Main Cast

Professor Isaac Sumdac (Tom Kenny)

Father of Sari Sumdac, he is a good-natured but a bit of scatter-brained scientist who designs and tests robots at Sumdac Tower. He is incredibly slow on the uptake - Megatron is able to keep him satisfied with flimsy excuses, and when Bulkhead is ordering him around in a transparent attempt to keep him safe from Dirt Boss, even winking and explaining himself in private, Isaac still takes his cruel behavior as genuine. Fifty years ago, Isaac found Megatron after he crashed onto Earth. It is through studying Megatron that many of Sumdac's technologies are introduced. He is convinced by Megatron (who until now had been inactive and silent) to keep his existence from his "friends" (the Autobots) a secret until Megatron can get a new body built; unaware of the true origins and motivations of the Decepticon leader. While he did not like that Megatron added the fire-breathing capability to the Dinobots without telling him about it first, he was sympathetic in understanding that Megatron was simply experimenting with the Earth technology in order to make a new body for himself. But when he learned about the Decepticon's true origins, he was horrified and began to regret what he was doing. Before the event with the Allspark, it can be inferred that Professor Sumdac was going to tell Sari that she was a robot. After the events of "Megatron Rising" Pt. 2, Megatron is holding Sumdac captive, forcing him to help construct a Space Bridge back to Cybertron. He is also coerced into creating a dampener system that prevents the Decepticon's energy signatures from being detected by the Autobots. In "Autoboot Camp" he transmits part of Megatron's conversation with Shockwave to the Autobots, alerting them to the presence of the double agent, though the transmission was too blurry to show a clear image of the spy. In "A Bridge Too Close" Pt. 2, Isaac had to use a Headmaster unit to cut off Starscream's head so he himself could destroy Megatron, though this ultimately fails. He is eventually rescued in the end. When Sari notices robotic circuitry in her arm, Isaac tells Sari that they need to talk, and in "Transwarped" it is revealed that he found Sari as a Cybertronian Protoform which patterned itself after him; his initial encounter with Sari is also responsible for causing the white streak in his hair. At first, Sari is initially furious with him for withholding the truth from her. However, when he protected her from the Headmaster, they were able to reconcile. Professor Sumdac has been stated on numerous occasions to be a "genius" when it comes to reverse-engineering technology, and this seems to hold true.

Captain Fanzone (Jeff Bennett)

Captain of the Detroit police force who dislikes new, advanced machines, including the Autobots in general. He is in charge of the Detroit police force. His on-duty vehicle is a yellow sports hatchback, which was scanned by Bumblebee for his Earth mode. One of the recurring themes of his character is the destruction of his hatchback in one episode (by the Dinobots in "Blast from the Past" and by Blitzwing in "Velocity") and its sudden reappearance a few episodes later - all in the same beat-up condition. In "Total Meltdown", he is shown to be in charge of deciding which tech the police department will use, and has had problems with both Prometheus Black's bio-tech and Isaac Sumdac's robots. In "Survival of the Fittest", he was forced to team up with Prowl (who Fanzone later respects) and Bulkhead at the time when they went to Dinobot Island to investigate a lead on Sari's kidnapping which was orchestrated by Meltdown. His catchphrase, usually uttered when a machine malfunctions on him, is, "This is why I hate machines!" Despite his dislike for machines he has a somewhat friendly working relationship with the Autobots. He officially aids the Autobots (and Sari) in protecting the city of Detroit, (directly or indirectly) as a law enforcer. He is usually on hand to arrest the various supercriminals defeated by the Autobots. He is one of few "friendly humans" to have regular contact with the Autobots, besides Sari and Prof. Sumdac. His most recent adventure with the Autobots has him accidentally transported to Cybertron, along with Ratchet in "This is Why I Hate Machines".
