Insignia

One of the universals across all Transformers continuities has been the use of Faction Symbols to differentiate members of respective armies, and sometimes even sub-factions within armies.

• Quintesson

• Ancient Autobot

• Ancient Decepticon

• Ancient Autobot/Decepticon

(Dreamwave continuity)

• War Within Autobot

• War Within Decepticon

• Autobot

(In G1 Comic continuity the Autobot symbol was based on the face of the Last Autobot. In the G1 Cartoon it was derived from the Quintesson slave brand) )

• Decepticon

(In "Real World" terms it seems likely that Hasbro designers based the Decepticon symbol on the head of Soundwave's toy. In the G1 cartoon the usual 3D detailing of the symbol was interpreted as a third spike in the center of the crest.)

• G.I. Joe

• Autobot (G2)

(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.)

• Decepticon (G2)

(The G2 Decepticon symbol seems to be a stylized, updated G1 Decepticon symbol. The Cybertronian Empire also used this symbol.)
