Predacons

Originally a splitter grope from the Primals. The Predacons are one of the two factions who control the Maxicon Terriotories.  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 and the Maximals eventually became the main two Cybertronian factions in the Galaxy before the Commandrons came into power

History:

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

Very Early on the Primal faction split into the Maximals and Predacons 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 criminal group. 

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.
