Road Caesar is an Autobot combiner from the Victory portion of the Generation 1 continuity family.
Road Caesar is the combined form of the Brainmasters, and a warrior almost without compare. Unlike many of his combiner predessors, who suffered from limited intelligence or other impalements when combined, Road Caesar is a perfect fusion of his components members. He brings together the strength of Braver, the skill of Laster and intelligence of Braver to create a being of truly indomitable fighting spirit. If one were to call Star Saber the "King of the skies," then there's no question that Road Caesar is the king of the land. And when these two kings fight side by side, the Decepticons always know they're in for a royal thrashing.
Road Caesar wields the mighty "Road Blade", a massive sword formed from the combination of Blacker, Braver and Laster's individual blades. But even this weapon pales in comparison to his "Brain Wheel Shocker" technique, which sees Road Caesar launch rings of super-energy from all twelve of his tires. Even his opposite number, the Decepticon Liokaiser, can't stand up to this automotive onslaught.
