Insignia/Gallery

Factions

Autobots

In the real world, the Autobot insignia was derived from the head of Prowl's toy.

Its in-universe origin varies: in Generation 1 cartoon continuity it was applied by the Quintessons to their "consumer good" creations, while in Marvel Comics continuity it is seemingly based on the Last Autobot. In 2005 IDW continuity it was "created" by Shockwave, who claimed it to be the face of Primus, as part of an ontological paradox.

Decepticons

In the real world, the Decepticon insignia was based on Soundwave's toy head. In the 1980s the crest of the symbol usually had a "squared-off" bottom, while modern portrayals generally have the crest pointed at the base.

Its origin in-universe is generally less-explored than that of the Autobots. In the Generation 1 cartoon continuity it was a symbol applied to the Quintessons' "military hardware", while in the live-action film series and Aligned continuity family it is seemingly based on the face of the Fallen.
