The Decepticon and Autobot logos have been around since the first iteration of the Transformers toys in 1984. Both have become equally recognizable, with the Decepticon logo now synonymous with evil. However, its symbolism goes a step further than their enemy, the Autobots, as it is a deliberate representation of their identity due to being inspired by the coldest and most calculating Decepticon ever, Soundwave, no matter his iteration. Consequently, the logo is imbued with layers of meaning, adding depth to the Decepticons' placement in the overarching Transformers universe.
