I would like to put in for those of you who would just scoff at this dictionary, that this has been compiled from many many sources and I doubt you could find half of them on any one site. And in regards to the Cybertron-Earth time units, I spent multiple days going to different sites in an attempt to figure out the calculations, since only a few of the sites could really be trusted, so I had to try and fill in the gasps. I realize that some of the units of time may not add up to what it says on some sites but no other site I went to had a complete list of the Cybertron-Earth units of time. I am pleased to say that I think I was actually able to deciphered it. And in regards to the units of measurements, I realize that most aren't other sites and that's because I made up the majority of them. Oh and the ratio of human to transformers units of measure is 6:1.

All Spark - Cybertronian artifact said to be the source of life for all transformers; evidently has enough energy to become a weapon of mass destruction; also (alternately) the spark, or life essence, of Primus, to which all sparks return upon the deactivation of their bodies, hence the name.

Alternate Mode - The form of vehicle that a transformer can access after having scanned it holographically into his/her processor; variously abbreviated to alt mode or altmode.

Arn - A Cybertronian yard = 3 histers.

'Catching a nova' - Doing something incredibly stupid and is about to suffer greatly for it.

Carrier - One of the two creators of a sparkling; the one who actually carries the growing spark in his/her own body; how it is determined who should carry the new spark is uncertain, but it would seem that the one who is more feminine does.

Cerse - A Cybertronian mile = 1609 teks/1760 arns.

Charged - To be sexually excited; to be "turned on".

Chassis - The chest area.

Chest Plate - Armor covering the breast area; also called breastplate or asbergo.

Cybertron - Home planet of all transformers, a metallic world of super-advanced technology, residents and technologies of which are called Cybertronian.

Cyber Planet Keys - Gifts from Primus to his creations. The goal of the keys was to spread Primus' essence to other fledgling planets and reformat them in a way that would create new Transformer life forms. The keys were loaded aboard four starships - the Atlantis, the Ogygia, the Hyperborea and the Lemuria - and transported across the galaxy to four worlds selected to become Transformer colonies: Earth, Velocitron, Jungle Planet and Gigantion. Each key is a portion of Primus' life-force, and if gathered together and plugged into the Omega Lock, they can be used to awaken and restore him or give almost unlimited power to the holder.

Earth - Chosen as one of the planets to receive a Cyber Planet Key, which would have reformatted the planet into a transformer colony. However, the colony ship Atlantis, also carrying the Omega Lock, crashed onto the planet before it could begin its mission. Also when the Mini-cons fled Cybertron to escape being used as tools, their ship came out of warp above Earth. Impacting onto the planet's moon, the Mini-Con ship broke in half, sending a large chunk of the craft into Earth's atmosphere. Mini-con storage panels were spread across the globe and the ship itself crashed onto the surface, where they laid dormant for nearly a million years before being discovered by the human child Rad.

Ectodermis - The outermost layers of armor.

Energon - The preferred energy source for most transformers; has been alternately portrayed as food, intoxicating drink, ammunition, and currency; is found in underground mines in a solid form before being turned into a liquid stored in cubes, as this is the most stable form of the usually explosively volatile substance; quality and potency of energon apparently varies greatly, and is thus often described in degrees of quality called 'grades' (e.g., 'high-grade' to refer to energon with great potency); transformer equivalent of blood, along with mech fluid.

Energy Signature - Can usually be used to identify someone's faction. Also, certain substances or devices can mask a transformer's energy signature from detection.

Equilibrium Sensors - Helps a transformer keep their sense of balance.

Espe - A Cybertronian inch = 2.5 dunteks.


Faceplate - A protective piece of metal which covers all or some portion of a transformer's visible face, presumably for protective purposes; alternately, the actual surface upon which the transformer's facial features are located; see also mouthplates.

