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

Prehistory

  Ancient Transformer

•

• 
  Fallen
  This symbol was only used on the Titanium toyline representation of the Fallen. It was not used in The War Within or any other fiction.

Pre-War Megatron Origin

• 
  Clench
  This symbol was worn by Clench and his team in Kaon's illegal pitfights prior to the Great War. After Megatron replaced Clench as team captain he retained the symbol for a time before developing the Decepticon insignia as his team emblem.
• 
  Security Services
  This symbol is used by the Autobot Security Services crew operating under Sentinel Prime and was seen on the flags draped over the coffins at the state funeral of operatives Fastback and Bumper.
• 
  Senate-related symbol
  This symbol was worn by the crew of Senator Decimus's ship, as well as by Ratbat during his senatorial days.

The Great War

• 
  Autobot
  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, it was known as the "Autobrand" and was seemingly based on the face of the Last Autobot. In the original animated series, it was a mark of the Quintesson slave brand.

• Decepticon It seems likely that in the real world, the Decepticon symbol was derived from a stylized drawing of Soundwave's toy's head. It has no given origin in either comic or cartoon, but in the latter, it presumably has the same origin as the Autobot symbol.

  The Decepticon symbol as it appeared on Generation 1 toy packaging. Note the bevelled detail in the center of the crest at the top - the model sheet of the symbol created for the G1 cartoon based on this version misinterpreted it as a third spike, and it appeared in the show rendered in this manner almost universally.
• Cybertron Guard This symbol represents the Decepticons under Shockwave's command charged with Cybertron's security. It was retroactively named in 2007 by TakaraTomy's World of Transformers website, but unnamed in its original context. Divide and Conquer

  Wreckers
  This symbol was used by the Wreckers in the 3H Wreckers/Universe comics, and debuted in 2001. It is uncertain if prior incarnations of the team used this insignia or if it came into use after the signing of the Pax Cybertronia. Departure

Car Robots

• 
  Takara used this symbol to represent the Combatron (Decepticon in Robots in Disguise) sub-group in Car Robots—it's an upside-down Generation 2 Autobot symbol, which had been molded into the Black Convoy toy, a redeco of Generation 2 Laser Optimus Prime. The Hasbro version removed them and used the traditional Decepticon symbol. Though it can be briefly seen several times in the cartoon, this symbol does not "exist" in the English version.

2007 movie

For the 2007 movie, the Autobot and Decepticon factions were rendered in the steely gray seen below. Additionally- the Autobot and Decepticons were strongly associated with the colors blue and red, which led to the Autobot symbol appearing in blue in multiple media. Nonetheless the 'official colors' of said symbols remains red and purple.

• 
  Autobot
  The biggest change is that the tops of the eye sockets, horizontal in the G1 symbol, tip down towards the middle in the Movie symbol. There are other minor differences in proportions and angles.
• 
  Decepticon
  The G1 symbol has triangular eyes, as opposed to the skinny diamond eyes in the Movie symbol. Again, there are other minor differences.
