Predacons

 Originally a splitter grope from the autobot sub grope the Maximals. The Predacons became a Decepticon sub grope during the war their quite rare. Originating from Eukaris their biology slightly differs from the main species of transformers by able to mimic the outside appearance of Organics better then any normal bot.

After the war they became their own faction and eventually took over along with the Maximals before reuniting at last as the Commandrons.

History:

The predacons were originally from the Maximal project made by Cerebros and Plasma to make a cybertronian which could better disguise themselves on a Organic world without technology.

Some of these Maximals didn't like their fellow Maximals and separated away from their birth faction and became a new grope dubbed the Predacons. One group within the predacons lead by Cryotek and Ghawnsteeth became a notorious terrorist group. 

During sentinel's time Cryotek terrify Predacon grope made an alliance with the Decepticons and became allies. They were aloud to where their own symbols but couldn't get more in their ranks.

During the war Cryotek grope became Nomads living in space within their ship the Predica while the others preds stayed on Eukaris. All ways trying to chase their Maximal foes. Eventually 3 million years ago this led them to earth

Once the war finished their was a growth in predacons and Maximals compared to new generations of Autobots and Decepticons. This started the Maxicon era when Rodimus prime gave way and led the Maxicon government rule.
