Cybertronian language

It should be little surprise, given a moment's thought, that distinct Cybertronian languages exist. The Transformers did not go about speaking English or any other known Earth language long ages ago on their distant metal world. Though the records of such conversations are frequently translated for us, we should not forget that these conversations originally flowed in odd electronic sylables past strange metalic lips, or were etched by alien hands long eons before the first humans painted muddy shapes upon dark cave stone.

Generation 1

Marvel Comics

Runamuck and Runabout sprayed Cybertronian grafitti across Earth monuments.

Animated series

So it's true. The Pyramids were built by aliens.

The first language used by the Transformers was likely the Quintesson language inherited from their former masters. It can be seen upon the walls of the Quintesson dimensional transporter room. It rather resembles Egyptian heiroglyphs. Madman's Paradise

Ancient Autobot, on the other hand, eschewed pictures of birdies

Ancient Autobot was the language used by the ancient Autobot colonists that fled Cybertron in the distant past. Most modern transformers could not read it. Cosmic Rust

The controls of the Plasma Energy Chamber were labeled in Ancient Cybertronian, which Spike Witwicky did not recognize but Cerebros was able to read. The Rebirth, Part 1

Beast Wars

Cybertronix is the name of the modern written language of the Maximals during the Beast Era. Whether this is the same language spoken on Cybertron durring earlier portions of the Generation 1 continuity or at all similar to that written and spoken aloud in the live action Transformers Movie is unknown. As it is specifically refered to as the "modern written language," it seems likely that there were other Cybertronian languages, with other names, at some point in the past. The computers on the Chromia 10 label displayed planets in Cybertronix. Razor's Edge

(NOTE: Although the name was never given canonicaly until Razor's Edge, Cybertronix was the name Larry DiTillio and/or Bob Forward gave to the language used by their characters in Beast Wars, as first stated in a post to alt.toys.transformers on January 1, 1997 [1]. This post indicates that Cybertronix is the name of the spoken language as well as the written, and that both the Maximals and Predacons speak it.)

Beast Machines

While in the big floating head, Megatron took to addressing people as a hologram composed of Cybertronian symbols, possibly Cybertronix. The symbols took the form of a big floating head. Real original there, Megs.

Transformers (2007) movie

Rather unique in this continuity several Transformers (notably Optimus Prime and Megatron) have Cybertronian words etched onto their heads, near the cheek area. What they say is anyone's guess (Would have been a darn good question to float around at Botcon though). The Transformer's cometary Transition forms also seem to be convered in a lot of Cybertronain writing, meaning unknown. The All Spark was covered in Cybertronian glyphs, leading Sector Seven to conclude a connection between the All Spark and Megatron.

The Decepticons communicate in actual Cybertronian when speaking among themselves on Earth, but have learned enough English to communicate with the humans when necessary.

(The written version of Cybertronian appears now and again throughout the film, most obviously during Decepticon dialogue, where the subtitles will be displayed in Cybertronian briefly before translating to English.)
