Cybertronian

The Cybertronians (more commonly known to the Human race as Transformers) are a species of autonomous robotic life forms originating from the artificial planetoid Cybertron.

Anatomy
Cybertronians are a machine race that carries a "spark" inside their bodies. As long as this spark endures and remains intact, the Cybertronian can be rebuilt, no matter how much damage the unit has sustained. If the spark is extinguished or otherwise destroyed in some way, the Cybertronian cannot be rebuilt and remains permanently dead.

Various subspecies of Cybertronians exist, inhabiting colony worlds sponsored by the Thirteen Primes. These include Velocitronians, Camiens, Animatronians, Gigantions, Aquatronians, Combatronians, and Mutacons

Headmasters
Headmasters are small symbiotic Cybertronian-like lifeforms that transform into the heads of larger robots. They are frequently but not exclusively organic.

Headmaster bonding typically occurs between two sentient beings, but there have been cases in which either the head or body is a Transtector, a non-sentient construct controlled entirely by the other partner.

There also exist Titan Masters, who function similarly to Headmasters except they are additionally compatible with Titans.

Targetmasters
Targetmasters are Cybertronians binary-bonded to smaller partners that can transform into their ranged weapons. The partner is often an organic life form that has either been bio-engineered to be partly mechanical or wears a suit of armor that transforms around them to become the weapon.

There also exist Battle Masters, who function similarly to Targetmasters except they are also compatible with the C.O.M.B.A.T. System. Many Targetmasters can be classified as Battle Masters.

Other Battle Masters can transform into melee weapons in the vein of some Action Master partners. There are even Battle Masters who transform into shields that double as A.I.R. Lock System-compatible ramps.

Mini-Cassettes
Mini-Cassettes (also known as Cassette Warriors, Infiltration Troopers, or simply Cassettes) are Mini-Cons and other small Cybertronians with audio cassette alternate modes. They generally can fit into the chest compartments of Cybertronians such as Soundwave and Blaster.

Cassettes have different types of robot modes, with the most common ones being humanoids, condors, and jaguars. For example, Rumble, Frenzy, Rewind, Eject, Rosanna, Flip Sides, Enemy, and Playback are humanoid Cassettes; Laserbeak, Buzzsaw, Sundor, and Garboil are condor Cassettes; and Ravage, Stripes, Howlback, and Glit are jaguar Cassettes.

There also exist dinosaurian Cassettes, with Dile/Dairu and Uriad both being Iguanodons, Zaur/Zauru and Uruaz both being Apatosauruses, Overkill being a Ceratosaur, Slugfest being a Stegosaurus, Graphy being a Pteranodon, and Noise being a Allosaurus.

Other types of Cassettes include lions such as Steeljaw, rhinoceros such as Rhamnorn, bats such as Ratbat and Wingthing, eagles such as Squawktalk, and gorillas such as Beastbox.

Weaponizers
Weaponizers refer to two different types of Cybertronians. The first is a group of genetically modified Mini-Cons from the Uniend cluster who are transform into weapons, much like Targetmasters and Battle Masters.

The second is full-sized Cybertronians from the Primax cluster that can split apart into C.O.M.A.T. System-compatible weapons for their comrades. Known Weaponizers of this variety include Cog, Brunt, Slammer, Fasttrack, and Six-Gun.

Modulators
Modulators are Cybertronians who can split apart into A.I.R. Lock System-compatible bases for their comrades. Known Modulators include Ironworks, Airwave, Hot House, Greasepit, and Overair.

Fossilizers
Fossilizers are Cybertronians infused with primordial energy who can split apart into F.O.S.S.O.L. Technology-compatible weapons for their comrades. They get their name from being able to transform into skeletal prehistorical beasts. Known Fossilizers include Paleotrex, Ractonite, Wingfinger, Tricranius, Spindle, and Masterdominus.

Action Masters
Action Masters are Cybertronians who lose their transformation ability due to the fact that their figure alteration systems got converted into energy storage reactors from using Nucleon as a fuel source.

Action Masters are equipped with transformable partners and vehicles to aid them in battle. The aformentioned partners that are able to transform into melee weapons can alternatively be identified as being Targetmasters.

Ecology
Cybertronians primarily consume a rare substance called Energon, which serves as both a fuel and their "life force". In its raw form, Energon is actually harmful to them, although not to organic life. In its processed form, Energon is essential to a Cybertronian's survival.

Powers and abilities
A Cybertronian's primary ability is the "art" of transformation, in which they assume an alternate mode that grants them increased mobility. Alternate modes can also be used for stealth, as they can disguise themselves as unassuming machinery.

