The Cyberglyphics are an ancient form of writing symbols or the Language of the Primes, seen on Transformers: Megatron, Optimus Prime, and Soundwave. Most Transformers have a symbol on them somewhere. However, younger Transformers don't know how to comprehend or know the meaning of these such symbols and can't read them like Mudflap and Skids. Starscream has the symbols all over the top of his disguise jet form.

After touching a piece of the All Spark, Sam begins to see the symbols, being a kind of map to an Energon source and the Matrix of Leadership located in the Tomb of the Primes, that can help him find the Solar Harvester. Megatron who wants to have the information that Sam has on his mind, so he and his Master can activate the harvester and claim Sol's Sun. Seekers, like Jetfire, can read these symbols and were sent by The Fallen to find the solar harvester and the Tomb of the Primes to find the Matrix of Leadership then report back to The Fallen.
- The symbols are hard to see in the movies, but if you know where to look you can see them, but they can be seen on concept art and the box art of games.
