Omega Supreme is one of the largest Autobots, and perhaps the most powerful. He isn't much for words; his mountainous frame and vast firepower tend to do the talking for him. He is the last line of the Autobot defense, and this responsibility gives him a solemn, even grim personality - for he knows that if a battle calls for his involvement, the rest of his team must have already fallen. This titanic last survivor of the Guardian robots instills fear and panic into the sparks of Decepticons foolhardy enough to stand against him in battle.
