Decepticons

The Decepticons are a group of Cybertronians and are major supporting characters in Super Smash Bros. Brawl. They are arch enemies of the Autobots and are led by Megatron. For many centuries The Decepticons have battled against the Autobots across many planets such as Cybertron and Earth and later many other planets. They have received the name "Decepticon" where it comes from deceive they were once Autobots in the 16th century where Megatronus(aka The Fallen) had led a gang of Cybertronians into stealing goods on Earth and later rebelled against his Prime Brotherhood and changed their symbol. Centuries later after The Great Destruction, the Decepticons receive reports of having sightings of shape shifting creatures composed of metal infecting other Cybertronians, they check the investigation only to challenge an outbreak by them now known as Metalers forcing them to flee on many planets. Over time in the year 2015, the frequency of the Metalers appearing emerged rapidly and began plaguing various bases around the world. In response to the massive plague, the Decepticons have launched their ships into their hostile remote planet Metally and have begun colonizing and researching the planet.
