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.
Generation 1
- Ancient Autobot
- Ancient Decepticon
- Ancient Transformer
(This is a symbol that Shockwave adopted in the G1 Dreamwave comic book. Although Transformers have been split into two races, they are one species, he claims.)
- War Within Autobot
- War Within Decepticon
- Ultracon
(Used by Ratbat's group in The War Within era)
- 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 Crossovers
- Cobra
- G.I. Joe
- Decepticon/Cobra
Generation 2
- Cybertron Federation
- 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.)
