High Quality Content by WIKIPEDIA articles! Rad is the name of two fictional characters in the Transformers universes. Rad is an Autobot Action Master. He has a Targetmaster partner named Lionizer. With more moves than an all-pro halfback, this clever, cool-headed daredevil is equally adept at combating Decepticons or calculating the coefficient of friction for a rocket booster. Paired with Lionizer, a roaring raging bundle of overheated circuits who can change into an atom-smashing blaster at the drop of a microchip... unless Rad can cool his engines first.
