Primacron is ancient alien scientist from the Transformers G1. He is the creator of Unicron and Tornedron. Despite that he is not purely evil, he can be considered as a villain due to his jerky tendencies of creating planet destroyers for galactic domination. He appeared in the episode "Calling of the Primitives".
He was voiced by the late Philip L. Clarke.
Prior to the events of the series, Primacron's assistant created a group of Transformers called "Primitives". Primacron grew jealous of him and out of ambition, he created Unicron, who then rebelled against him by destroying his assistant, who later became The Oracle and injuring Primacron.
Millions of years later, Primacron returned for his conquest of the universe again. This time, he created Tornedron, a shapeless giant siphoning energy monster. He ordered the huge beast to drain energy from various planets alike and later on the Primitives who were assembled to defeat him. After successfully draining the Primitives, Tornedron left to return to its master. Unknown to it, Grimlock had secretly survived from being crushed by a drained Trypticon and secretly followed the energy drainer.
Upon Tornedron's return, it then turned against Primacron and tries to destroy him. Grimlock then breaks into Primacron's lab, seeing the latter is a small alien resembling a monkey fish. The Dinobot leader grabs Primacron and orders him to undo the damage he had cause but explains he tried everything but failed. Grimlock then finishes the job by throwing the reverse switch, undoing Tornedron's energy polarity, killing it in the process and restoring life on every part of the galaxy Tornedron went. To make such he doesn't do anything stupid again, Grimlock then celebrates by destroying Primacron's computer, much to the alien scientist's horror, while claiming it is the "smartest" thing he has ever done.
- Though not a medium, it may be possible that Primacron could be one of the Creators in the Transformers film series.
- It is unclear whether both Primacron itself and its assistant Oracle, or at least only Oracle may somehow truly being associated with/once working alongside Quintessons at one point in their lives as they only appeared in one episode and is responsible for Unicron's birth that made him part of Transformers mythos as they have influential impact on Cybertronians' history until today. Even in this site, it was jokingly hoped never will truly answered.
