Morton Fizzback (voiced by Brian Cummings) a sleazy and greedy concert promoter who is notorious about scheming to make money off anything.. or anyone. Ever since Fizzback first laid eyes on Denver, he has been developing various schemes to kidnap and make a profit off the dinosaur.
The pilot episode was Fizzback's only successful attempt at kidnapping Denver. Fizzback placed Denver in a dino themed rock band called "The Rockin' Dinos", but before Fizzback could put Denver and the band on a world tour starting in Japan- Mario, Shades, Jeremy, and Wally snuck into the concert and sucessfully got Denver back. In this episode, Morton is credited in creating Denver's theme song (the cartoon theme song).
