Cybertronian Language

While some Cybertronians speak English, like many humans, they can also speak, read and write in their native language.

Transformers: War for Cybertron
On many computers, consoles, and screens on Cybertron, Cybertronian scripts could be seen. When a directive was shown to a Transformer, symbols flashed on their heads up display.

"T.M.I."
When Bulkhead's mind started to be assimilated by information ejected from a data cylinder, his mind went to science and formulas. He began to eccentrically paint Cybertronian symbols on chalkboards and walls, using a broom like a paintbrush.

"Persuasion"
Raf knows how to decode Cybertronian code since Ratchet taught him.
