzy & Drix episode, Where There's Smoke.

Nick entered Hector's body when Hector was pressured to smoke a cigarette. He entered with his henchmen: Butane, Carbon Monoxide, and Tar. He plans to brainwash the cells in Hector to follow his command so he can access the brain to take up smoking. The more cells he controls, the more powerful he becomes. While disguised as the lead singer of the band Metabolica, he managed to brainwash Mayor Spryman as well in the Air Fair. Nick was powerful enough to get to the pleasure center of Hector's brain. However, Hector chose to quit smoking in favor of Christine, his crush. Nick was weakened by Hector breaking the addiction and he was shrunk down so Ozzy can squash him under his shoe.

He was voiced by Tim Curry, who was also the voice of Scarlet Fever in the Pilot episode.
