Omega Supreme

"Omega Supreme Functional. Systems: Optimal. Repairs: Unnecessary." —Omega Supreme sums up his status.

Omega Supreme is perhaps the last of the great Guardians who once roamed Cybertron. Omega is considered to be the strongest of any and all Autobots to the point that he strikes fear into the Sparks of almost every single Decepticon he faces in the battlefield. As the last line of defense for Iacon and the guardian for the gateway to Cybertron's Core, Omega Supreme is nearly unstoppable. Once he has a mission set before him, nothing will stop him from seeing it through.

While appearing to be a giant Autobot Weapon, Omega Supreme is actually a very caring Autobot, looking out for the life-forms around him, be they Cybertronian or Human. This great Guardian may have been charged with Iacon's protection, but he eventually found his way to Earth where he now helps the Autobots protect the Humans from the cruelty of the tyrannical Decepticons.

He also apparently batted Skywarp all the way from Cybertron to Earth... Whoa.
