Primacron

Primacron is an fish-monkey alien from the Generation 1 continuity family.

There are some things man just wasn't meant to know!

Primacron is an absolutely ancient scientist. He's supposedly hyper-intelligent with an infinity of intricate plans nested within plans, but he sometimes over-thinks things to the point of coming off as rather dim.

His major claim to fame is being responsible for building Unicron at the dawn of the galaxy. Thanks for nothing.

Fiction

Generation 1 cartoon

Voice Actor: Hal Rayle (English), Keiichi Nanba (Japanese)

Primacron's Assistant claims that they built some of the "primitive" Transformers way back then. As he grew more ambitious, Primacron eventually constructed Unicron, who rebelled against him. Unicron's attack appeared to destroy the assistant and badly injured Primacron.

The little ape-lizard was down but not out. Not to be undone by a giant planet-devouring robotic monster, Primacron returned millions of years later to try the whole conquest thing again. This time, he created the giant energy-siphoning monster Tornedron. The same thing proceeded to happen again and the little bugger would have been toast, if not for Grimlock's simple instincts (which somehow told him to reverse the polarity). Grimlock then proceeded to wreck his lab, hopefully beyond repair. Call of the Primitives

Notes

• When first telling their story, the assistant calls him "the being we will refer to as Primacron" and later calls himself "The Primacron's assistant". These seem to suggest that "Primacron" may actually be some sort of title and not this creature's actual name.
• Many points in the episode open large questions about how they relate to previously established history. Included among these are which primitives did he build, how Primacron relates to the Quintessons, to Vector Sigma, to his Assistant, to the Matrix, and the Primus/Unicron mythos. None of these questions have ever been answered, and hopefully never will.
• In Stormbringer #2, Scoop uses the phrase "Primacron knows" as a stand-in for the English language phrase "God knows". What significance, if any, Primacron has in IDW continuity is unknown.
• Primacron's lab is on the moon Protos, according to Transformers Animated: The AllSpark Almanac Volume 2.