With the necessary equipment, Cybertronians can alter their appearance by scanning different vehicles. Technically speaking, nearly all Cybertronians possess this ability.

Because they do not need to breathe, Cybertronians can survive underwater and in the vacuum of space.

Cybertronians possess superhuman strength while in robot mode and superhuman speed while in vehicle mode.

Cybertronians possess enhanced agility and reflexes in both robot and vehicle mode. These abilities can be enhanced by the Headmaster binding process.

A Cybertronian's body has natural armor made from a special alloy that allows them to withstand most conventional attacks and certain alien technologies. They also have a limited self-repair system to fix minor damage.

Cybertronians can not only access built-in weapons, but they also utilize external weaponry. Their targeting accuracy can be enhanced by the Headmaster binding.

Cybertronians with aerial vehicle modes are capable of flying in robot mode using kibble from their alternate mode, such as jet thrusters and helicopter rotors. Similarly, Cybertronians who can transform into birds, insects, and avian reptiles can fly in robot mode using their beast mode's wings.

Because they are not exactly natural lifeforms, Cybertronians do not have a natural predator. For example, Archa Seven Arachnids are not considered a natural predator to Cybetronians.

During a Headmaster procedure, the smaller partner gains control of a larger and more powerful body, whereas the Transformer gains an extra perspective on the battlefield. This psychic binary bonding allows them to draw on both their own ideas, tactics, and instincts as well as those of their smaller partner as quickly as if they were coming from their own head.

A Titan Master procedure behaves similarly to the Headmaster procedure, except the Titan Master also possesses a unique Spark that allows them to transfer their innate powers into the bodies of larger Cybertronians.

Targetmasters benefit from being able to take two minds into battle by possessing a living weapon capable of making its own tactical decisions and target priorities. The advantage is similar to that of having a dedicated gunner aboard an aircraft or tank.

Similar to the aforementioned Targetmasters, Battle Masters can they provide adequate firepower for their larger partners. They can also combine with other C.O.M.B.A.T. weapons to form bigger and badder guns.

Weaponizer Mini-Cons can remotely control the bodies of larger Cybertronians, even while they are unconscious.

Despite being unable to transform, Action Masters are harder, better, faster, stronger and more alive than regular Cybertronians.

Weaknesses
Not all Cybertronians can transform, as those predating the Second Cybertronian Civil War may not have this ability. There is also a limit to what kind of alternate modes a Cybertronian can assume, as they cannot assume a form larger than their robot mode.

Cybertronians are vulnerable to unnatural diseases and "uberpredators" such as Unicron, Primacron, and Cosmic Rust.

Cybertronians from the Malgus Cluster are unable to safely become a triple or six changer because adopting multiple alternate modes would strain their bodies to the point of affecting their mental state, as demonstrated with Blitzwing.

Cybertronians are vulnerable to magic and other exotic forms of power. Similarly, they can be affected by reality manipulations.

Cybertronians are vulnerable to being controlled by parasitic life forms.

Cybertronians are sensitive to electromagnetic projections. They can also be either disabled or restrained by Cybertronian stasis cuffs.

There is a limit to a Cybertronian's durability, as their armor is vulnerable to the most extreme temperatures. As such, this armor can be damaged or breached with either sufficient pressure or special materials and weapons. Similarly, their internal workings and other functions are vulnerable to being hacked, damaged, or overloaded.

Custom-forged and augmented Cybertronians can have trouble fighting against sufficiently powerful opponents and forces, indicating a limit to their physical strength.

Cybertronians can be immobilized or hampered in both vehicle mode and robot mode if they receive severe damage to either of their forms.

Despite being machines, Cybertronians are still susceptible to exhaustion. Similarly, if they either receive enough damage or go too long without refueling, they will shut down and possibly enter stasis lock.

Culture and society
Throughout the multiverse, Cybertronians are divided into multiple factions, the most common being the heroic Autobots led by Optimus Prime and the evil Decepticons led by Megatron.

In many timelines, the Autobots are succeeded by the Maximals, who are led by Optimus Primal and generally transform into mammals, birds, and aquatic life. Likewise, the Decepticons are succeeded by the Predacons, who are led by Galavar (aka "Beast" Megatron) and generally transform into dinosaurs, other reptiles, insects, and amphibians.

