Ultra Magnus is the supreme commander of the Autobots and leader of the Autobot Elite Guard in Transformers: Animated. He transforms into a blue and white Heavy Expanded Mobility Tactical Truck, and wields the Magnus Hammer, an enormous hammer passed down to each new Magnus and capable of summoning lightning.
Long ago, Ultra Magnus was trained in learning how to use melee weapons by Yoketron. In the third season, Ultra Magnus is attacked and nearly killed by Shockwave with him ending up in a coma. It is unknown if he ever recovers from it, but details of the planned fourth season would indicate that Ultra Magnus would die.
