Insignia
One of the universals across all Transformers continuities has been the use of insignia to differentiate members of respective armies, and sometimes sub-factions within armies or even individuals.
Generation 1
- Ancient Transformer
This is an ancient symbol that Shockwave found in the G1 Dreamwave comic. Although Transformers have been split into two races, they are one species, he claims.
It seems likely that in the real world, the Autobot symbol was derived from a stylized drawing of Prowl's toy's head. In the Marvel Comics continuity, the Autobot symbol was seemingly based on the face of the Last Autobot. In the original animated series, it was a mark of the Quintesson slave brand.

- Autobot (ancient)
- Autobot (War Within)
It seems likely that in the real world, the Decepticon symbol was derived from a stylized drawing of Soundwave's toy's head. The model sheet of the symbol created for the G1 cartoon misinterpreted the bevelled detailing of the top of the symbol as a third spike in the center of the crest, and it appeared in the show rendered in this manner almost universally.

- Decepticon (War Within)
- EDC (cartoon)
- EDC (Dreamwave)
Used by Ratbat's group in The War Within era
G.I. Joe Crossovers
Generation 2
- Autobot
The G2 Autobot symbol seems clearly based on Optimus Prime. In the Marvel Comics continuity this change may have occured since the Last Autobot had come and gone.
This symbol was used by Jhiaxus's Cybertronian Empire, who considered themselves neither Autobot nor Decepticon.
- Decepticon
The G2 Decepticon symbol seems to be a stylized, updated G1 Decepticon symbol. Bludgeon's Decepticons adopted this symbol around 1991, apparently unaware it was also being used by the Cybertronian Empire that they would soon encoutner.
Beast Era
- Maximal (Beast Machines)
From IDW's Beast Wars comic books
- Predacon (Timelines)
Worn by Razorclaw in Dawn of Future's Past.
- Seacon Space Pirate

Robots in Disguise
- Japanese Decepticon
Takara used this symbol, to represent the Decepticon (Combatron) sub-group in Car Robots- it's an upside-down G2 Autobot symbol, which had been molded into the Scourge toy, a redeco of G2 Laser Optimus Prime. The American version removed them, and used the traditional Decepticon symbol. Though it can be briefly seen in the cartoon, this symbol does not 'exist' in the American version.
Unicron Trilogy
- Team Ironhide
2007 Movie
A Secret organization on earth that is trying to save humanity from the Autobots and Decepticons.
