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. The symbols appeared all over ancient archaeological sites, from Egypt to Peru, indicating that Cybertronians had visited Earth before.