Gigantion - The planet is a huge machine world but constructed mostly by its inhabitants. Aboard the spaceship Lemuria along with a Cyber Planet Key, these Cybertronians, whose descendants have grown to tremendous size, settled on an Earth-like, rocky, organic-covered planet, and built their cities on it. As their skills increased, they continually rebuilt these settlements right on top the old ones, until the planet was completely enveloped in a vast series of constructed layers, complete with artificial foliage, simulated skies and day/night cycles - but at its heart, the original planet remains, well-preserved and even supplied with artificial light, but forgotten. The titanic transformers of Gigantion, large and powerful, are fortunately not much given to violence and warfare. Most are gentle and peaceful, desiring only to hone their skills and build even grander structures. They work closely with the small Mini-con, who can tackle the delicate tasks too refined for the heavy manipulators of their bulk comrades.

Glossa - Equivalent to that of the human tongue; equipped with the taste receptors.

Glitch - Problem or malfunction in programming or protocol; also general curse term, referring to a bot, generally equivalent in meaning to "idiot" or "moron"; also a form of the human swear word "bitch".

Hister - A Cybertronian foot = 12 espes.

Hyperborea - One of the four starships that left Cybertron with a Cyber Planet Key, bound for Jungle Planet.


Intake Manifolds - Equivalent to that of the human lung; works as a cooling mechanism for the body; does not need to breathe air like humans; usually shortened to intakes.


Jungle Planet - Sometimes referred to as the Beast Planet, is the simple and beautifully appropriate name for a lush and violent world covered in dense wilderness. Its surface is wrapped in tangled webs of foliage, some of it allegedly techno-organic, and vast, little traveled oceans. The light of day is harsh and scorching; the rains are torrential downpours. Volcanoes rise above the green canopy, usually slumbering in smoky menace, sometimes bursting forth with firestorms of destruction. Within the shadows of the enveloping jungle, strange beasts prowl; but not all these are of flesh and blood, for in ancient times the Jungle Planet became home to strange beings. They emigrated from the planet Cybertron aboard the Hyperborea with a Cyber Planet Key; they were transformers and quickly altered their forms to suit their new home. They prowl the Jungle Planet, and dwell in its caves and rough structures; robotic beasts of fearsome power.


Kibble - Seemingly unnecessary parts of a transformer's alternate mode that appear on his/her person in robot mode (i.e., door wings, wheels on heels, etc.).

Megacycle - A Cybertronian hour = 66 Cybertronian minutes (5.7 Earth hours).

Mini-Cons - A race of small, roughly human-sized Transformers capable of powerlinking with a larger transformer to impart extra abilities or greatly increase their strength. Unicron created the Mini-Cons to be mindless tools, sent to Cybertron as an agitating element to the transformers' civil war. The power-enhancing 'smart tools' would be unleashed upon the populace, who would snap them up and bond with them, and the war would only get more destructive, as Unicron drank in the negative psychic energies from the death and destruction. To escape being used as tools, the Mini-cons fled Cybertron their ship came out of warp above Earth. Impacting onto the planet's moon, the Mini-Con ship broke in half, sending a large chunk of the craft into Earth's atmosphere. Mini-con storage panels were spread across the globe and the ship itself crashed onto the surface, where they laid dormant for nearly a million years before being discovered by the human child Rad.

Mouthplate - A protective metal mask which covers a transformer's face from the jaw up to (and occasionally including) the "nose"; alternately, the Cybertronian idiomatic equivalent of human "lips"; see also faceplates.


Nanoklik - A very small amount of time.


Offline - Cybertronian dialect for "death"; as transformers are not technically "alive", they are said, when all their systems permanently shut down, to go offline; additional idiomatic equivalents include when one's 'spark goes out,' one is 'deactivated,' one 'crashes', etc.; also sometimes described as an equivalent to falling unconscious.

Ogygia - One of the four starships that left Cybertron with a Cyber Planet Key, bound for Velocitron.

Optic Lens - Protective glass that covers the optics located on the faceplate.

Omega Lock - The device that the Keys join with to reawaken Primus' power.

Organics - A term used by Cybertronians to refer to creatures of non-technological origins; this applies to all the different natural species of Earth, as well as other planets; the bipedal Earth organics known as humans have also been referred to as fleshlings, meatbags, insects, squishies, stubbies, noisy creatures, 'puny flesh creatures,' and 'dumb stubbies'.

