Logicon

I'm sorry, sir, you didn't see an alien. What you saw was merely a weather balloon.

The Logicons exist in a state of logic and harmony on the planet Metascan Alpha.

Fiction

Transformers in 3-D

Eons ago, the Logicons were part of a war to defeat the four Destructons. Once the Destructons had been contained, the Logicons imprisoned them in a dimensional barrier on a desolate world. Near the twin spires which controlled the barrier, they placed a warning beacon, containing information about the Destructons and the coordinates of Metascan Alpha.

After the Destructons were freed, the warning made its way to the Autobots. Ultra Magnus took a team to the planet described on the tape, only to find a rapidly evacuating city under attack by the Destructons. The War Against the Destructons, Chapter 1 of 3

Beast Wars: Uprising

Existing in the long forgotten past, the Logicons were a race of knowledge gatherers. They eventually established a colony on the planet Metascan Omega where they constructed a ziggurat to hold all their knowledge for any beings who wished to access it, before they ascended to a higher plane of existence as beings of pure energy. Rumours of the vast knowledge that the Logicons once possessed drew Lord Imperious Delirious to Metascan Omega. Intersectionality

Notes

• It's unclear if the aliens in the city Ultra Magnus's team finds are Logicons, as they don't resemble the one seen in the recording.