Various subgroups of the above factions exist, including:
 * The Dinobots, Autobots who transform into robotic dinosaurs.
 * The Insecticons, Decepticons who transform into giant robotic insects.
 * The Constructicons, Decepticons who transform into construction vehicles.
 * The Aerialbots, Autobots who transform into fighter jets and other aerial vehicles.
 * The Stunticons, Decepticons who transform into sports card and other ground vehicles.
 * The Protectobots, Autobots who transform into emergency, rescue, and law enforcement vehicles.
 * The Combaticons, Decepticons who transform into military vehicles.
 * The Monsterbots, Autobots who transform into monsteous robotic animals.
 * The Horrorcons, Decepticons who transform into monstrous robotic animals.
 * The Technobots, Autobots who transform into future vehicles.
 * The Seacons, Decepticons who transform into robotic sea creatures.
 * The Trainbots, Autobots who transform into trains.

Certain Cybertronians are affiliated with the Quintessons, such as the Terrorcons, who transform into monstrous robotic reptiles; and Predacons, who transform into savage robotic animals.
 * The "Terrorcon" name also refers to mass-produced Decepticons with animalistic alternate modes in the Aurex cluster and undead Cybertronians in the Uniend cluster.
 * In addition to the aforementioned faction, the "Predacon" name has been used to describe ancient animalistic Cybertronians in the Uniend cluster.

Other known Cybertronian factions include the Vehicons, mass-produced drones with connections to the Decepticons and/or Predacons; the Star Seekers, space pirates led by Thundertron; and the Mercenaries, dangerous yet skilled operatives whose only allegiance is to whichever side they find most beneficial at any given time.

Technology
Cybertronian technology has developed to the point where they can convert most forms of energy into Energon.

The Cybertronian Omnifunctional Modular Battlefield Assault Tech System, or C.O.M.B.A.T. System, is a type of modular weapons technology purported to be the most advanced in the universe. Employed by Cybertronians in the final days of their conflict on Cybertron, C.O.M.B.A.T. weapons can convert into alternate forms suited for different types of combat or combine to become bigger and stronger.

The Adaptable Interconnection Retrofitter Lock System, or A.I.R. Lock System, is a type of modular technology in which platforms, ramps, and more can be connected together to form bases and battle scenes. The system has used by Cybertronians during their search for the AllSpark on Earth to create bases for themselves.

The Fossilized Osteo-Skeletal Shield Integration Loadout Technology, or F.O.S.S.I.L. Technology, is an ancient and highly advanced technology that can unleash the primal power of the beasts.

Religion
It is a common belief amongst Maximals that their sparks are either part of or fragments of Primus, the mythical creator of the Cybertronian race.

General
The Cybertronian species is an old race with an odd and murky tale that is their origin. Various accounts claim they created by either the Quintessons or a deity known as Primus, while others claim that they came into existence by a relic known as the AllSpark and some even say they evolved like most organic species.

Primax Cluster
The earliest records we have of Cybertronian history is during a point when they were enslaved by the Quintessons, the future divided factions were originally sold in two product lines, the Autobots were sold as consumer products and the Decepticons were military hardware. After fully achieving sapience, the Cybertronians rose up against their oppressors and became more then just "robots".

Unfortunately, the two sides just didn't see eye to eye, and so began the many Civil Wars of the Cybertronian people. During the second of these civil wars, the Cybertronians had a micro-evolution which gave them their most notable ability, the power of Transforming!

With this new ability at their fingertips, their people began a Golden Age, for themselves, and their planet. However, this age came to a screeching halt when some Decepticons created their new leader, Megatron.

Under this new leadership, the Decepticons rose up, and took most of the planet for themselves. Along the way, Megatron nearly killed a dock worker known as Orion Pax, who later became a prime and led the Autobots off the planet in search of more energy. Little did they know, the Decepticons were in pursuit of their spacecraft. Following the short confrontation, the Autobot ship with the Decepticons still inside crash-landed into a mountain on Earth where they remained in a vegetative state for millions of years before awakening in 1984 and continuing their battles.

Eventually by the year 2005, the Autobots had established a permanent base on Earth and outposts on Cybertron's two moons, whereas the Decepticons had fully conquered Cybertron itself. Unfortunately, before both moons were devoured by Unicron. After the battle with the monster planet, the Autobots had finally reclaimed their home and the surviving Decepticons fled to the planet Charr. After more conflicts with Galvatron's Decepticons, the Quintessons, and the Nebulons, they Autobots finally won the war and all was well.

In certain universe, there were some smaller conflicts in Earth's prehistoric past between Maximals and Predacons, time-travelling descendants of the Autobots and Decepticons.