Orn - A Cybertronian day = 20 Cybertronian hours (4.7 Earth days).

Overload - The release of energy through the body that occurs at the climax of an uplink; known to humans as an orgasm.

Plugging - To stimulate sexual excitement by use of the fingers on internal wires, circuits etc.

Powerlinking - When two or more transformers combine to increase in power, size, etc.

Primus - Cybertronian deity/personification of Cybertron itself; legend states he is the one who personally created the thirteen original Cybertronian transformers, as well as many others; eternal opponent of Unicron.

Protoform - The form a transformer possesses before he/she gains an alt-mode; also presumably a stage of the transformer life cycle similar to human childhood.

Recharge - The Cybertronian form of "sleeping".

Rintek - A Cybertronian millimeter.

Rotater Cup - The mechanism that enables shoulder movement; the sholder joint.

Servo - Limb on a transformer's body, generally equated to the human hand.

Stabilizing Servo - The transformer equivalent of the human foot.

'Shift gears' - Slang term to become or cause to become calm or less excited; similar to the Earth term to "cool it".

Slag - One of the most versatile slang terms in the Cybertronian vernacular; a vitreous mass left from the refining of metallic ores; can also refer to this mass while in its molten state, which floats atop the ore; a waste product; also a general curse term similar to the human word "shit".

Spark - The equivalent to the human heart and/or soul; it keeps the systems in the body functioning and is what makes transformers unique and individual; said to be a part of the essence of Primus.

Sparkling - An offspring spark which has been created by two separate creators ("gender" is irrelevant); a sparkling is a mixture of both creators; it is said that only the creators and immediate kin (siblings) can understand the garbled clicks and whistles of a sparkling, equivalent of a human infant.

Stasis Lock - The transformer equivalent to a human "coma".

Stellar Cycle - A Cybertronian year = 16 Cybertronian months (5.2 Earth years).

Taste Receptors - Receptors found on the glossa that enables taste.

Tek - A Cybertronian meter = 3.3 histers.

Transform - The act of a transformer changing from one mode to another.

Transformer - A species of sentient, living of robots originating from the mechanical planet of Cybertron; the title derives from the ability these robots have to change their shapes and forms from a primary mode to an alternate mode (mostly mechanical, vehicle, weapon, or animal in appearance and function); there are transformers with three or (extremely rare) four modes.


Unicron - The eternal arch-enemy of his twin brother Primus. He is known as the Dark God, the Chaos Bringer, the Planet Eater, etc. and he is dedicated to consuming the multiverse. His goal is to bring an end to the annoying creation boasting independence around him, and find peace by becoming the living center of a swirling infinite torrent of nothingness at the end of all things. Disguised as one of Cybertron's moons he implanted his own cells within the planet, where they germinated and grew into the small race of robots known as the Mini-Cons. Unicron hoped to use the Mini-Cons to increase the ferocity of the Autobot/Decepticon war, and feed off of the energies released in the conflict, but an encounter with a group of time-displaced human children planted the seed of sentience and free will within the Mini-Cons, who ultimately rebelled against their creator and fled Cybertron, crash-landing on the planet Earth.

Uplink - The Cybertronian equivalent to intercourse; how this is done has never been explained in any cannon form, though some fans have adapted this act to involve sparks rather then physical body parts; also called 'bond' or 'interface'.


Vocal Processor - The mechanism that allows speech; located in a transformer's "throat"; almost always shortened to vocals or voice.

Velocitron - Otherwise known as the Speed Planet, was colonized by a group of spacefaring, trailblazing Cybertronians aboard the starship Ogygia eons ago. Racing is the order of the day for the denizens of the Speed Planet, and if you're not a racer or working for a racer or watching a race, you're not a Velocitronian.


'What in the Matrix?'- Similar to the Earth term "what in the World?"

Well of All Sparks - The supposedly-mythical fount where Primus forged the transformers race; direct conduit for Primus' life-force and, therefore, the true origin of all transformers' sparks; said to be the place where a transformer's spark goes after he/she offlines; the Cybertronian parallel of the human "Heaven".


Youngling – A term for young Cybertronian who hasn't matured yet; equivalent of a human child.
