Decepticons

The Decepticons are a race of Villainous Robotic race from the Transformers multiverse that broke away from the Autobots, causing a civil war that lasted for thousands of millennia.

Beginnings as a Slave Race & Liberation
The Decepticons like the Autobots were creations of the Quintessons. They were their slaves on Cybertron. While the Autobots were the worker caste, the Decepticons were the warrior caste. They would fight the wars for the Quintessons and even each other in gladiatorial fights simply out of amusement for the Quintessions. After a while, both Autobot and Decepticon Cybertrionians developed emotions. They were becoming self-aware. Neither side wished to be slaves. So they united in one case, to defeat the Quintessions.

The Decepticons with the aid of the Autobots fought in a war to liberate Cybertron against their cruel masters. After a long fought struggle, the Autobots and Decepticons exiled their former masters off Cybertron. And for a time after, both sides lived in harmony. But all things do not last forever, this age of peace was no exception to that rule.

The First Great War
The Decepticons felt they were the more powerful race since they were the warriors and wanted to take power for themselves. But the Autobots did not desire this and a civial war broke out. For millions of years they fought. Both sides had many leaders but two seemed to have stand out. The first of these two leaders was Megatron, the most ruthless, merciless, and deadly Decepticon that has ever been created. He lead the Decepticons to several victories, that is until he deceived and nearly killed Orion Pax. Orion was reformatted into the first battle-ready Autobot, Optimus Prime. The Great War would get even bloodier. It exhausted Cybertron's energy, turning the once golden planet into a near silver dying world. Both sides decided they needed to find a new source of power. Optimus Prime plotted a trip to Earth. On the way, Megatron had the followed the Autonots on his own ship with his best Decepticon warriors. They boarded the Autobot ship and they fought all the way to Earth. Meanwhile back on Cybertron, the war raged on with the defacto Decepticon leader, Shockwave, to take up Megatron's duties until his return.

Millions of years later in the Earth year, 1984, Teletran 1, the computer onboard the Autobot ship awoke and repaired both factions and reformatted their alternate forms to resemble Earth vehicles. The war would be brought to Earth. For the next 21 years, the final battles of The Great War was fought until in 2005 the Decepticons invaded Autobot City. It was a bloody fight in which many Decepticons and Autobots were lost, including Megatron and Optimus Prime. This would also be the time when their greatest enemy would come, Unicron. He reformatted a damaged Megatron and a few of his troops. Megatron was renamed Galvatron. However, shortly after, Unicron destroyed Cybertron's two moon bases. After a few more battles, They would once again reunited in a common goal against Unicron. However, Unicron forced Galvatron to fight the Autobot, Hot Rod. In the fight, Hot Rod opened the Matrix and was reformatted into Rodimus Prime and defeated Galvatron before he destroyed Unicron. The Decepticons were in no condition to fight the Autobots so they retreated from Cybertron in defeat. The First Great War was over.

The Second Great War
The Decepticons were living on a wasteland planet known as Chaar. With very little energy, they were reduced to weakened scavengers. They fought each other for energy and were no condition to wage war against The Autobots. However, an elite team of Decepticons decided that they needed to get back Galvatron to restore them to glory. They went in search of Galvatron and once they found him, he was insane. He would abuse his troops, but despite this, they still needed him. However, the Quintessons returned after they encounted the Autobots shortly after Optimus died, and took the Decepticons from Chaar before Galvatron can return and pit them against the Autobots. The Second Great War begun.

After nearly one Earth year in the war, the Autobots, Decepticons, and even the Quintessons were once again facing a common enemy, but this time it was a disease known as The Hate Plague. It would infect anyone, human, Cybertronian, animal...anything. It was originally a plot that was devised by a human who wanted to get his revenge on the Cybertronians for destroying his lab and the injuries to his daughter. During these events, Optimus was resurrected and he got rid of the plague and resumed his duties of being Autobot leader. Galvatron called for a temporary cease-fire.

However, the war would resume when The Decepticons stole the Key to a Plasma Chamber from The Autobots. This would drag the planet of Nebulous into the war. The Nebulans evil race, The Hive joined forces with The Decepticons. When they discovered that the Autobots are headmasters, the Hive and a few Decepticons became Headmasters, some others became target masters. They fought The Autobots and The Nebulian resistance who themselves were head and target masters. meanwhile Galvatron brought Cybertron to Earth. When the Autobots and Decepticons returned to Earrth, Galvatron out of pure madness opened the plasma energy chamber. Though little did he know, he was forfilling a prophecy that the Matrix revealed to Optimus Prime that this would start Cybertron's second golden age.

The Decepticons lost, but Galvatron vowed he would rule the Galaxy. The Second Great War might have come to an end, but the battle to take control of Cybertron would rage on.
