Heroes • Jack Tenrec (voiced by David Keeley) is a survival-savvy garage
mechanic who is a member of the Old Blood Mechanics. Jack has a passion for restoring classic car shells (mainly those of
Cadillacs) which the Mechanics use as their mode of transportation. • Hannah Dundee (voiced by
Susan Roman) is a foreign
ambassador from Wasoon who is Jack's constant companion and love interest. She is often on a mission to stop Jack from running his enemies into his neighbors' territory. • Mustapha Cairo (voiced by Bruce Tubbe) is Jack's companion who often helps Jack in his endeavors. He is an engineer. • Kirgo (voiced by
David Fox) is a ferryman associated with the City in the Sea and a friend of Jack. • Hermes is a juvenile "Cutter" (
Allosaurus) that was raised by Jack. Although he is gentle towards Jack and Hannah, Hermes can still be rather fierce when angered. Villains • Council of Governors is a council that rules the City in the Sea. • Governor Wilhelmina Scharnhorst (voiced by
Dawn Greenhalgh) – corrupt, power-hungry, and uncaring of the balance of nature, Wilhelmina is one of the three governors in the City in the Sea, and Jack's
nemesis. Wilhelmina has hired Hammer Terhune and his gang to do her dirty work. Despite her callous nature and disdain for Jack, whom she sees as an obstacle to her rise to power and to humanity's dominance as a whole, Wilhelmina only wants what's best for her city and knows when to respect Jack, though it's usually only when doing so will benefit her interests as well. • Governor Dahlgren (voiced by Kristina Nicoll) is a female who is the voice of reason to the governors. Her governing styles are said to have been heavily influenced by Jack. • Governor Toulouse (voiced by Philip Williams) is the public relations man of the governors. His concerns all lie on the morale and attitude of the public regarding potential problems. Even though Toulouse means well, he is not used to the outdoor lifestyles of Jack Tenrec. • Nock (voiced by Don Dickinson) is the Captain of the Guards in the City in the Sea. He is one of the people who have a dislike for Jack Tenrec. Nock is a sycophant and a very corrupt officer, obeying Scharnhorst without caring if she is wrong, lying any time and to anyone he deems convenient, and even trying to pull off scams. • Dr. Fessenden (voiced by
John Stocker) is a
mad scientist who would often invent some technology for Wilhelmina to use, particularly
radio-based gadgets (his name coming from radio pioneer
Reginald Fessenden). • Hammer Terhune (voiced by Ted Dillon) is a burly poacher who would often attack Jack Tenrec. Although he was hired by Wilhelmina Scharnhorst, he shows no respect to her unless she has some technology for him to use and would betray her if he sees a chance. • Wrench Terhune (voiced by
Colin O'Meara) is Hammer's younger brother who wears a headband. • Vice Terhune (voiced by
Frank Pellegrino) is Hammer's younger brother who wears a ponytail. • Mikla (voiced by
Lenore Zann) is a female who is a member of Hammer's gang. Allies • Griths are a race of
lizard men who reside in caverns. • Hobb (voiced by
Don Francks) is a Grith who serves as Jack's translator to the Griths due to his telepathy. • Wild Boy is a
wild child raised by the Griths that wears a loincloth and animal hide boots. He does not speak any human language, but can communicate with the dinosaurs. The Griths raised the Wild Boy ever since saving him from the cave hyenas. He first appears in "Wild Child" where Jack and Hanna discover him and try to keep him out of Hammer Terhune's clutches while returning him to the Griths. In "Duel", the Wild Boy later brings Jack and Hannah to the Griths at the time when Jack's old friend Sean has stolen their . • Adamus (voiced by David Fraser) is a powerful ally who's part man and part machine.
