A gray-haired Caucasian man in a yellow lab coat.
"Peril of the Reptilian"Edit
Simon was Dr. Phorbus' faithful assistant. When the Quests arrived on Phorbus' island, Simon and Patch were sent to "welcome" Dr. Quest and Race Bannon. They brought them back to Phorbus' compound. Afterward, Simon and Patch took Race out at gunpoint and left him to be eaten by the tyrannosaur hybrid, which subsequently attacked the compound after Race, who had escaped thanks to Jonny Quest and Hadji, sabotaged the forcefield generator.
Simon, along with Patch and Phorbus, was buried when the ceiling of the main lab caved in on them.
Simon was voiced by Barry Dennen.
